I am having the same problem. Lol I use Plex, home assistant, Medusa, Sab NZBD, Couch, Transmission, Netdata, Deluge and Smb shares as well. I have about 40+ users that use my plex and it works just fine so it is the Guis Middleware 100%.I upgraded from 11.3 U5 to 12 from the UI update page. it took a long time, but came back eventually. Once up, everything appeared to be working normally (I also mainly utilize Plex and SMB shares) but the next day when i wanted to login to the GUI to change some stuff, the GUI became unbearably slow. Logging in took 2-4 minutes, sometimes switching between dashboard and any other page would take even longer or just time out. Had to roll back to 11.3 U5 for now
Use the bootloader to revert to 11.3I woke up to "Update... 66.67%... Installing base-os (1/3)"
So, after 8 hours of updating 11.3 U5 to 12... I'm beginning to think it is fibbing to me!
I'm not doing much on it, basically file backup, which I've already backed up. And I'd ticked through the upgrades painlessly on my iXsystems FreeNAS Mini for years without even thinking to look for a forum to commiserate on.
At this point, I'd just as soon reinstall from scratch, if that is possible.
I installed TrueNAS 12 from downloaded ISO image onto my 4 year old iXsystems FreeNAS Mini; it worked like a champ. conveniently, I'd never gotten around to configuring much on it - just plain old file sharing - so, restoring was easy. Now it flies, and I've setup a batch of plugins and VMs.Does a clean install and restore from 11.3 backup work?
Well I was not haveing any errors so last thing I did that night was upgrade all my pools to 12.0. I should have waited. Next day I logged in to do more work on the jails and BAM ui is all jacked up.Does a clean install and restore from 11.3 backup work?
