i moved the data, formatted the drive, didnt rebuild it from parity, started is as a fresh drive and now it all works. i have two final questions though: 1) what do you think could've caused this and what do i do to prevent this in future? 2) when i run zpool status disk3 -v it shows me less info, compared to other disks1,2,4,5. why is that so? does this mean other disks need to be formatted too because they have some features disabled and only disk3 has them enabled since it is a "newly" installed disk?

ok here's the diagnostics that i downloaded after fresh system reboot and array start server-diagnostics-20250805-1402.zip

so what do you think i should do next? even after complete reformat and rebuild of the disk3 the movies folder is still not accessible. i cant just delete EVERYTHING worth of 60TB and re-acquire all the data. there must be another way somehow. all the files are accessible in disks.

i just finished scrubbing disk4 with this result so i think disk4 is healthy, right? i'm going to start moving data from disk3 to disk5 now and post an update afterwards.

does this definitely mean disk4 is healthy and only disk3 is corrupted? or do i need to run some additional commands to make sure disk4 is definitely healthy? what do i do now? do i start copying data from disk3 to other disks? and whats the next step after i copy that data? do i just remove the disk3 from array and keep using the server? idk how to properly REMOVE the drive from array, so far i've only ever added new drives to the server.

but i ran memtest for a long time with no issues. how can the ram be faulty? i am going to throw this disk3 away completely after this scrub is done. and i'll monitor disk4 too. in case it also starts acting up imma throw it too. i have 12th gen i3. is that risky too? its just the disk that is corrupted right? not the files. i mean moving data from disk3 to other disks wont damage them too, right?

so if i go into disk 3 and manually move all the files from it to another disk (1,2,4 or 5) will that fix the issue that i have? will i be able to access the movies folder afterwards? and two more questions: 1) how do i actually do that? from within the webui? or do i use plugins like unbalanced? 2) why are there no other errors anywhere? no notification in webui. no error in hdd smart data? etc.

i tried manually removing, clearing and re-adding disk3 and disk4 to the array rebuilding each one of them separately from parity. issue still persists. now i started scrub again and this is the current situation as of right now: I'm going to reboot system after scrub and post here again. i'm so confused at this point. how can everything inside share be accessible except one folder. and how can even that one folder still be accessible through individual disks? what is the problem with my server exactly? are the drives dying? are the cables faulty?

again. sorry for such a late reply. didnt have much time to do memtest, and since EVERYTHING else was working fine on my server i kept using it normally. so now i got time for that and ran memtest for about 17-ish hours. no errors. ram is fine. i did two separate 3-hour runs (4 passes) and then another longer with more passes that i waited for for about 10ish hours. so what is my next step now? how do i make the files re-appear inside the movies folder? or what do i even do to fix the issue of those random zpool errors.

what if i do parity check? maybe it can fix something? (but i only have one parity drive and two of the drives have those zpool errors) btw i already tried scrub and i thought it fixed the errors, but neither the movies folder has re-appeared nor the errors have disappeared completely (they were gone for a few hours and then i still got the errors)

any suggestions on how to get the content inside the movies folder back though? or do i have to do the memtest first ?

alright, will do 24 hours

sorry for a late reply. this is the diagnostics file attached. also how long do i need to run memtest to make sure ram is not an issue? server-diagnostics-20250628-2353.zip
