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:
