|

|
|
Run an rbd-mirror daemon to sync rbd images between clusters.
|
||
|
|
|
||
|
|
This requires two clients (one from each cluster) on the same host
|
||
|
|
to connect with. The pool configuration should be adjusted by later
|
||
|
|
test scripts to include the remote client and cluster name. This task
|
||
|
|
just needs to know how to connect to the local cluster.
|
||
|
|
|
||
|
|
For example:
|
||
|
|
|
||
|
|
roles:
|
||
|
|
- [primary.mon.a, primary.osd.0, primary.osd.1, primary.osd.2]
|
||
|
|
- [secondary.mon.a, secondary.osd.0, secondary.osd.1, secondary.osd.2]
|
||
|
|
- [primary.client.mirror, secondary.client.mirror]
|
||
|
|
tasks:
|
||
|
|
- ceph:
|
||
|
|
cluster: primary
|
||
|
|
- ceph:
|
||
|
|
cluster: secondary
|
||
|
|
- rbd-mirror:
|
||
|
|
client: primary.client.mirror
|
||
|
|
|
||
|
|
To mirror back to the primary cluster as well, add another
|
||
|
|
rbd_mirror instance:
|
||
|
|
|
||
|
|
- rbd-mirror:
|
||
|
|
client: secondary.client.mirror
|
||
|
|
|
||
|
|
Possible options for this task are:
|
||
|
|
|
||
|
|
client: role - ceph client to connect as
|
||
|
|
valgrind: [--tool=<valgrind tool>] - none by default
|
||
|
|
coverage: bool - whether this run may be collecting coverage data
