[PVE-User] ZFS iSCSI issues

I have setup ZFS over iSCSI and everything seemed to be working okay except
one of 6 vm's all of a sudden froze and does not boot up again error given

TASK ERROR: Could not find lu_name for zvol vm-104-disk-1 at
> /usr/share/perl5/PVE/Storage/ZFSPlugin.pm line 102

I have rebooted node and storage all other vm's come up, I can create new
vm's everything seems to be working except this one. I am unable to locate
any detailed logs (next project is to create a logstash+elastic search). My
relevant configs are below.

Any help would be most appreciated.

Thank You
