Hi!

Thank you for spending time reading about the issue I experience at this very moment.

Currently I have an HP DL380 Gen9 server for Unraid, just some simple storage, nothing crazy.

I had a few power outage, and after the 2nd one I turned off the server mostly for safety reasons and also because I had no need for extra storage at that time. This situation have changed now, I turned the server back on (after about 250days or so), moved a few hundred GBs of files onto it and after 3 days it hit the date for the monthly parity check. I checked on to see how its doing and noticed its only doing parity check with about 3 MB/s. I stopped it, restarted the server and the parity speed went up to about 60 MB/s for a few minutes, then it gradually dropped down back to 3 MB/s. I tried to update Unraid, I've been lacking on this front for a while... but my "Update OS" page is completely empty.. not even a single letter displayed on it.

I'm at a complete loss, my parity speeds were up in the 150 MB/s range before and I can't seem to figure out the reason what went wrong in the machine or the install to make parity and the "Update OS" issue that I'm experiencing now.

I've uploaded the diagnostics zip, I don't even know where to look in it to find solutions.

Thank you for reading this!
Have a pleasant day!

No obvious issues logged, though you are using a RAID controller, which is not recommended. You can run the diskspeed container to see if all disks are performing normally.

Thank you for this recommendation, I made it run through all of the hdd-s but they seem rather well grouped to my eyes.

Yep that looks fine, did you also run the controller tests, just to confirm they are still fast when accessed all together?

I did i think, but it still look fine to me. I'll try to look around in Intelligent Provisioning maybe it switched from hba mode at some point. Im at a complete loss right now.

It does, if it's still slow during a parity check, there could be a compatibility issue between the RAID controller or its driver and the Unraid driver.
