Hello,

I am working on migrating to Unraid from truenas but when I go to create the pool and add all the devices, it just keeps loading and never finishes.

It seems to get stuck exporting the zpool again.

Here is the SAS card that I use: 42:00.0 Serial Attached SCSI controller: Broadcom / LSI SAS2308 PCI-Express Fusion-MPT SAS-2 (rev 05)

Don't see a reason for the pool not importing, does a manually import/export with the array stopped work:

zpool import main

zpool status

zpool export main

Import works perfectly. Status shows all drives online and zfs list shows all my vols. But even at command line when I go to export, it just hangs without even being able to Ctrl+C it. No error messages in dmesg show up.

If it hangs during export in the CLI it's not surprising that it also hangs with the GUI.

I do see some the pool has zvols, but that should not be a problem, I also have some.

Does the pool export with TrueNAS using the CLI? Note that TrueNAS doesn't export the pools on normal shutdown/reboot, so if that was already an issue, it would not be noticeable.

I was able to import and export the pool with no issues in truenas.

Also tried importing and exporting on proxmox with no issues.

Just to see what happens, I exported the pool from proxmox, made a VM with Unraid and passed through all the drives and still same behaviour... Same hang on export within the Unraid VM.

Never saw that before, you can see if there's something logged after an export from Unraid, post the output from:

tail -n 250 /proc/spl/kstat/zfs/dbgmsg
