Oh hi Mike, Raid 1 you should be able to mount as it's native filesystem
for recovery in read-only mode. EG
mount -t ext2 -o /dev/sdb3 /mnt/recovery
You mentioned LVM. That's going to be your problem for now.
You need to make sure you have the lvm2 tools installed.
Try 'pvscan' it should list the physical volumes (aka partitions in this
case).
'vgchange -ay' should 'activate' all the volume groups.
Then if that's done you should now find you've got some logical volumes...
'lvscan' will tell you.
Then it's going to be something like...
mount -o ro -t ext2 /dev/VolumeGroup/LogicalVolume /mnt/recovery
Note that I use the -o ro to mount read-only as you're less likely to fsck
up the data.

Hi all
I am trying to get data off someones old machine that died and place it onto
a new machine for them. The old machine had two Western Digital IDE drives as
RAID1. I have inserted one of the drives into a new machine in place of the
CDROM drive and connected it's IDE cable up and it shows up as /dev/sdc
/dev/sdc
sdc1
sdc2
sdc3
sdc5
Both of the drives show the same info above. By trying mount I can see that
partition 2 is the swap, 1 is probably a /boot and the data that I wish to
retrieve is on either or both of 3 or 5. See "Try to mount the Partitions"
below.
I also used mdadm to get some detailed info on sdc5 (see below).
My problem is that I can't work out how to mount sdc3 (have tried -t ext3, -t
reiserfs, -t auto) or sdc5. The latter is probably the one I want. I gather
the partition table says it 'mdraid' and I need to change that?
I have two drives, and both give the same info. I just need to mount ONE of
them and copy the data off it. I don't want to try and setup the original
raid.
(PS: the machine I have one of them installed on is using mdraid and LVM)
Try to mount the Partitions
---------------------------
# mount -r /dev/sdc1 /mnt
mount: unknown filesystem type 'mdraid'
# mount -r /dev/sdc2 /mnt
/dev/sdc2 looks like swapspace - not mounted
mount: you must specify the filesystem type
# mount -r /dev/sdc3 /mnt
mount: you must specify the filesystem type
# mount -r /dev/sdc5 /mnt
mount: unknown filesystem type 'mdraid'
Use mdadm to examine these partitions
-------------------------------------
# /sbin/mdadm --examine /dev/sdc2
mdadm: No md superblock detected on /dev/sdc2 <-- as it's swap OK
# /sbin/mdadm --examine /dev/sdc3
mdadm: No md superblock detected on /dev/sdc3
# /sbin/mdadm --examine /dev/sdc5
/dev/sdc5:
