Old root pool spooks through the system

Apps and Virtualization
1

I am currently trying TrueNAS on an old computer and first named the pool “Test” and at some point I wanted to rename this to ‘tank’ as that seems to be the convention. So I deleted the old pool (Storage → Export/Disconnect → Delete Pool), and created a “tank” pool. This seems to have worked. So far so good.

Now as I said I am trying different things, and one of these is installing the “automatic-ripping-tool” App. Now I am getting this error notification during the deployment:

virt.global.setup emits [EFAULT] Failed to create dataset: Pool Test not found

I am assuming that somehow the deletion of the Test pool was not throughough. Of course a solution at this stage would be to wipe the system and start from scratch. But if I had more on the system this would not be a solution so I thought this may be useful as a bug report.

The full log is:

Try go to Apps → Configuration and see if old pool Is still selected. In case just swap It to the new

This settinng was unfortunately already set to tank.

Curiously, this error message may in fact be unrleated to this app because I got it to work after all: In the log it complained about access and I realized that I had to give the apps users ownership over its config/log/etc. directories. I got the app to start now

Maybe there’s a similar setting to the app pool for virtual machines.
