BS.  You are trying to mount a non-clean filesystem on a read-only

His LV is read-only because it's a snapshot. That means he took a snapshot of a unclean ext3 filesystem, and can't mount it because ext3 wants to clean it up during the mount and cannot do so.


What is the recommended procedure for doing snapshots of journalling filesystems? Do the filesystems have to support snapshots directly and "quiesce" themselves while the snapshot is being created?
