TrueNAS and multipaths & Dashboard

I'm currently running FreeNAS 11.1-U7, and to be honest, due to bad, unexplained experiences with I believe it was 11.2 where the system would just halt and reboot for no reason that could be determined, I'm a 'bit' gunshy about upgrading (11.1-U7 has been ROCK SOLID). However, I'm experimenting with TrueNAS Core 12.0-U3 for the possibility of upgrading.

The first thing that I've found is it seems multipaths are flaky (or at least appear to be). On my 'test' system, I have 11 disks, six 6TB and five 4TB, all SAS with a dual expander backplane and dual SAS controllers on the server. All disks show up in Multipaths, but when I go to create a pool, not all of the multipaths show up. As you can see below, four of the 11 show up as their active 'singlepath' name. Any thoughts on this?

The other thing is on the dashboard. The 'System Information' is fine, but the 'CPU' and 'Memory' just sit there with the 'spinning wheels'. The systems been up for 18 minutes and the browser has been connected for 17 of those minutes, and it never stopped 'spinning' or populated the panes. I've rebooted the system a few times and tried different browsers, no change. Even after it had been up for a few days, it was the same. Any ideas?

Maybe something to do with the middleware... maybe try a restart (service middlewared restart) or look in the middleware logs /var/log/middleware.log

gmultipath list gives me the following, which matches up with the 'Multipaths' list in the UI:

I copied the middlewared.log off and skimmed through it, but nothing jumped out at me. I also tried restarting the middleware, but no effect (Wouldn't rebooting the machine accomplish the same end result?).

Not if there's a race condition... if something that's needed isn't yet started during boot, perhaps something was hung waiting for it, which the restart might have allowed a "try again" which wasn't happening automatically. Anyway, no-go, so bad luck on that attempt.

If there's nothing there in the system, at least we know why the GUI is missing things.

Perhaps going through dmesg will shed some light on it.

That makes sense.

Not sure I follow. What do you mean 'If there's nothing there in the system'? The list of disks/multipaths under 'Storage > Multipaths' matches the output from gmultipath list, aside from the obvious formatting differences.
