Hello,
I Install a Ubuntu as a ZFS Storage and created two datasets in ZFS.
The first dataset from SATA 7200k disks and the second from the PCI-E SSD.

Code: 
#zfs list
NAME                     USED  AVAIL  REFER  MOUNTPOINT
ssd                     45,7G   384G    96K  /ssd
ssd/iscsi                 64K   384G    64K  -
tank                    45,7G  15,3T   140K  /tank
tank/iscsi                93K  15,3T    93K  -

I created two targets for this datasets in ietd.conf file
Code: 
Target iqn.2017-04.Store002:ssd
Lun 0 Path=/dev/ssd,Type=blockio

Target iqn.2017-04.Store002:tank
    Lun 0 Path=/dev/tank,Type=blockio
I create two Storage in my cluster
Code: 
zfs: Store-002.ZFS
    blocksize 16k
    iscsiprovider iet
    pool tank
    portal 192.168.250.192
    target iqn.2017-04.Store002:tank
    content images
    nowritecache 0
    sparse 0

zfs: Store-002.ZFS.SSD
    blocksize 16k
    iscsiprovider iet
    pool ssd
    portal 192.168.250.192
    target iqn.2017-04.Store002:ssd
    content images
    nowritecache 0
    sparse 0

After i created VM 1000003 on the Store-002.ZFS.
Then I migrated VM disk on the Store-002.ZFS.SSD
After that I cannot delete the old disk with error
"Could not find lu_name for zvol vm-1000003-disk-1 at /usr/share/perl5/PVE/Storage/ZFSPlugin.pm line 105. (500)"

The configuration in ietd.conf has very strange
Code: 
# cat /etc/iet/ietd.conf
Target iqn.2017-04.Store002:ssd
Lun 0 Path=/dev/ssd,Type=blockio

Target iqn.2017-04.Store002:tank
    Lun 0 Path=/dev/tank,Type=blockio
    Lun 1 Path=/dev/tank/vm-1000003-disk-1,Type=blockio
    Lun 2 Path=/dev/ssd/vm-1000003-disk-1,Type=blockio

What did I do wrong?
