After backup (or disk move) everything is back to normal immediately. Nothing except on TrueNAS log: every pve host request...

    severe performance regression on virtual disk migration for qcow2 on ZFS with 5.15.39-2-pve

Everything went ok (except lost of connectivity with ifupdown2, perhaps I forgot to read some release...
