LVM mounting problems
Hi all,
I needed to expand my Debian Wheezy system by adding a 1 TB drive and
decided to switch over to LVM2 in the process. I rolled up my old 160 GB
drive into the 1 TB drive and called the whole thing "bigdisk" and
chopped the drive into 3 logical volumes. Everything seemed to work
until I started to try mounting the logical volumes. On boot up with the
fstab file shown below, the system gets a whole bunch of mod-probe
errors and finally drops into the maintenance mode. If I go in and # out
the 3 lines shown the boot goes as normal. My setup is:

The last 3 lines are the troublemakers.
/dev contains devices dm-0. dm-1 and dm-2 plus subdirectory mapper.
Mapper contains soft links bigdisk-backuppc, bigdisk-general and
bigdisk-extra to dm-0, dm-1 and dm-2 respectively.
Can anyone spot anything wrong?
Thanks in advance
