[Xen-devel] consistent LVM snapshot of domUs from dom0

[Nikola Ciprich <ciprich@xxxxxxxxxxx>]

Hello,
I'd like to ask a question regarding LVM snapshots:
normally if You make a snapshot of mounted LVM partition, DM 
infrastructure handles putting fs into consistent state using VFS 
infrastructure. BUT, does it work even if I make snapshot of LV used by 
XEN? 
If not, I guess it should not be that hard to fix, I guess we just need to 
notify domU kernel to call needed VFS function to put fs into consistent 
state prior to creating snapshot.
Can somebody comment on it, eventually correct me if I'm wrong?
thanks a lot in advance
regards
nik
