Tried power cycling but nothing came of it. Will get to the server by the end of the week and update here. Appreciate the replies.

Hello, my array brought itself offline sometime today and a data drive is missing, where can I check the why? is the drive dead? I do not have physical access to the server atm. PFA the diag. Thanks unraid-diagnostics-20250426-1837.zip

That worked, thank you.

Edited my initial post with diagnostiscs.

Hello, as per the title two of my pool disks were unassigned after a reboot, one is my docker_appdata nvme and the other one is a download cache sata disk. Both devices show up under unassigned devices. Is it safe to reassign them to their respective positions with no risk of losing data or is there anything else I should do? Thanks. unraid-diagnostics-20250213-1013.zip

Appreciate the quick reply. For reference's sake, what would be the optimal way of doing this? Also, since the new Data drive used to be a Parity drive would it need to be Precleared again?

Hey, my setup has 2 parity drives, I want to reassign the smaller one as a data drive. Followed the below instructions : 1. Stop the array 2. Select Tools >> New Config >> Keep Pool assignments for ease 3. Unassign the smaller parity drive 4. Assign the drive from step 3 to a Data drive slot 5. Start the Array 6. Wait for the Format to complete At this point I am at step 4 and I'm facing the attached image. Do I continue with step 5? Thanks.

Just marking this solved, used the 2 ports out of the 4 for said controller and all issues went away.

Would it be possible this happening from a controller standpoint (these drives were connected on a ASM1062 Serial ATA Controller) cause i have checked the cabling thoroughly and it happened again during parity check. Update: After reading regarding SATA controllers and chips it seems the one i am currently using is a "switched" one if that is the right term, it's a 4-port with ports 3-4 attached to port 2 which (have not confirmed cause i dont know how) cause issues while trying to write simultaneously to any of these 3 interfaces (ports 2-3-4). Parity has been rebuilt and data drives are also in the process of being rebuilt, after that I will remove the drives from ports 3 & 4 and see if the problem reoccurs.

The counters are definitely not moving, what am i supposed to do? My data is still not accessible.

Operations tab says "Array Starting - Mounting disks..." The counters have not changed in a while.

Hello all, 2 of my drives were disabled while i was moving files between shares. 1 parity and 1 data drive. I followed the instructions to try and rebuild them on to themselves as per the manual (disable-stop array-remove from slot-start array-stop array-add back in place-start array), the first time i tried to stop the array the system stopped at "Unmounting disks" and i had to hard reset in order to have access again to the Array. After the reboot i followed the above procedure. While i tried to do that with the parity disk i am now getting an error next to the disk saying "Parity is invalid". Is this something temporary until it rebuilds the data? How can i check if the Disabled parity disk is actually rebuilding the data, the read/write speeds are 0. The data disk that was disabled (smaller than any of the 2 parity disks) is not mounted on the array. unraid-diagnostics-20211224-2116.zip edit: just realised i've posted in the wrong place, if possible to move the thread where it needs to be, please, go ahead.

I had 2 bad cables, worked with the third one. Appreciate the prompt replies, we can close this.

This is the file i am getting on the USB stick when i run diagnostics on the server as i have no web access due to the original problem, i can download and extract the file in the first post, i think windows messes up the extension of the file. ziiEeIZ9.zip

My bad, attached the correct file in the original post.
