Re: [linux-lvm] Remount a LVM Vol after a system crash

["Heinz J . Mauelshagen" <mauelshagen@sistina.com>]

Christoph,

I assume that you are suffering from a PE missalignent flaw which was
in 0.9 Beta 7.

Please update to the recent LVM version available at www.sistina.com.
Follow the information in INSTALL and PATCHES/README to get your SuSE system
updated. You need to have the kernel source package and the gcc packages
installed in order to be able to do this.

Regards,
Heinz    -- The LVM Guy --
