Hi cephers,
I am wondering someone that familiar with function of rbd-mirror can
give me some hints.
There were 2 clusters site1 and site2. Both sites deployed by command
ceph-deploy.
And there are the steps of my test. With Ubuntu 14.04(kernel 3.19).
1.) On site1 ： Copy ceph.conf and ceph.client.admin.keyring to "local.conf"
"local.client.admin.keyring"
2.) On site2： Copy ceph.conf and ceph.client.admin.keyring to
"remote.conf" "remote.client.admin.keyring"
3.) Copy these files to each sites.
Boths site used command "ceph -s --cluster=local" (or remote) can get
result successfully.
4.) Both sites installed "rbd-mirror".
Start daemon "rbd-mirror" .
On site1：$sudo rbd-mirror -m 192.168.168.21:6789
On site2：$sudo rbd-mirror -m 192.168.168.22:6789
5.) Enable mirror mode "pool" of pool "rbd".
$rbd --cluster local mirror pool enable rbd pool
$rbd --cluster remote mirror pool enable rbd pool
6.)Peer setting：
$rbd --cluster local mirror pool peer add rbd client.admin@remote
$rbd --cluster remote mirror pool peer add rbd client.admin@local
Finally, I think I can create a rbd image and wait it sync to other site.
But nothing happed. And the log seems no error, only 2 messages.
---rbd mirror log-------
