[ovirt-users] Re: oVirt Open Source Backup solution?
Derek,
That's risky.
Just read lock the DB, create the lvm snapshot and release the lock.
Otherwise you risk a transaction to be interrupted.

Yet another reason to do it from inside the VM.
What I do (on systems that have a running database) is to run a "flush"
operation to sync the database to disk, and then from within the flush
operation I create an LVM snapshot, and then I backup off the snapshot.
If I'm not running a database, then I just create the snapshot directly.
