Hi,
I use LVM on Debian Wheezy, kernel 3.2.0-4-amd64, with several dozens of
LVs.
Every attempt of mounting any of these LVs says : can't read superblock
I can't imagine than each of all theses LVs were corrupted at the same time.
There should be a common problem for that. But which one ??? FYI I'm
using LVM -on-DRBD-on-LVM.
DBRD seems to be fine.

There was no error about that in the system logs.
Any idea about that ?
