[SOLVED] Live restore fails with: "Cannot get 'write' permission without 'resize'"

[abma]

i've tried a live restore of a vm, but it failed:

new volume ID is 'cephrbd:vm-105-disk-0'
new volume ID is 'cephrbd:vm-105-disk-1'
new volume ID is 'cephrbd:vm-105-disk-2'
rescan volumes...
VM is locked (create)

An error occured during live-restore: start failed: QEMU exited with code 1

error before or during data restore, some or all disks were not completely restored. VM 105 state is NOT cleaned up.
TASK ERROR: live-restore failed

an idea whats wrong?

PVE 6.4-6
PBS 1.1-5

vm config:

agent: 1
boot: order=scsi0
cores: 2
memory: 2048
name: oldserver
net0: virtio=00:50:56:a2:83:9a,bridge=vmbr0,firewall=1

scsi2: cephrbd:vm-105-disk-2,size=10G
scsihw: virtio-scsi-pci

tablet: 1
vga: qxl
vmgenid: 563a5bcd-1784-40d0-89ae-6176ce0d5390

the normal restore works, so no big issue...

scsi0: cephrbd:vm-105-disk-0,discard=on,size=15363M

At the moment, due to limitations in QEMU, live-restore is not available for disks that are not aligned to 4MiB (corresponding the the chunk size of PBS). This may change in the future.

ok, thanks! i'll resize the disk then: the weird size was because it was an imported vm.
