How to add a existing disk in a new vm?

[arevirjz]

Hi everyone

Well i have a issue with my datacenter.

I have a datacenter with 6 nodes, every node have 2 VM with virtualdisks into a NAS storage.
the last weekend the node 3 have an issue and now is offline

i have the virtual disk (.qcow2) of these VM's in my storage (NAS) but i can't use to create a new VM with other ID
can i use these disk to create a new VM in another node?

what exactly do you want to achieve? recover the VM that is on the failed node? if so, and if it only has shared resources (disks on shared NAS, no local passthrough or other things) then you can just move the config file in /etc/pve from one node to another to recover it.

if you really only want to import the disk image, you can use "qm import-disk" or "qm create" (create new VM) or "qm set" (update existing VM config) and the 'import-from=VOLUMEID' parameter to a disk slot like scsi0:

qm create 600 --net0 virtio,bridge=vmbr0 --name vm600 --serial0 socket \ --boot order=scsi0 --scsihw virtio-scsi-pci --ostype l26 \ --scsi0 pvedir:0,import-from=/path/to/dir/vm600.raw
