PVE Integration + ZFS over iSCSI restore fail

[alexis.berindei]

Hello all!

We are using PBS since last week with PVE integration.
VM start fine on the iSCSI backend, cloning work too but when I tried to restore a backup (backup made from NFS backend storage and trying to restore to ZFS over ISCSI backend storage) i got an error message :

Zvol was created (and remove after the failed restore) but the LUN mapping (ACL ?) not.

possibly this issue: https://lists.proxmox.com/pipermail/pve-devel/2020-November/045966.html ? as a workaround, you could give the qemu default initiator access on your iscsi storage until the fix is applied.

Thank you for the anwser !

ACLs has been (temporary) disabled, now luns and ACL mapping are fine but I got another error:

you'd have to check with your iSCSI target on why that is.. or try restoring to NFS or some other storage, and then move it with "move disk"?

That working fine ! No error while the restore, move, and vm boot.
