-Efficient VM backup for qemu
-
-=Requirements=
-
-* Backup to a single archive file
-* Backup needs to contain all data to restore VM (full backup)
-* Do not depend on storage type or image format
-* Avoid use of temporary storage
-* store sparse images efficiently
-
-=Introduction=
-
-Most VM backup solutions use some kind of snapshot to get a consistent
-VM view at a specific point in time. For example, we previously used
-LVM to create a snapshot of all used VM images, which are then copied
-into a tar file.
-
-That basically means that any data written during backup involve
-considerable overhead. For LVM we get the following steps:
-
-1.) read original data (VM write)
-2.) write original data into snapshot (VM write)
-3.) write new data (VM write)
-4.) read data from snapshot (backup)
-5.) write data from snapshot into tar file (backup)
-
-Another approach to backup VM images is to create a new qcow2 image
-which use the old image as base. During backup, writes are redirected
-to the new image, so the old image represents a 'snapshot'. After
-backup, data need to be copied back from new image into the old
-one (commit). So a simple write during backup triggers the following
-steps:
-
-1.) write new data to new image (VM write)
-2.) read data from old image (backup)
-3.) write data from old image into tar file (backup)
-
-4.) read data from new image (commit)
-5.) write data to old image (commit)
-
-This is in fact the same overhead as before. Other tools like qemu
-livebackup produces similar overhead (2 reads, 3 writes).
-
-Some storage types/formats supports internal snapshots using some kind
-of reference counting (rados, sheepdog, dm-thin, qcow2). It would be possible
-to use that for backups, but for now we want to be storage-independent.
-
-=Make it more efficient=
-
-The be more efficient, we simply need to avoid unnecessary steps. The
-following steps are always required:
-
-1.) read old data before it gets overwritten
-2.) write that data into the backup archive
-3.) write new data (VM write)
-
-As you can see, this involves only one read, and two writes.
-
-To make that work, our backup archive need to be able to store image
-data 'out of order'. It is important to notice that this will not work
-with traditional archive formats like tar.
-
-During backup we simply intercept writes, then read existing data and
-store that directly into the archive. After that we can continue the
-write.
-
-==Advantages==
-
-* very good performance (1 read, 2 writes)
-* works on any storage type and image format.
-* avoid usage of temporary storage
-* we can define a new and simple archive format, which is able to
- store sparse files efficiently.
-
-Note: Storing sparse files is a mess with existing archive
-formats. For example, tar requires information about holes at the
-beginning of the archive.
-
-==Disadvantages==
-
-* we need to define a new archive format
-
-Note: Most existing archive formats are optimized to store small files
-including file attributes. We simply do not need that for VM archives.
-
-* archive contains data 'out of order'
-
-If you want to access image data in sequential order, you need to
-re-order archive data. It would be possible to to that on the fly,
-using temporary files.
-
-Fortunately, a normal restore/extract works perfectly with 'out of
-order' data, because the target files are seekable.
-
-* slow backup storage can slow down VM during backup
-
-It is important to note that we only do sequential writes to the
-backup storage. Furthermore one can compress the backup stream. IMHO,
-it is better to slow down the VM a bit. All other solutions creates
-large amounts of temporary data during backup.
-
-=Archive format requirements=
-
-The basic requirement for such new format is that we can store image
-date 'out of order'. It is also very likely that we have less than 256
-drives/images per VM, and we want to be able to store VM configuration
-files.
-
-We have defined a very simply format with those properties, see:
-
-https://git.proxmox.com/?p=pve-qemu-kvm.git;a=blob;f=vma_spec.txt;
-
-Please let us know if you know an existing format which provides the
-same functionality.

-Subject: [PATCH v5 0/6] Efficient VM backup for qemu
-
-This series provides a way to efficiently backup VMs.
-
-* Backup to a single archive file
-* Backup contain all data to restore VM (full backup)
-* Do not depend on storage type or image format
-* Avoid use of temporary storage
-* store sparse images efficiently
-
-The file docs/backup.txt contains more details.
-
-Changes since v1:
-
-* fix spelling errors
-* move BackupInfo from BDS to BackupBlockJob
-* introduce BackupDriver to allow more than one backup format
-* vma: add suport to store vmstate (size is not known in advance)
-* add ability to store VM state
-
-Changes since v2:
-
-* BackupDriver: remove cancel_cb
-* use enum for BackupFormat
-* vma: use bdrv_open instead of bdrv_file_open
-* vma: fix aio, use O_DIRECT
-* backup one drive after another (try to avoid high load)
-
-Changes since v3:
-
-* move reviewer info from commit messages to cover-letter
-* remove 'RFC' from log headers and file names
-* removed comment about slow qcow2 snapshot bug
-* fix spelling errors
-* fixed copyright
-* change 'backupfile' parameter name to 'backup-file'
-* change 'config-filename' parameter name to 'config-file'
-* add documentation for 'devlist' parameter.
-* rename backup_cancel to backup-cancel
-
-Changes since v4:
-
-* vma create: write verbose output to stderr (not stdout)
-* backup.c: use rwlock instead of sleep, remove backup_in_progress_count
-* BackupDriver: remove '_cb' suffix
-* include cleanups suggested by Stefan
-* use CHAR_BIT instead of magic number '8'
-* implemented bdrv_co_is_allocated_above() - disabled for now because
- it actually slows down backup speed by 15%
-* extend regression tests to test unallocated regions
-
-Dietmar Maurer (6):
- add documenation for new backup framework
- add basic backup support to block driver
- add backup related monitor commands
- introduce new vma archive format
- add regression tests for backup
- add vm state to backups

-+Efficient VM backup for qemu
-+
-+=Requirements=
-+
-+* Backup to a single archive file
-+* Backup needs to contain all data to restore VM (full backup)
-+* Do not depend on storage type or image format
-+* Avoid use of temporary storage
-+* store sparse images efficiently
-+
-+=Introduction=
-+
-+Most VM backup solutions use some kind of snapshot to get a consistent
-+VM view at a specific point in time. For example, we previously used
-+LVM to create a snapshot of all used VM images, which are then copied
-+into a tar file.
-+
-+That basically means that any data written during backup involve
-+considerable overhead. For LVM we get the following steps:
-+
-+1.) read original data (VM write)
-+2.) write original data into snapshot (VM write)
-+3.) write new data (VM write)
-+4.) read data from snapshot (backup)
-+5.) write data from snapshot into tar file (backup)
-+
-+Another approach to backup VM images is to create a new qcow2 image
-+which use the old image as base. During backup, writes are redirected
-+to the new image, so the old image represents a 'snapshot'. After
-+backup, data need to be copied back from new image into the old
-+one (commit). So a simple write during backup triggers the following
-+steps:
-+
-+1.) write new data to new image (VM write)
-+2.) read data from old image (backup)
-+3.) write data from old image into tar file (backup)
-+
-+4.) read data from new image (commit)
-+5.) write data to old image (commit)
-+
-+This is in fact the same overhead as before. Other tools like qemu
-+livebackup produces similar overhead (2 reads, 3 writes).
-+
-+Some storage types/formats supports internal snapshots using some kind
-+of reference counting (rados, sheepdog, dm-thin, qcow2). It would be possible
-+to use that for backups, but for now we want to be storage-independent.
-+
-+=Make it more efficient=
-+
-+The be more efficient, we simply need to avoid unnecessary steps. The
-+following steps are always required:
-+
-+1.) read old data before it gets overwritten
-+2.) write that data into the backup archive
-+3.) write new data (VM write)
-+
-+As you can see, this involves only one read, and two writes.
-+
-+To make that work, our backup archive need to be able to store image
-+data 'out of order'. It is important to notice that this will not work
-+with traditional archive formats like tar.
-+
-+During backup we simply intercept writes, then read existing data and
-+store that directly into the archive. After that we can continue the
-+write.
-+
-+==Advantages==
-+
-+* very good performance (1 read, 2 writes)
-+* works on any storage type and image format.
-+* avoid usage of temporary storage
-+* we can define a new and simple archive format, which is able to
-+ store sparse files efficiently.
-+
-+Note: Storing sparse files is a mess with existing archive
-+formats. For example, tar requires information about holes at the
-+beginning of the archive.
-+
-+==Disadvantages==
-+
-+* we need to define a new archive format
-+
-+Note: Most existing archive formats are optimized to store small files
-+including file attributes. We simply do not need that for VM archives.
-+
-+* archive contains data 'out of order'
-+
-+If you want to access image data in sequential order, you need to
-+re-order archive data. It would be possible to to that on the fly,
-+using temporary files.
-+
-+Fortunately, a normal restore/extract works perfectly with 'out of
-+order' data, because the target files are seekable.
-+
-+* slow backup storage can slow down VM during backup
-+
-+It is important to note that we only do sequential writes to the
-+backup storage. Furthermore one can compress the backup stream. IMHO,
-+it is better to slow down the VM a bit. All other solutions creates
-+large amounts of temporary data during backup.
-+
-+=Archive format requirements=
-+
-+The basic requirement for such new format is that we can store image
-+date 'out of order'. It is also very likely that we have less than 256
-+drives/images per VM, and we want to be able to store VM configuration
-+files.
-+
-+We have defined a very simply format with those properties, see:
-+
-+docs/specs/vma_spec.txt
-+
-+Please let us know if you know an existing format which provides the
-+same functionality.

-Subject: [PATCH] aio: Fix use-after-free in cancellation path
-
-The current flow of canceling a thread from THREAD_ACTIVE state is:
-
- 1) Caller wants to cancel a request, so it calls thread_pool_cancel.
-
- 2) thread_pool_cancel waits on the conditional variable
- elem->check_cancel.
-
- 3) The worker thread changes state to THREAD_DONE once the task is
- done, and notifies elem->check_cancel to allow thread_pool_cancel
- to continue execution, and signals the notifier (pool->notifier) to
- allow callback function to be called later. But because of the
- global mutex, the notifier won't get processed until step 4) and 5)
- are done.
-
- 4) thread_pool_cancel continues, leaving the notifier signaled, it
- just returns to caller.
-
- 5) Caller thinks the request is already canceled successfully, so it
- releases any related data, such as freeing elem->common.opaque.
-
- 6) In the next main loop iteration, the notifier handler,
- event_notifier_ready, is called. It finds the canceled thread in
- THREAD_DONE state, so calls elem->common.cb, with an (likely)
- dangling opaque pointer. This is a use-after-free.
-
-Fix it by calling event_notifier_ready before leaving
-thread_pool_cancel.
-
-Test case update: This change will let cancel complete earlier than
-test-thread-pool.c expects, so update the code to check this case: if
-it's already done, done_cb sets .aiocb to NULL, skip calling
-bdrv_aio_cancel on them.

-
-qemu_bh_schedule() is supposed to be thread-safe at least the first time
-it is called. Unfortunately this is not quite true:
-
- bh->scheduled = 1;
- aio_notify(bh->ctx);
-
-Since another thread may run the BH callback once it has been scheduled,
-there is a race condition if the callback frees the BH before
-aio_notify(bh->ctx) has a chance to run.

-Subject: [PATCH v5 3/6] add backup related monitor commands
-
-We use a generic BackupDriver struct to encapsulate all archive format
-related function.
-
-Another option would be to simply dump <devid,cluster_num,cluster_data> to
-the output fh (pipe), and an external binary saves the data. That way we
-could move the whole archive format related code out of qemu.

-+=Virtual Machine Archive format (VMA)=
-+
-+This format contains a header which includes the VM configuration as
-+binary blobs, and a list of devices (dev_id, name).
-+
-+The actual VM image data is stored inside extents. An extent contains
-+up to 64 clusters, and start with a 512 byte header containing
-+additional information for those clusters.
-+
-+We use a cluster size of 65536, and use 8 bytes for each
-+cluster in the header to store the following information:
-+
-+* 1 byte dev_id (to identity the drive)
-+* 1 byte not used (reserved)
-+* 2 bytes zero indicator (mark zero regions (16x4096))
-+* 4 bytes cluster number
-+
-+We only store non-zero blocks (such block is 4096 bytes).
-+
-+Each archive is marked with a uuid. The archive header and all
-+extent headers includes that uuid and a MD5 checksum (over header
-+data).

-Subject: [PATCH v3 7/7] use extra thread for vma writer
-
-The previous AIO approach has problem with bdrv_drain_all(), because writer
-coroutines are not considered there. Those coroutines are not restarted, so
-bdrv_drain_all() can fail (tracked_requests list not empty).
-
-We now use a thread, so we could also add compression here.

-Subject: [PATCH] net/vmxnet3: Refine l2 header validation
-
-Validation of l2 header length assumed minimal packet size as
-eth_header + 2 * vlan_header regardless of the actual protocol.
-
-This caused crash for valid non-IP packets shorter than 22 bytes, as
-'tx_pkt->packet_type' hasn't been assigned for such packets, and
-'vmxnet3_on_tx_done_update_stats()' expects it to be properly set.
-
-Refine header length validation in 'vmxnet_tx_pkt_parse_headers'.
-Check its return value during packet processing flow.
-
-As a side effect, in case IPv4 and IPv6 header validation failure,
-corrupt packets will be dropped.

-Subject: [PATCH] ide: ahci: reset ncq object to unused on error
-
-When processing NCQ commands, ACHI device emulation prepares a
-NCQ transfer object; To which an aio control block(aiocb) object
-is assigned in 'execute_ncq_command'. In case, when the NCQ
-command is invalid, the 'aiocb' object is not assigned, and NCQ
-transfer object is left as 'used'. This leads to a use after
-free kind of error in 'bdrv_aio_cancel_async' via 'ahci_reset_port'.
-Reset NCQ transfer object to 'unused' to avoid it.

-Subject: [Qemu-devel] [PATCH] ahci: add migration support
-Date: Thu, 30 Aug 2012 14:00:04 -0400
-
-Add support for ahci migration. This patch builds upon the patches posted
-previously by Andreas Faerber:
-
-http://lists.gnu.org/archive/html/qemu-devel/2012-08/msg01538.html
-
-(I hope I am giving Andreas proper credit for his work.)
-
-I've tested these patches by migrating Windows 7 and Fedora 16 guests on
-both piix with ahci attached and on q35 (which has a built-in ahci controller).

-run vma_writer_close_stream inside coroutine

-Newer qemu (> 2.2.0-rc2) runs pvebackup_complete_cb from main loop,
-
-But vma_writer_close_stream triggers an async write (flush), which uses qemu_coroutine_yield(). This only works if called from a coroutine.

-Subject: configure: Add support for jemalloc
-From: Alexandre DERUMIER <aderumier@odiso.com>

-Message-Id: <1434711418-20429-1-git-send-email-aderumier@odiso.com>

-
-This adds "--enable-jemalloc" and "--disable-jemalloc" to allow linking
-to jemalloc memory allocator.
-
-We have already tcmalloc support,
-but it seem to not working well with a lot of iothreads/disks.
-
-The main problem is that tcmalloc use a shared thread cache of 16MB
-by default.
-With more threads, this cache is shared, and some bad garbage collections
-can occur if the cache is too low.
-
-It's possible to tcmalloc cache increase it with a env var:
-TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=256MB
-
-With default 16MB, performances are really bad with more than 2 disks.
-Increasing to 256MB, it's helping but still have problem with 16 disks/iothreads.
-
-Jemalloc don't have performance problem with default configuration.
-
-Here the benchmark results in iops of 1 qemu vm randread 4K iodepth=32,
-with rbd block backend (librbd is doing a lot of memory allocation),
-1 iothread by disk

- 1/1] block: mirror - fix full sync mode when target does not support
- zero init
-From: Jeff Cody <jcody@redhat.com>
-X-Patchwork-Id: 525278
-Message-Id: <1443726328-29484-2-git-send-email-jcody@redhat.com>
-To: qemu-block@nongnu.org

-
-During mirror, if the target device does not support zero init, a
-mirror may result in a corrupted image for sync="full" mode.
-
-This is due to how the initial dirty bitmap is set up prior to copying
-data - we did not mark sectors as dirty that are unallocated. This
-means those unallocated sectors are skipped over on the target, and for
-a device without zero init, invalid data may reside in those holes.
-
-If both of the following conditions are true, then we will explicitly
-mark all sectors as dirty:
-
- 1.) sync = "full"
- 2.) bdrv_has_zero_init(target) == false
-
-If the target does support zero init, but a target image is passed in
-with data already present (i.e. an "existing" image), it is assumed the
-data present in the existing image is valid data for those sectors.

-+virtio balloon memory statistics
-+================================
-+
-+The virtio balloon driver supports guest memory statistics reporting. These
-+statistics are available to QEMU users as QOM (QEMU Object Model) device
-+properties via a polling mechanism.
-+
-+Basically, clients first have to enable polling, then they can query the
-+available statistics.
-+
-+There are two control properties and six memory statistics properties.
-+
-+The control properties are:
-+
-+ o stats-polling-interval: polling time interval in seconds, it can be:
-+
-+ > 0 enables polling in the specified interval. If polling is already
-+ enabled, the polling time interval will be changed to the new value
-+
-+ 0 disables polling. Previous polled statistics are still valid and
-+ can be queried.
-+
-+ o stats-last-update: last stats update timestamp, in seconds
-+
-+The following statistics are available, all values are in bytes:
-+
-+ o stat-swap-in
-+ o stat-swap-out
-+ o stat-major-faults
-+ o stat-minor-faults
-+ o stat-free-memory
-+ o stat-total-memory
-+
-+Also, please note the following:
-+
-+ - If a statistic is queried before the timer is enabled or if the guest
-+ doesn't support a particular statistic, an error will be returned
-+
-+ - Previously polled statistics remain available even if the timer is
-+ later disabled
-+
-+ - Polling can be enabled even if the guest doesn't support memory
-+ statistics or its balloon driver hasn't been loaded. Applications
-+ can check this condition by checking that stats-last-update doesn't
-+ change
-+
-+ - The polling timer is only re-armed when the guest responds to the
-+ statistics request. This means that if a (buggy) guest doesn't
-+ ever respond to the request the timer will never be re-armed,
-+ which has the same effect as disabling polling
-+
-+Here are a few examples. The virtio-balloon device is assumed to be in the
-+'/machine/peripheral-anon/device[1]' QOM path.
-+
-+Enable polling with 2 seconds interval:
-+
-+{ "execute": "qom-set",
-+ "arguments": { "path": "/machine/peripheral-anon/device[1]",
-+ "property": "stats-polling-interval", "value": 2 } }
-+
-+{ "return": {} }
-+
-+Change polling to 10 seconds:
-+
-+{ "execute": "qom-set",
-+ "arguments": { "path": "/machine/peripheral-anon/device[1]",
-+ "property": "stats-polling-interval", "value": 10 } }
-+
-+{ "return": {} }
-+
-+Get last update timestamp and free memory stat:
-+
-+{ "execute": "qom-get",
-+ "arguments": { "path": "/machine/peripheral-anon/device[1]",
-+ "property": "stats-last-update" } }
-+
-+{ "return": 1354629634 }
-+
-+{ "execute": "qom-get",
-+ "arguments": { "path": "/machine/peripheral-anon/device[1]",
-+ "property": "stat-free-memory" } }
-+
-+{ "return": 845115392 }
-+
-+Disable polling:
-+
-+{ "execute": "qom-set",
-+ "arguments": { "path": "/machine/peripheral-anon/device[1]",
-+ "property": "stats-polling-interval", "value": 0 } }
-+
-+{ "return": {} }

-The statistics are now available through device properties via a
-polling mechanism. First a client has to enable polling, then it
-can query each stat individually.
-
-The following control properties are introduced:
-
- o stats-polling-interval: a value greater than zero enables polling
- in the specified interval (in seconds). When value equals zero,
- polling is disabled. If polling is already enabled and a value
- greater than zero is written, the polling interval time is changed
-
- o stats-last-update: last stats update timestamp, in seconds.
-
-The following stats properties are introduced, all values are in bytes:
-
- o stat-swap-in
- o stat-swap-out
- o stat-major-faults
- o stat-minor-faults
- o stat-free-memory
- o stat-total-memory
-
-Please, refer to the documentation introduced by the next commit for
-more information and examples.

-Subject: [PATCH] net: vmxnet3: avoid memory leakage in activate_device
-
-Vmxnet3 device emulator does not check if the device is active
-before activating it, also it did not free the transmit & receive
-buffers while deactivating the device, thus resulting in memory
-leakage on the host. This patch fixes both these issues to avoid
-host memory leakage.

-Introduces a BackupDump function callback and a pause_count
-for backup_start. For a dump-backup the target parameter
-can now be NULL so access to target needs to be guarded now.

-Subject: [PATCH 34/48] vma: add format option to device mapping
-
-The BDRV_O_PROTOCOL option breaks non-raw protocol devices,
-so we instead now allow the format to be explicitly
-specified from the outside.
-
-In other words we now too deprecate the automatic guessing
-of raw formats, just like qemu already does, and have to
-silence the warnings by passing the drive mapping.

-
-As we else rely on bdrv_close_all() do clean up, which was rewritten
-in ca9bd24cf1d53775169ba9adc17e265554d1afed and fails on "dangling"
-BDS pointers, such a pointer exists with *bs.
-Use the BlockBackend to get our BDS and just unref the BlockBackend
-when done, it handles the rest for us.
-
-The other two calls to bdrv_close_all() happen in verify_content()
-and dump_config(), both do not have a BDS so no need to change here.

-Subject: [PATCH 47/48] glusterfs: allow partial reads
-
-This should deal with qemu bug #1644754 until upstream
-decides which way to go. The general direction seems to be
-away from sector based block APIs and with that in mind, and
-when comparing to other network block backends (eg. nfs)
-treating partial reads as errors doesn't seem to make much
-sense.

-= Virtual Machine Archive format (VMA) =
-
-This format contains a header which includes the VM configuration as
-binary blobs, and a list of devices (dev_id, name).
-
-The actual VM image data is stored inside extents. An extent contains
-up to 64 clusters, and start with a 512 byte header containing
-additional information for those clusters.
-
-We use a cluster size of 65536, and use 8 bytes for each
-cluster in the header to store the following information:
-
-* 1 byte dev_id (to identity the drive)
-* 1 byte not used (reserved)
-* 2 bytes zero indicator (mark zero regions (16x4096))
-* 4 bytes cluster number
-
-We only store non-zero blocks (such block is 4096 bytes).
-
-Each archive is marked with a uuid. The archive header and all
-extent headers includes that uuid and a MD5 checksum (over header
-data).
-
-All numbers in VMA archive are stored in Big Endian byte order.
-
-== VMA Header ==
-
- Byte 0 - 3: magic
- VMA magic string ("VMA\x00")
-
- 4 - 7: version
- Version number (valid value is 1)
-
- 8 - 23: uuid
- Unique ID, Same uuid is used to mark extents.
-
- 24 - 31: ctime
- Backup time stamp (seconds since epoch)
-
- 32 - 47: md5sum
- Header checksum (from byte 0 to header_size). This field
- is filled with zero to generate the checksum.
-
- 48 - 51: blob_buffer_offset
- Start of blob buffer (multiple of 512)
-
- 52 - 55: blob_buffer_size
- Size of blob buffer (multiple of 512)
-
- 56 - 59: header_size
- Overall size of this header (multiple of 512)
-
- 60 - 2043: reserved
-
- 2044 - 3067: uint32_t config_names[256]
- Offsets into blob_buffer table
-
- 3068 - 4091: uint32_t config_data[256]
- Offsets into blob_buffer table
-
- 4092 - 4095: reserved
-
- 4096 - 12287: VmaDeviceInfoHeader dev_info[256]
- The offset in this table is used as 'dev_id' inside
- the data streams.
-
- 12288 - header_size: Blob buffer
-
-
-=== Devive Info Header (VmaDeviceInfoHeader) ===
-
-This is use to store details about the contained disk images.
-
- Byte 0 - 3: devive name (offsets into blob_buffer table)
-
- 4 - 7: reserved
-
- 8 - 15: device size in bytes
-
- 16 - 31: reserved
-
-Note: Devive name 'vmstate' is reserved to store VM RAM state.
-
-=== Blob buffer ===
-
-The blob buffer is used to store both configuration file names and
-configuration data.
-
-This region contain a list of binary data blobs. Each blob starts with
-a 2 byte size field, followed by the actual data.
-
-== Image Data Streams ==
-
-The VMA header is followed by the image data stream. Image data is grouped
-with extents, which contains up to 59 clusters from different images.
-
-=== VMA Extent Header ===
-
- Byte 0 - 3: magic
- VMA extent magic string ("VMAE")
-
- 4 - 5: reserved
-
- 6 - 7: block_count
- Overall number of contained 4K block
-
- 8 - 23: uuid
- Unique ID, Same uuid as used in the VMA header.
-
- 24 - 39: md5sum
- Header checksum (from byte 0 to header_size). This field
- is filled with zero to generate the checksum.
-
- 40 - 511: blockinfo[59]
-
-
-Each 'blockinfo' (8 bytes) give further details about contained clusters:
-
- Byte 0 - 1: mask
- Bitmap used to indicate non-zero 4K blocks inside the
- cluster.
-
- 2: reserved
-
- 3: dev_id
- Device ID (offset into dev_info table)
-
- 4 - 7: cluster_num
-
-The extend header if followed by the actual cluster data, where we only
-store non-zero 4K blocks.
