Hi,

I wanted to get some data off a second disk, let me tell you what I did. (that didn't work).

The data I am looking for is under /etc/ on the second disk.

I looked in /dev for /dev/hda or hdb but there was nothing.

I found:
/dev/sda
/dev/sda1
/dev/sda2
/dev/sdb
/dev/sdb1
/dev/sdb2

So I guessed /dev/sdb /dev/sdb1 /dev/sdb2 was the second disk.

So I did:
mkdir /tmp/olddisksdb
mkdir /tmp/olddisksdb1
mkdir /tmp/olddisksdb2

Then I did
mount /dev/sdb /tmp/olddisksdb and got mount: you must specify the filesystem type
mount /dev/sdb1 /tmp/olddisksdb1 and got no feedback (good?)
mount /dev/sdb2 /tmp/olddisksdb2 and got mount: you must specify the filesystem type

If I do:
ls /tmp/olddisksdb - I get nothing.
ls /tmp/olddisksdb2 - I get nothing
ls /tmp/olddisksdb1 - I get:

config-2.6.18-128.el5 symvers-2.6.18-128.el5.gz
config-2.6.18-164.9.1.el5 symvers-2.6.18-164.9.1.el5.gz
grub System.map-2.6.18-128.el5

lost+found vmlinuz-2.6.18-164.9.1.el5

This is a CentOS box, any help greatly appreciated.

What is the output of fdisk -la?

/dev/sdb is the WHOLE disk: that gets you nothing because it shouldn't be mounted that way and that's OK. Note if 'fdisk -la' does not work just use 'fdisk -l /dev/sdb' or 'partx -l /dev/sdb'. What's interesting is the partition type of primary /dev/sdb2. Is it LVM by any chance?

Thanks for your help guys.

Points for unSpawn for the correct answer!
