Getting the following error when the VM tries to autostart after reboot:
Code: 
kvm: -drive file=/dev/zvol/ssd/vm-101-disk-0,if=none,id=drive-scsi0,discard=on,format=raw,cache=none,aio=io_uring,detect-zeroes=unmap: Could not open '/dev/zvol/ssd/vm-101-disk-0': Unknown error 512
TASK ERROR: start failed: QEMU exited with code 1

After I log into the box, I can usually start the VM manually (after some time).

pveversion -v shows:

zfs storage seems to be finished before the QEMU start error. Here are some relevant log entries:

What's interesting is that it says "Testing 1 zvol links". But when I run zvol_wait after everything has stabilized, it says 3 instead of 1:

Code: 
# zvol_wait
Testing 3 zvol links
All zvol links are now present.
