2 | Dumpling | |
3 | ======== | |
4 | ||
5 | Dumpling is the 4th stable release of Ceph. It is named after the | |
6 | dumpling squid (Euprymna tasmanica). | |

8 | v0.67.12 "Dumpling" (draft) |
9 | =========================== | |
10 | ||
11 | This stable update for Dumpling fixes a few longstanding issues with | |
12 | backfill in the OSD that can lead to stalled IOs. There is also a fix | |
13 | for memory utilization for reads in librbd when caching is enabled, | |
14 | and then several other small fixes across the rest of the system. | |
15 | ||
16 | Dumpling users who have encountered IO stalls during backfill and who | |
17 | do not expect to upgrade to Firefly soon should upgrade. Everyone | |
18 | else should upgrade to Firefly already. This is likely to be the last stable | |
19 | release for the 0.67.x Dumpling series. | |

153 | v0.67.8 "Dumpling" | |
154 | ================== | |
155 | ||
156 | This Dumpling point release fixes several non-critical issues since | |
157 | v0.67.7. The most notable bug fixes are an auth fix in librbd | |
158 | (observed as an occasional crash from KVM), an improvement in the | |
159 | network failure detection with the monitor, and several hard to hit | |
160 | OSD crashes or hangs. | |
161 | ||
162 | We recommend that all users upgrade at their convenience. | |
163 | ||
164 | Upgrading | |
165 | --------- | |
166 | ||
167 | * The 'rbd ls' function now returns success and returns an empty when a pool | |
168 | does not store any rbd images. Previously it would return an ENOENT error. | |
169 | ||
170 | * Ceph will now issue a health warning if the 'mon osd down out | |
171 | interval' config option is set to zero. This warning can be | |
172 | disabled by adding 'mon warn on osd down out interval zero = false' | |
173 | to ceph.conf. | |
174 | ||

212 | v0.67.7 "Dumpling" | |
213 | ================== | |
214 | ||
215 | This Dumpling point release fixes a few critical issues in v0.67.6. | |
216 | ||
217 | All v0.67.6 users are urgently encouraged to upgrade. We also | |
218 | recommend that all v0.67.5 (or older) users upgrade. | |
219 | ||
220 | Upgrading | |
221 | --------- | |
222 | ||
223 | * Once you have upgraded a radosgw instance or OSD to v0.67.7, you should not | |
224 | downgrade to a previous version. | |
225 | ||
226 | Notable Changes | |
227 | --------------- | |
228 | ||
229 | * ceph-disk: additional unit tests | |
230 | * librbd: revert caching behavior change in v0.67.6 | |
231 | * osd: fix problem reading xattrs due to incomplete backport in v0.67.6 | |
232 | * radosgw-admin: fix reading object policy | |
233 | ||
234 | For more detailed information, see :download:`the complete changelog <../changelog/v0.67.7.txt>`. | |
235 | ||
236 | ||
237 | v0.67.6 "Dumpling" | |
238 | ================== | |
239 | ||
240 | .. note: This release contains a librbd bug that is fixed in v0.67.7. Please upgrade to v0.67.7 and do not use v0.67.6. | |
241 | ||
242 | This Dumpling point release contains a number of important fixed for | |
243 | the OSD, monitor, and radosgw. Most significantly, a change that | |
244 | forces large object attributes to spill over into leveldb has been | |
245 | backported that can prevent objects and the cluster from being damaged | |
246 | by large attributes (which can be induced via the radosgw). There is | |
247 | also a set of fixes that improves data safety and RADOS semantics when | |
248 | the cluster becomes full and then non-full. | |
249 | ||
250 | We recommend that all 0.67.x Dumpling users skip this release and upgrade to v0.67.7. | |
251 | ||
252 | Upgrading | |
253 | --------- | |
254 | ||
255 | * The OSD has long contained a feature that allows large xattrs to | |
256 | spill over into the leveldb backing store in situations where not | |
257 | all local file systems are able to store them reliably. This option | |
258 | is now enabled unconditionally in order to avoid rare cases where | |
259 | storing large xattrs renders the object unreadable. This is known to | |
260 | be triggered by very large multipart objects, but could be caused by | |
261 | other workloads as well. Although there is some small risk that | |
262 | performance for certain workloads will degrade, it is more important | |
263 | that data be retrievable. Note that newer versions of Ceph (e.g., | |
264 | firefly) do some additional work to avoid the potential performance | |
265 | regression in this case, but that is current considered too complex | |
266 | for backport to the Dumpling stable series. | |
267 | ||
268 | * It is very dangerous to downgrade from v0.67.6 to a prior version of | |
269 | Dumpling. If the old version does not have 'filestore xattr use | |
270 | omap = true' it may not be able to read all xattrs for an object and | |
271 | can cause undefined behavior. | |
272 | ||
273 | Notable changes | |
274 | --------------- | |
275 | ||
276 | * ceph-disk: misc bug fixes, particularly on RHEL (Loic Dachary, Alfredo Deza, various) | |
277 | * ceph-fuse, libcephfs: fix crash from read over certain sparseness patterns (Sage Weil) | |
278 | * ceph-fuse, libcephfs: fix integer overflow for sync reads racing with appends (Sage Weil) | |

313 | backported features. Also, notably, the 'osd perf' command (which dumps | |

411 | v0.67.2 "Dumpling" | |
412 | ================== | |
413 | ||
414 | This is an important point release for Dumpling. Most notably, it | |
415 | fixes a problem when upgrading directly from v0.56.x Bobtail to | |
416 | v0.67.x Dumpling (without stopping at v0.61.x Cuttlefish along the | |
417 | way). It also fixes a problem with the CLI parsing of the CEPH_ARGS | |
418 | environment variable, high CPU utilization by the ceph-osd daemons, | |
419 | and cleans up the radosgw shutdown sequence. | |
420 | ||
421 | Notable Changes | |
422 | --------------- | |
423 | ||
424 | * objecter: resend linger requests when cluster goes from full to non-full | |
425 | * ceph: parse CEPH_ARGS environment variable | |
426 | * librados: fix small memory leak | |
427 | * osd: remove old log objects on upgrade (fixes bobtail -> dumpling jump) | |
428 | * osd: disable PGLog::check() via config option (fixes CPU burn) | |
429 | * rgw: drain requests on shutdown | |
430 | * rgw: misc memory leaks on shutdown | |

434 | ||
435 | v0.67.1 "Dumpling" | |
436 | ================== | |
437 | ||
438 | This is a minor point release for Dumpling that fixes problems with | |
439 | OpenStack and librbd hangs when caching is disabled. | |
440 | ||
441 | Notable changes | |
442 | --------------- | |
443 | ||
444 | * librados, librbd: fix constructor for python bindings with certain | |
445 | usages (in particular, that used by OpenStack) | |
446 | * librados, librbd: fix aio_flush wakeup when cache is disabled | |
447 | * librados: fix locking for aio completion refcounting | |
448 | * fixes 'ceph --admin-daemon ...' command error code on error | |
449 | * fixes 'ceph daemon ... config set ...' command for boolean config | |
450 | options. | |
451 | ||
452 | For more detailed information, see :download:`the complete changelog <../changelog/v0.67.1.txt>`. | |
453 | ||
454 | v0.67 "Dumpling" | |
455 | ================ | |
456 | ||
457 | This is the fourth major release of Ceph, code-named "Dumpling." The | |
458 | headline features for this release include: | |
459 | ||
460 | * Multi-site support for radosgw. This includes the ability to set up | |
461 | separate "regions" in the same or different Ceph clusters that share | |
462 | a single S3/Swift bucket/container namespace. | |
463 | ||
464 | * RESTful API endpoint for Ceph cluster administration. | |
465 | ceph-rest-api, a wrapper around ceph_rest_api.py, can be used to | |
466 | start up a test single-threaded HTTP server that provides access to | |
467 | cluster information and administration in very similar ways to the | |
468 | ceph commandline tool. ceph_rest_api.py can be used as a WSGI | |
469 | application for deployment in a more-capable web server. See | |
470 | ceph-rest-api.8 for more. | |
471 | ||
472 | * Object namespaces in librados. | |
473 | ||
474 | ||
475 | .. _dumpling-upgrade: | |
476 | ||
477 | Upgrade Sequencing | |
478 | ------------------ | |
479 | ||
480 | It is possible to do a rolling upgrade from Cuttlefish to Dumpling. | |
481 | ||
482 | #. Upgrade ceph-common on all nodes that will use the command line | |
483 | 'ceph' utility. | |
484 | #. Upgrade all monitors (upgrade ceph package, restart ceph-mon | |
485 | daemons). This can happen one daemon or host at a time. Note that | |
486 | because cuttlefish and dumpling monitors can't talk to each other, | |
487 | all monitors should be upgraded in relatively short succession to | |
488 | minimize the risk that an a untimely failure will reduce | |
489 | availability. | |
490 | #. Upgrade all osds (upgrade ceph package, restart ceph-osd daemons). | |
491 | This can happen one daemon or host at a time. | |
492 | #. Upgrade radosgw (upgrade radosgw package, restart radosgw daemons). | |
493 | ||
494 | ||
495 | Upgrading from v0.66 | |
496 | -------------------- | |
497 | ||
498 | * There is monitor internal protocol change, which means that v0.67 | |
499 | ceph-mon daemons cannot talk to v0.66 or older daemons. We | |
500 | recommend upgrading all monitors at once (or in relatively quick | |
501 | succession) to minimize the possibility of downtime. | |
502 | ||
503 | * The output of 'ceph status --format=json' or 'ceph -s --format=json' | |
504 | has changed to return status information in a more structured and | |
505 | usable format. | |
506 | ||
507 | * The 'ceph pg dump_stuck [threshold]' command used to require a | |
508 | --threshold or -t prefix to the threshold argument, but now does | |
509 | not. | |
510 | ||
511 | * Many more ceph commands now output formatted information; select | |
512 | with '--format=<format>', where <format> can be 'json', 'json-pretty', | |
513 | 'xml', or 'xml-pretty'. | |
514 | ||
515 | * The 'ceph pg <pgid> ...' commands (like 'ceph pg <pgid> query') are | |
516 | deprecated in favor of 'ceph tell <pgid> ...'. This makes the | |
517 | distinction between 'ceph pg <command> <pgid>' and 'ceph pg <pgid> | |
518 | <command>' less awkward by making it clearer that the 'tell' | |
519 | commands are talking to the OSD serving the placement group, not the | |
520 | monitor. | |
521 | ||
522 | * The 'ceph --admin-daemon <path> <command ...>' used to accept the | |
523 | command and arguments as either a single string or as separate | |
524 | arguments. It will now only accept the command spread across | |
525 | multiple arguments. This means that any script which does something | |
526 | like:: | |
527 | ||
528 | ceph --admin-daemon /var/run/ceph/ceph-osd.0.asok 'config set debug_ms 1' | |
529 | ||
530 | needs to remove the quotes. Also, note that the above can now be | |
531 | shortened to:: | |
532 | ||
533 | ceph daemon osd.0 config set debug_ms 1 | |
534 | ||
535 | * The radosgw caps were inconsistently documented to be either 'mon = | |
536 | allow r' or 'mon = allow rw'. The 'mon = allow rw' is required for | |
537 | radosgw to create its own pools. All documentation has been updated | |
538 | accordingly. | |
539 | ||
540 | * The radosgw copy object operation may return extra progress info | |
541 | during the operation. At this point it will only happen when doing | |
542 | cross zone copy operations. The S3 response will now return extra | |
543 | <Progress> field under the <CopyResult> container. The Swift | |
544 | response will now send the progress as a json array. | |
545 | ||
546 | * In v0.66 and v0.65 the HASHPSPOOL pool flag was enabled by default | |
547 | for new pools, but has been disabled again until Linux kernel client | |
548 | support reaches more distributions and users. | |
549 | ||
550 | * ceph-osd now requires a max file descriptor limit (e.g., ``ulimit -n | |
551 | ...``) of at least | |
552 | filestore_wbthrottle_(xfs|btrfs)_inodes_hard_limit (5000 by default) | |
553 | in order to accommodate the new write back throttle system. On | |
554 | Ubuntu, upstart now sets the fd limit to 32k. On other platforms, | |
555 | the sysvinit script will set it to 32k by default (still | |
556 | overrideable via max_open_files). If this field has been customized | |
557 | in ceph.conf it should likely be adjusted upwards. | |
558 | ||
559 | Upgrading from v0.61 "Cuttlefish" | |
560 | --------------------------------- | |
561 | ||
562 | In addition to the above notes about upgrading from v0.66: | |
563 | ||
564 | * There has been a huge revamp of the 'ceph' command-line interface | |
565 | implementation. The ``ceph-common`` client library needs to be | |
566 | upgrade before ``ceph-mon`` is restarted in order to avoid problems | |
567 | using the CLI (the old ``ceph`` client utility cannot talk to the | |
568 | new ``ceph-mon``). | |
569 | ||
570 | * The CLI is now very careful about sending the 'status' one-liner | |
571 | output to stderr and command output to stdout. Scripts relying on | |
572 | output should take care. | |
573 | ||
574 | * The 'ceph osd tell ...' and 'ceph mon tell ...' commands are no | |
575 | longer supported. Any callers should use:: | |
576 | ||
577 | ceph tell osd.<id or *> ... | |
578 | ceph tell mon.<id or name or *> ... | |
579 | ||
580 | The 'ceph mds tell ...' command is still there, but will soon also | |
581 | transition to 'ceph tell mds.<id or name or \*> ...' | |
582 | ||
583 | * The 'ceph osd crush add ...' command used to take one of two forms:: | |
584 | ||
585 | ceph osd crush add 123 osd.123 <weight> <location ...> | |
586 | ceph osd crush add osd.123 <weight> <location ...> | |
587 | ||
588 | This is because the id and crush name are redundant. Now only the | |
589 | simple form is supported, where the osd name/id can either be a bare | |
590 | id (integer) or name (osd.<id>):: | |
591 | ||
592 | ceph osd crush add osd.123 <weight> <location ...> | |
593 | ceph osd crush add 123 <weight> <location ...> | |
594 | ||
595 | * There is now a maximum RADOS object size, configurable via 'osd max | |
596 | object size', defaulting to 100 GB. Note that this has no effect on | |
597 | RBD, CephFS, or radosgw, which all stripe over objects. If you are | |
598 | using librados and storing objects larger than that, you will need | |
599 | to adjust 'osd max object size', and should consider using smaller | |
600 | objects instead. | |
601 | ||
602 | * The 'osd min down {reporters|reports}' config options have been | |
603 | renamed to 'mon osd min down {reporters|reports}', and the | |
604 | documentation has been updated to reflect that these options apply | |
605 | to the monitors (who process failure reports) and not OSDs. If you | |
606 | have adjusted these settings, please update your ``ceph.conf`` | |
607 | accordingly. | |
608 | ||

758 | ===== | |
759 | ||
760 | Upgrading | |
761 | --------- | |
762 | ||
763 | * There is now a configurable maximum rados object size, defaulting to 100 GB. If you | |

813 | The 'ceph mds tell ...' command is still there, but will soon also | |
814 | transition to 'ceph tell mds.<id or name or \*> ...' | |
815 | ||
816 | * The 'ceph osd crush add ...' command used to take one of two forms:: | |
817 | ||
818 | ceph osd crush add 123 osd.123 <weight> <location ...> | |
819 | ceph osd crush add osd.123 <weight> <location ...> | |
820 | ||
821 | This is because the id and crush name are redundant. Now only the | |
822 | simple form is supported, where the osd name/id can either be a bare | |
823 | id (integer) or name (osd.<id>):: | |
824 | ||
825 | ceph osd crush add osd.123 <weight> <location ...> | |
826 | ceph osd crush add 123 <weight> <location ...> | |
827 | ||
828 | * There is now a maximum RADOS object size, configurable via 'osd max | |
829 | object size', defaulting to 100 GB. Note that this has no effect on | |
830 | RBD, CephFS, or radosgw, which all stripe over objects. | |

859 | v0.64 | |
860 | ===== | |
861 | ||
862 | Upgrading | |
863 | --------- | |
864 | ||
865 | * New pools now have the HASHPSPOOL flag set by default to provide | |
866 | better distribution over OSDs. Support for this feature was | |
867 | introduced in v0.59 and Linux kernel version v3.9. If you wish to | |
868 | access the cluster from an older kernel, set the 'osd pool default | |
869 | flag hashpspool = false' option in your ceph.conf prior to creating | |
870 | the cluster or creating new pools. Note that the presence of any | |
871 | pool in the cluster with the flag enabled will make the OSD require | |
872 | support from all clients. | |
873 | ||

902 | --------- | |
903 | ||
904 | * The 'osd min down {reporters|reports}' config options have been | |
905 | renamed to 'mon osd min down {reporters|reports}', and the | |
906 | documentation has been updated to reflect that these options apply | |
907 | to the monitors (who process failure reports) and not OSDs. If you | |
908 | have adjusted these settings, please update your ``ceph.conf`` | |
909 | accordingly. | |
