Hello all! I had 4 drives in my array and 1 parity drive. I have 1 cache drive, and 1 unassigned drive thats just used in a VM. Today, I added a fifth drive to my array. But now disk 4 is giving me problems. It said “Unmountable: Unsupported or no file system” so I took it offline and ran xfs check with -L. Everything seemed ok, but when I tried to access files stored on that drive, they show up as missing. I stopped the array, took drive 4 off the array, restarted it in maintenance mode, and then stopped it to reassign drive 4. But it wants to data-rebuild and the estimate is 300 days. Would greatly appreciate help. Diagnostics attached. newhomeserver-diagnostics-20250525-1417.zip

I swapped the SATA cables and added a parity drive. All seems clear for the past few days. Thank you!

Happened again I'll replace cables today, see if that helps. Would you recommend adding a parity drive now? Or to fix the issue first. Or to copy everything to a new drive in case this one is failing? Sorry for noob questions. newhomeserver-diagnostics-20231021-1053.zip

Apologies. Attached. I just tried again and everything is working but it broke twice on me already in the past day lol. newhomeserver-diagnostics-20231020-1320.zip

I followed your advice JorgeB. It seemingly fixed the issue temporarily. However when I try to access the drive, it gives me errors a few hours later. And upon a restart it goes back to saying unmountable.

I manually updated to Unraid 6.12.4 and now 1 of my 2 drives are unmountable. I'm afraid of doing anything to lose my data. Diagnostics are attached. I would sincerely appreciate any help. Thank you! newhomeserver-diagnostics-20231018-1844.zip
