Hi All, I posted last week about setting up a USB as a backup drive which I successfully set up. I was able to do one VM backup and it seemed to be working fine. I then tried to backup another VM and I believe something went wrong. Ever since then, the nightly backups are failing.
Can someone please tell me what I need to do to get this backup working again? I'm new to proxmox and do not know a lot of commands. So I am hoping there are some commands to be able to correct whatever is happening.
Please see log files below. - Thanks!

remove the logical volume manually.

Logical volume "vzsnap-ourserver-0" already exists in volume group "pve"
Code: 
lvremove /dev/pve/vzsnap-ourserver-0
 
When I run that command I get this error.....

Code: 
  /dev/dm-2: read failed after 0 of 4096 at 0: Input/output error

and when I look in that directory, I do not see that file, etc. Only data, root and swap is in that directory.
 
run 'lvdisplay'
 
I get this after running that command...

Tried that as well and got this... even though I see the file in the directory.

Code: 
device-mapper: remove ioctl failed: No such device or address
Command failed
 
@dietmar
The output was this...

I apologize that I do not know a lot of the line commands for proxmox. Can you please tell me what I would need to do in order to get this backup working?
Thanks
 
I tried both of those commands and got this...

Code: 
device-mapper: remove ioctl failed: Device or resource busy
Command failed

Anything else I can try or do?
