Yet another ZFS Over iSCSI issue.

[ColoredBytes]

Hello All,

I'm a little stuck on getting this to work. I'm using the freenas-api setup to connect the two. I have a connection it reads the space allotted for it. But when trying to deploy anything to it.

I get this error

create full clone of drive scsi0 (SR-ZFS:vm-200-disk-0)
Warning: volblocksize (4096) is less than the default minimum block size (16384).
To reduce wasted space a volblocksize of 16384 is recommended.
cannot create 'tank/promos-zfs-storage/vm-200-disk-0': parent is not a filesystem
TASK ERROR: storage migration failed: command '/usr/bin/ssh -o 'BatchMode=yes' -i /etc/pve/priv/zfs/10.42.81.125_id_rsa root@10.42.81.125 zfs create -s -b 4k -V 104857600k tank/promos-zfs-storage/vm-200-disk-0' failed: exit code 1

Some Clarification the store is a zvol that i made on truenas scale. as stated before it shows the connection and gives me the option to deploy. But i get that error feel like im missing a crucial step or this api does not work as it used to. Any help is appreciated.

While I am not a ZFS/iSCSI expert, I think providing your storage configuration as well as ZFS structure from TrueNAS will be helpful to those who are.

Additionally, since you are using a 3rd party plugin, reaching out to that party is a prudent step. Things may have changed either on backend (truenas) or frontend (pve) enough to render the plugin less usable than desired.

Good luck

Thanks for the reply. I just thought about that as I got the response.

# Portals
3    0.0.0.0:3260    Proxmox    NONE

# initiators
1    Allow all initiators    iscsi-cluser-share   
5    Allow all initiators    proxmox-zfs-storage

# Targets
proxmox-zfs-storage

Associated Targets & Extents are blank per the documentation.

That is for the Config of the share
the block device itself is just a a zvol on the root of the dataset as i was also having issues when it was behind the proxmox folder.

Hope this helps a little more.
