I have a server that was running Centos 6. It's been humming along for a few years and I have been backing up data off it on regular basis. All of sudden, and after a reboot, it came up in read-only mode. I think one of the folders failed to back up properly, and I would like to access the data. Here's what I did:
Got a new hard drive installed on the system.
Installed Ubuntu 15.04 Desktop on it.
Booted up from the new drive.
When I do:
It tells me that I have two drives, partitioned as follows:
sdb ----- sdb1 459.8 G ----- sdb2 8 K ----- sdb3 6 G sda ----- sda1 102 M ----- sda2 649 G
sdb is the new boot drive sda is the old boot drive
I can mount sda1 fine
When I try to mount sda2, I get the following error message:
unknown filesystem type 'LVM2_member'
Any idea what I can do to get to the data on /dev/sda2?
