You could use ocfs.

Hi Marcus!

This would work with 1 hypervisor, but with 2+ you need a cluster-aware 
filesystem. Recommendations?

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.

Status of CLVM?

2014-01-08 Thread Nux!

Hi,

I've just watched Marcus Sorensen's presentation on CLVM on youtube and 
he was mentioning that migrating a VM with snapshots will make the 
snapshots disappear.

Can anyone testify if this is still the case?
Since at it, are there any alternative ways of using a multipathed 
iSCSI lun with Cloudstack (KVM)? I'm thinking clustered filesystems such 
as GFS or Ocfs, but afraid of the penalty performance.

Lucian
