I am currently running TrueNAS 25.10.4 so am current, and I had installed and had operational the Truenas ZFS storage plug, and it was running nicely.

Today I saw there were update to install from the repositories, and one was an update to the plug-in and I figured it was no big deal, boy was I wrong!

I have gone through the configs, even removed and reinstalled the plug-in, but it will not mount the storage. When update was installed it just locked up everything, so I ended up rebooting.

If I run the config scripts, it says I have version "TrueNAS Plugin v2.1.14 - Installed" so looks to be current.

If I run pvesm status I get this warning: Plugin "PVE::Storage::Custom::TrueNASPlugin" is implementing an older storage API, an upgrade is recommended

If I actually put in the storage.cfg entry and run pvesm status, I get:

Plugin "PVE::Storage::Custom::TrueNASPlugin" is implementing an older storage API, an upgrade is recommended

storage 'TNAS380G10-ZFS-1' does not exist

It was working with uppercase, but tried it in lowercase with no difference.

My iSCSI is logged in and available:

# iscsiadm -m session
tcp: [1] 10.3.0.50:3260,1 iqn.2026-5.org.tnas380g10.ctl:tnas380g10-iscsi-pve-1 (non-flash)

my entry in storage.cfg is as follows:

truenasplugin: TNAS380G10-ZFS-1
api_host 10.3.0.50
api_key [deleted for security]
api_insecure 1

dataset Fast_15k/Proxmox_iSCSI

As I had all my VM's using that storage, everything is down at the moment. Anyone have any ideas??
