Error exporting/disconnecting pools on TrueNAS 12.0

Description

I'm having problems exporting/disconnecting pools on TrueNAS 12.0. Basically, I can't do it.

This is what I first did:
1. Under Storage -> Pools I select Add and then "Create new pool" and click "CREATE POOL".
2. In the Pool Manager I gave the new pool a unique name, added two disks (mirror raid), and added both disks as Data VDevs. I then clicked "CREATE".
3. The pool was created and I can see it under Storage -> Pools.
4. Under Storage -> Pools I clicked the settings icon for my new pool, and selected "Export/Disconnect".
5. I got a pop-up message saying "Error exporting/disconnecting pool. no path specified" and when I clicked "More info..." I got this:

After asking for help on

https://www.truenas.com/community/threads/error-exporting-disconnecting-pools-on-truenas-12-0.90452/

I've saved the config, updated to 12.0-U1.1, restored the config, and I still can't export/disconnect.

After moving the System Dataset to another pool, now when I try to export/disconnect any pool I get he Error exporting/disconnecting pool." error message popup, and now the trace is much longer than before:

I also see this in /var/log/middlewared.log :

I've tried exporting/disconnecting on all my pools (both online and offline pools), but I get the same error for all of them.

I'm running out of space on my old pools (I'm way above 80%) and urgently need to rearrange my disks/pools but right now I'm stuck due to this. So for me the impact is critical...

Glad to hear it works. Thank you for checking it out.

Hi Waqar, now everything seems to work. Changing

makes the export/disconnect pop-up appear instead of an error and a trace, and the pop-up warns about service dependencies relevant for the pool. I'll try tomorrow to actually go through with an export/disconnect and see what happens. If I encounter any problems I'll report them here.

Again, thanks!

can you please confirm if it's an issue now ? Thank you

Yes Waqar tried it again, and unfortunately it makes things worse.

As far as I can see, the only difference is the keyword await on line 1336. Without await, exporting/disconnecting works. With await, exporting/disconnecting no longer works and instead gives this error when I click "More info..." in the "Error exporting/disconnecting pool. no path specified" pop up window:
