Re: Snapshot auto-delete unmount problem

[Gary Lloyd <g.lloyd@xxxxxxxxxxx>]

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

Switching it off made the problem go away...

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

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