4 | rbd-mirror -- Ceph daemon for mirroring RBD images | |
5 | =================================================== | |
6 | ||
7 | .. program:: rbd-mirror | |
8 | ||
9 | Synopsis | |
10 | ======== | |
11 | ||
12 | | **rbd-mirror** | |
13 | ||
14 | ||
15 | Description | |
16 | =========== | |
17 | ||
18 | :program:`rbd-mirror` is a daemon for asynchronous mirroring of RADOS | |
19 | block device (rbd) images among Ceph clusters. It replays changes to | |
20 | images in remote clusters in a local cluster, for disaster recovery. | |
21 | ||
22 | It connects to remote clusters via the RADOS protocol, relying on | |
23 | default search paths to find ceph.conf files, monitor addresses and | |
24 | authentication information for them, i.e. ``/etc/ceph/$cluster.conf``, | |
25 | ``/etc/ceph/$cluster.keyring``, and | |
26 | ``/etc/ceph/$cluster.$name.keyring``, where ``$cluster`` is the | |
27 | human-friendly name of the cluster, and ``$name`` is the rados user to | |
28 | connect as, e.g. ``client.rbd-mirror``. | |
29 | ||
30 | ||
31 | Options | |
32 | ======= | |
33 | ||
34 | .. option:: -c ceph.conf, --conf=ceph.conf | |
35 | ||
36 | Use ``ceph.conf`` configuration file instead of the default | |
37 | ``/etc/ceph/ceph.conf`` to determine monitor addresses during startup. | |
38 | ||
39 | .. option:: -m monaddress[:port] | |
40 | ||
41 | Connect to specified monitor (instead of looking through ``ceph.conf``). | |
42 | ||
43 | .. option:: -i ID, --id ID | |
44 | ||
45 | Set the ID portion of name for rbd-mirror | |
46 | ||
47 | .. option:: -n TYPE.ID, --name TYPE.ID | |
48 | ||
49 | Set the rados user name for the gateway (eg. client.rbd-mirror) | |
50 | ||
51 | .. option:: --cluster NAME | |
52 | ||
53 | Set the cluster name (default: ceph) | |
54 | ||
55 | .. option:: -d | |
56 | ||
57 | Run in foreground, log to stderr | |
58 | ||
59 | .. option:: -f | |
60 | ||
61 | Run in foreground, log to usual location | |
62 | ||

65 | ============ | |
66 | ||
67 | :program:`rbd-mirror` is part of Ceph, a massively scalable, open-source, distributed | |
68 | storage system. Please refer to the Ceph documentation at http://ceph.com/docs for | |
69 | more information. | |
