Subject: consistent LVM snapshot of domUs from dom0
Date: Thu, 6 Dec 2007 16:48:51 +0100 (CET) [thread overview]
Message-ID: <alpine.LRH.0.9999.0712061622140.11416@linuxbox.linuxbox.cz> (raw)
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
