Yes, but this is handled internally by LVM and ext3 when the snapshot is created. > (xfs has a xfs_freeze function that does just this) In fact I was just discussing this with an XFS developer and this is a source of problems for them because if you do xfs_freeze before doing the LVM snapshot it will deadlock.
