[pve-devel] lvm snapshots performance ?

[Alexandre DERUMIER]

>>I doubt (seems technically impossible to me). 

Yes I think also that is not possible. 
So I'm not sure live migration can works, in a pool cannot be mount on 2 server at the same time.


>>Maybe it can work with one pool per volume, so that we can speedup snapshots. 
I have (fastly) read the doc, I think we need to associate a whole physical(s) disk(s) to a pool, 
so it's not easy.

Our kernel is based on RHEL6.2, so I guess we need to wait until ovz release a RHEL6.3 based version.

I doubt (seems technically impossible to me). 

Maybe it can work with one pool per volume, so that we can speedup snapshots.
