[PVE-User] LVM Rescue

[Gregor Burck]

Hi,

first: is is alowed to post an question here and the forum? Someone  
will be on both, other only here or there?

second:

I've trouble with an not started pve server, he've problems with his  
lvm storage.
 From a live System I could see the disks.

My question now is, could I copy them with dd to an external medium?
Like: 'dd if=/dev/pve/vm-102-disk-0 of=/mnt/USB/image.img bs=...'

The problem occure when I setup an NFS Backup Storage and made an  
reboot,... so there is now no vaild backup.

Thank for all little help,...

Gregor

allowed - yes (both are public forums)
encouraged - no - all of us here at proxmox read both and try to help out
- if you post to both that leads to double effort. Of course if you don't
  get an answer on either of both - you can/should try to reach out via the
  other medium (best with referencing the forum/mailinglist thread :)

The command looks ok - and if the disk contents are ok you should be
able to use the resulting image.img as raw image for the guest (name it
appropriately and put it in the right path in a configured storage)

OTOH - if the contents of the LV /dev/pve/vm-102-disk-0 have a problem
then copying it won't help - but it's probably the first thing I'd try in
that situation.

Hope that helps!
