Hi all,
I have a simple replicated volume with a replica count of 3. To ensure any file changes (create/delete/modify) are replicated to all bricks, I have this setting in my client configuration.
volume gv0-replicate-0
type cluster/replicate
subvolumes gv0-client-0 gv0-client-1 gv0-client-2
end-volume
And that works as expected. My question is how one could detect if this was not happening which could poise a severe problem with data consistency and replication. For example, those settings could be omitted from the client config and then the client will only write data to one brick and all kinds of terrible things will start happening. I have not found a way the gluster volume cli to detect when that kind of problem is occurring. For example gluster volume heal <volname> info does not detect this problem.
Is there any programmatic way to detect when this problem is occurring?
Thanks,
Joe
