Hi,

Before trying out, I want to understand how glusterfs will react for below scenario.

Please help me.

Let consider I have two host hostA and hostB

I have setup replica volume on hostA and hostB. (consider as storage domain for DATA in ovirt).

I have configure data domain mount command with backup server option (backup-volfile-server) as hostB (I mean main server as hostA and backup as hostB)

1> As I understood, VDSM execute mount command on both hostA and hostB.(for creating data domain)

2> That mean, HostB glusterFS CLIENT will communicate with main server (hostA).

(Please correct me if I am wrong here.)

3> Let say HostA got down (say shutdown, power off scenario)

4> Due to backup option I will have data domain available on HostB.

(Now glusterFS CLIENT on HostB will start communicating with HostB GlusterFS SERVER).

5> Now let say HostA comes up.

6> Will it sync all data from HostB to HostA glusterFS server ?

(as per doc, yes, i not tried yet, want to confirm my understanding)

7> Will glusterFS CLIENT on HostB start communicate with main server (HostA) ?

Please let me know, I am new to glusterFS.

Thanks,

~Rohit
