Migrate VM from node v5 to node v6 failed

[nicolaspetitjean]

Hello there !
I'm running into a small problem : before cluster migration v5 to v6, I migrated all my vm on one node. Now all nodes are upgraded, I'd like to move back vms on node v6.
But I got an error :

qemu-img: /dev/stdout: error while converting raw: Could not resize file: Invalid argument
command 'qemu-img convert -f qcow2 -O raw /var/lib/vz/images/160/vm-160-disk-1.qcow2 /dev/stdout' failed: exit code 1
cannot import format raw+size into a file of format qcow2

The vm config :

agent: 1
boot: cdn
bootdisk: virtio0
cores: 1

What am I doing wrong ? Thank you !

Hi,
seems like you have an orphaned disk /var/lib/vz/images/160/vm-160-disk-1.qcow2 that's not present in the VM configuration. You should check its timestamp/contents and see if you can safely remove it (maybe it's just some leftover of an earlier operation). If you're in a hurry you can also simply rename it, so that it doesn't include the VM ID anymore, and check later.

Yep, you're right. I deleted it and now it works fine
