I am having trouble mounting a LVM to extract a Proxmox virtual machines data. Any ideas on how I can mount it?

The data is on one of the two 2TB hard drives. I think they are RAID 1

root@rescue:~# mount /dev/sdd /mnt/
mount: block device /dev/sdd is write-protected, mounting read-only
NTFS signature is missing.
Failed to mount '/dev/sdd': Invalid argument
The device '/dev/sdd' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
root@rescue:~# mount /dev/sdd1 /mnt/
mount: unknown filesystem type 'linux_raid_member'

  • Could you add the output of: `pvs`, `vgs` and `lvs` ? – Mircea Vutcovici Sep 30 '15 at 02:50
  • Added. It never detects the 2TB hard drive which is where the data is located. I think they are RAID 1 – demo9928881 Sep 30 '15 at 02:52

    You appear to have overwritten your LVM PV with an attempt to create a software RAID. Be aware that whatever was on that volume is probably not recoverable, as the first thing that happens to a newly created software RAID array is to overwrite everything. It is time to go to your backups. If you haven't got backups, stop everything and seek help from a professional data recovery company. – Michael Hampton Sep 30 '15 at 03:01
  • Could you run `pvscan` and again those 3 commands? – Mircea Vutcovici Sep 30 '15 at 03:03
  • Same output. I'm not sure why this happened I just rebooted and the 2TB hard drive could no longer be detected – demo9928881 Sep 30 '15 at 03:13

    You should clone this disk before messing with it any further. That said, give this a shot afterward; https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Logical_Volume_Manager_Administration/mdatarecover.html. – Aaron Copley Sep 30 '15 at 03:19
