Hey everyone,

I've been using unRAID for years now and never really had any issues. Updates have always gone smoothly.

However, I'm currently dealing with a problem where I can't update from version 7.2.4 without my server basically breaking. Whenever I update to 7.2.5, 7.2.6, or 7.3.0, the WebUI becomes incredibly laggy and unresponsive. I can't stop the array once it's running, and I can't reboot or shut down. Rebooting or shutting down via the console doesn't work either, so I end up having to do a hard reset using the physical power button on the machine.

On top of that, if I go to "Shares" and try to open one, the WebUI just loads endlessly and won't display any content. The shares are also not reachable with my PC e.g.

I currently have Docker and VMs disabled. If I turn them on, I can access some WebUIs (like Sonarr) to an extent, but then—sticking with Sonarr as an example—it suddenly shows 0 episodes for every single show.

The second I roll back to 7.2.4, everything works perfectly fine again.

Note: I have currently no Parity configured as I am waiting for the update issue to "be resolved" before mounting the Parity again. I have it not configured, because the Parity disk became disabled and I have to rebuild it again.
Second note: I had two Cache pools configured ("Cacheone" and "Cachetwo") and after updating to 7.3.0 "Cachetwo" showed errors. I have since removed the second Cache pool (it's a rather slow SSD I used for overnight backups of remote VPS servers).

I have attached the diagnostics and also S.M.A.R.T-Test-Results I did a couple of days ago.

Boot with a different flash drive, using a totally stock install, no key needed), and see if the GUI is still slow.

Sorry for the late reply. I currently have no different flash drive until next week when I can buy one.

In the meantime I rolled back to 7.2.4. Everything seems to work fine again (like always after a rollback), but I noticed a lot of errors in my log (see attached screenshot). I also noticed, that my Parity-rebuild is really slow, only about 20mb/s.

Could maybe this have to do something with "bricking" my server when updating?

There are issues with multiple devices, and I see you are using a controller with SATA port multiples. Those are not recommended and can cause a lot of issues. It could also be the reason for the unresponsive issues with newer versions due to kernel updates. I recommend replacing it with one from here:Recommended controllers for Unraid - Storage Devices and Controllers - Unraid

Thank you for the suggestion. I replaced my controller and the SATA cables with a recommended one -> still had errors -> I replaced the power cables for the drives and updated to the newest BIOS for my mainboard -> no more errors and the system is very stable and responsive even on 7.3.0. So either the power cables, the BIOS or a combination of those were the culprit. I am glad to be "online" again, as I have otherwise never had issues with unRAID.
