October 20, 20241 yr Hello,tower-diagnostics-20241019-2100.zip While trying to upgrade a few of my HDD from 8tb to 14tb drives... in the span of 36h I had two disks fail... one a parity and the other an array disk... so... Im willing to accept that I have lost the data on the 2 data disks... not a huge lose IMO... but how do I recover from here? should I accept that the parity and the data disks are bad and replace them with a few untested disks that I have on hand? My plan was to rebuild a disk while a x2 precleared a new disk... This went without issue the one time... but here on the second attempt everything went tits up... I had a failed disk 6 52% into rebuilding the one disk... I restarted unraid and started rebuilding the 1 disk with a failed disk... 2% into the process I lost a parity drive... I would like to save one of the disks so that I dont lose 2 disks worth of data... but it would also be nice to know that if I replace the two disks, that I wont continue to have failed disks... to note... disk 4 was rebuilding... disk 6 failed first... rebooted and then the 2nd parity disk failed...
October 20, 20241 yr Author I would like to note that this is the first time that I have ever had more then one disk fail in the ten years that I have been running this software... never expected to have more then one HDD fail at a time... but hey... shit has to hit the fan once and a while... right?!?
October 20, 20241 yr Community Expert Parity2 issues looks more like a power/connection problem, you can try to check/replace cables and then force enable it to see if it can still emulate the disabled disks. -Tools -> New Config -> Retain current configuration: All -> Apply -Check all assignments and assign any missing disk(s) if needed -IMPORTANT - Check both "parity is already valid" and "maintenance mode" and start the array (note that the GUI will still show that data on parity disk(s) will be overwritten, this is normal as it doesn't account for the checkbox, but it won't be as long as it's checked) -Stop array -Unassign disks 4 and 6 -Start array (in normal mode now) and post new diags

October 20, 20241 yr Author Have a feeling I might have screwed myself here... after clearing the configs and before starting the array in maintenance mode. Disk 6 was a no show, while I could have assigned a new disk that I was preclearing, I left it out of the new config(that HDD no longer is showing as a disk that I could have assigned beyond the preclearing hdd) Currently the array shows that disk 4 is missing and that I no longer have a disk 6... Gotta feeling I am SOL...
October 20, 20241 yr Community Expert You need a disk6 assigned, if the old one isn't working it can be a new one, same size or larger than the old one. While not ideal, it may still work if you repeat the procedure with a new disk6
October 20, 20241 yr Community Expert Check filesystem on the emulated disks 4 and 6, run it without -n, and if it asks for -L use it.

October 20, 20241 yr Community Expert Sorry, forgot to mention, you need to first set the filesystem to xfs, with the array stopped click on each disk.
October 20, 20241 yr Author I went ahead and just adding the drives as new and will start the long task of rebuilding
October 23, 20241 yr Author Gonna rant for a little bit... while rebuilding/just adding blank disks that were precleared, unraid decided that it needed to 'rebuild' the disks and after babying the system running minimal dockers... at 80% complete, the OS decided to go MIA... zero disk activity, console MIA... restarted and started rebuilding again... FFS....
