Ceph Restore Failure

[Cayuga]

I've done a lot of restores to both Ceph and local storage with 2.3. But, this morning I went to do a restore and got this error. Does anyone know how to get around it (I tried with both the most recent and the previous backups of this VM and got the same error):

I uploaded a fix to the pvetest repository. Please can you test with:

# wget ftp://download1.proxmox.com/debian/...inary-amd64/libpve-storage-perl_2.3-7_all.deb
# dpkg -i libpve-storage-perl_2.3-7_all.deb

Different error (I tried with the two most recent backups for this VM):

How did you create those rbd volumes? Using the pve GUI?

 

[Cayuga]

No, I created these back in pve 2.2 using "rbd import" of a raw disk.

 

[dietmar]

Please can you test with the following package:

# wget ftp://download.proxmox.com/debian/dists/squeeze/pvetest/binary-amd64/pve-qemu-kvm_1.4-9_amd64.deb
# dpkg -i pve-qemu-kvm_1.4-9_amd64.deb

Looks like the original problem:

Looks like the original problem:

You need to install both new packages.

 

[Cayuga]

Dietmar,

You are absolutely correct. When I installed both new packages the restore worked perfectly and the restored VM just booted successfully.

THANKS!
