Description Juergen Maniera 2006-10-11 09:46:21 EDT
Description of problem:

If you reboot a System using LVM with an active Snapshot for a partition this
partition will not be readable at reboot any more :-(
As a workaround I had to add the following line into rc.sysinit
  modprobe dm_snapshot

before the LVM initialization starts
# LVM2 initialization

But maybe there is a more elegant way?

Version-Release number of selected component (if applicable):
Linux version 2.6.9-42.0.3.ELsmp (brewbuilder@hs20-bc1-7.build.redhat.com) (gcc
version 3.4.6 20060404 (Red Hat 3.4.6-3)) #1 SMP Mon Sep 25 17:28:02 EDT 2006

How reproducible:

see above

Thank you and regards
 Juergen Maniera

What is the error message you get?
Comment 2 Juergen Maniera 2006-10-13 08:27:20 EDT
Sorry but I hat no time to note it, because this bug occured on a central server
I had to get running asap :-( But /dev/mapper/vg-... could not be mounted,
because there was no valid file system found.
