Hello Dietmar ,

It seems that iscsi layer works but lvm does not.

   Volume group "vg4" not found
TASK ERROR: can't activate LV '/dev/vg4/vm-6001-disk-1': Cannot process 
volume group vg4

As soon as I remove VM that has image in zpool and reboot hostst , 
everything regarding iscsi-target-multipath works like before w/o any 
data loss or something like that

Thank you in adavnce

/srdačan pozdrav / best regards/
