December 24, 20214 yr 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.

Hard to say since the diagnostics are from after the reboot. 46 minutes ago, hardw1red said: While i tried to do that with the parity disk i am now getting an error next to the disk saying "Parity is invalid". 46 minutes ago, hardw1red said: Is this something temporary until it rebuilds the data?

December 24, 20214 yr Author Operations tab says "Array Starting - Mounting disks..." The counters have not changed in a while. Edited December 24, 20214 yr by hardw1red
December 24, 20214 yr Author The counters are definitely not moving, what am i supposed to do? My data is still not accessible.

Hard to say since the diagnostics are from after the reboot. 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.

January 11, 20224 yr Author Just marking this solved, used the 2 ports out of the 4 for said controller and all issues went away.
