[Gluster-users] Failed snapshot clone leaving undeletable orphaned volume on a single peer

Thanks D for the confirmation. I understand that is how it would have 
happened, but we are still not sure why it would create the directory 
only on s0 and not on others. Having said that, it is possible for it to 
be only on s0 and not on others till s0 was restarted. So after 58 hours 
of the repo being created, when glusterd was first restarted, that is 
when it would have passed the volume's info to the other nodes during 
handshake. Post this, every time you bring down glusterd on s0 and 
delete the repo, it would get it back from other nodes in the cluster, 
who now would have the repo. That is the only scenario in which we would 
see the behaviour in which the volume was initially present on s0 but is 
now present on other nodes.

We will keep you updated as and when we find the reason behind it 
creating the volume in s0 only. Thanks.

Regards,
Avra
