Veeam Restore for Proxmox VE failed (No such file or directory)

There is currently a problem with the new Proxmox VE integration in Veeam, as the restore of virtual machine does not function. The problem is due to a certain setup of Proxmox VE with Ceph for which KRBD is used instead of the standard library.

Mistake

This problem is indicated by the following error message during the restore:

• 
  The restore fails after "Processing of restore parameters".

Logoutput:

07.10.2024 09:37:56 Error    np-debian-01 : kvm: -drive file=/dev/rbd-pve/882b57fb-575b-4e9f-88ad-415e67d78200/vm_nvme/vm-114-disk-0,if=none,id=drive-scsi0,format=raw,cache=none,aio=io_uring,detect-zeroes=on: Could not open '/dev/rbd-pve/882b57fb-575b-4e9f-88ad-415e67d78200/vm_nvme/vm-114-disk-0': No such file or directory

Troubleshooting

To correct the error, you have to perform the following steps:

• 
  In the Proxmox VE GUI, go to [Datacenter] --> [Storage]. After this, select your Ceph pool and remove the checkmark at [KRBD].
• 
  After executing the restore again, it runs successfully through. Last, the KRBD checkmark could be set again.
