[Gluster-users] Snapshot auto-delete unmount problem

Can you give us more logs on this issue. Also by any chance did somebody
unmount the lv's in any cases ?

[Gluster-users] Snapshot auto-delete unmount problem

Here is the glusterd.log file as it has just happened with a manual removal
of a snapshot.
The lvs exist even after the snapshot gets removed. I'm also running samba
on these with shadowcopy.

Thanks

*Gary Lloyd*

[Gluster-users] Snapshot auto-delete unmount problem

Incase anyone is interested this issue was caused by turning on brick
multiplexing.

Switching it off made the problem go away...
