LVM partition restore

[micfrip]

Hi,

After an failed upgrade, I had to reinstall my Proxmox server.

However, I have stored all my backups on the second drive (a LVM formated drive).

After reinstallation, I am not able to mount the second disk LVM partition anymore.
The usual commands "lvm lvscan" only shows the news partitions on the first drive.

Any help would be really appreciated.

Many thanks,


Michaël

Hi Michaël,
this looks like only one disk... where is the second (sdb) one?
Does "fdisk -l" show another disk?

Are both disk are visible in the bios?

And what's about your installation - because of the bash-completion-error.

Yes, there is a second disk :

Disk /dev/sdb: 2000.4 GB, 2000398934016 bytes81 heads, 63 sectors/track, 765633 cylinders, total 3907029168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xaa558907


   Device Boot      Start         End      Blocks   Id  System

But why this hdd don't appear with blkid?

 

[micfrip]

I think that was because I didn't unmount correctly the LVM partition.

Now the problem is solved : I have used Testdisk to retrieve my files. Everything is ok now.

Thank you !
