Re: [linux-lvm] After power outtage my vg is gone



Klaus,

you probably need to update to LVM 1.0.1 rc4 to address this then
(You can get the LVM code from CVS at www.sistina.com).

I am not sure if you need to update the kernel part of LVM in Debian though.

Just compile the library and tools as described in LVMs INSTALL file and try.
If that finds your VG (which I hope ;-) and you still see other problems,
please either get the recent Alan Cox kernel (which is up to date IRT LVM)
*or* patch Linus kernel following the instructions in LVMs INSTALL and
PATCHES/README files.

Regards,
Heinz    -- The LVM Guy --
