Re: Status of CLVM?
Yes, because current snapshot is really Copy raw-formatted LVM volume to qcow2 file on secondary storage. So there is no real LVM snapshot, and if there were, it wouldn't be copied internally.

I'm thinking clustered filesystems such as GFS or Ocfs, but afraid of the penalty performance. Regards, Lucian -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro
Re: Status of CLVM?
You'd create a sharedmountpoint style primary storage, which would host qcow2 files. You can do this via iscsi, fibrechannel, or any other SAN tech.

Hi Marcus! This would work with 1 hypervisor, but with 2+ you need a cluster-aware filesystem. Recommendations? Lucian -- Sent from the Delta quadrant using Borg technology! Nux! www.nux.ro

You could use ocfs. - Chris Sent from my iPhone On 09 Jan 2014, at 00:59, Nux! n...@li.nux.ro wrote: On 08.01.2014 22:50, Marcus Sorensen wrote: You'd create a sharedmountpoint style primary storage, which would host qcow2 files.
