#0 lore raw

I am using LVM 0.9.1 beta 4 on Linux 2.4.1 with Reiserfs.

Snapshots created when the filesystem is active cannot be mounted. If I `umount' the filesystem before creating the snapshot, all is well.

I searched the mailing list archives and found a thread that dealt with this problem on Linux 2.4.0 by applying a patch that flushed the buffers before creating the snapshot:

http://lists.sistina.com/pipermail/linux-lvm/2000-December/005512.html

This is clearly the problem I'm seeing.

Is there a comparable patch for 2.4.1?

Will the fix become "standard" in 2.4.2
so that patching is no longer necessary?

Try the PATCHES/linux-2.4.0-test10-VFS-lock.patch in the latest release, it should apply ok.

At least the write_super_lockfs super_operations _is_ already in 2.4.1.

Of course it doesn't work. We've performed a software upgrade.

OK, we'll make a new patch for the next beta release (due out in the next couple of days).
