ZFS dataset empty after reboot

[alex3025]

Hello, I've updated to Proxmox 8.0.3 some days ago and yesterday after rebooting the server using the reboot command, one of my zfs datasets is now empty (the other dataset on the same pool are fine).

NAME               USED  AVAIL  REFER  MOUNTPOINT 
ssd-raid/storage   705G   732G   704G  /mnt/ssd-raid/storage

It seems that the files are still there but I cannot access them, the mountpoint directory is empty.

If I try to unmount that folder I get:

root@proxmox:/mnt/ssd-raid# zfs unmount -f ssd-raid/storage 
cannot unmount '/mnt/ssd-raid/storage': unmount failed

And if I try to mount it:

root@proxmox:/mnt/ssd-raid# zfs mount ssd-raid/storage
cannot mount 'ssd-raid/storage': filesystem already mounted

Now, I have disabled the auto mount of the dataset with zfs set canmount=noauto ssd-raid/storage and then restarted the server.
After mounting the dataset manually with zfs mount ssd-raid/storage, all my files where there again.

Is this an issue with the new Proxmox version? It never happened before...
