So, forget xfs_freeze." as i understand it, consistent copy is created when lvcreate is issued, not when snapshot volume is mounted - is this right ? if so, shouldn't filesystem also be frozen when a snapshot volume is created ? if it actually is done together with snapshot, does this mean that i really can forget about xfs_freeze and just create snapshots ? must i specify ro in mount options or is this optional ? -- Rich
