Description Justin Hahn 2003-08-22 15:55:34 EDT

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-us) AppleWebKit/85 (KHTML, like Gecko) 
Safari/85

Description of problem:
The Redhat kernel is missing the LVM VFS-Lock patch which prevents snapshots of journalled 
filesystems from being mountable. One of the major advantages to LVM is the ability to do 
snapshots (for backups among other things.)

The VFS-Lock patch is well tested and used widely. It is in consideration for 2.4 inclusion (though 
Marcelo may have some objections.)


Version-Release number of selected component (if applicable):
2.4.20-20.7

How reproducible:
Always

Steps to Reproduce:
1. Create an LVM vg
2. Create an LVM pv
3. Create an ext3 fs on said PV
4. Snapshot the PV
5. Try to mount the snapshot

Actual Results:  mount complains the filesystem is in a bad state and cannot be mounted. Since the 
snapshot is r/o at the volume level we're SOL

Expected Results:  file system should mount it without complaint

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
