so this started a few weeks back with Jorge helping me recreate with a new config after i had more than one disk go wrong.

Seemed to be working ok for a while then back down again with a disk error.

I had not fully reinstalled back int he rack in case so i coudl take it back out

 

What i have done in the meantime is add a fan to my raid card in case that was causing any issues.

 

doesnt seem to have helped though.

 

so i lost disk 1 at some point. turned off array restarted with no  disk turned it back on then off added the disk etc and its readded each disk each time i have done it. 

 

One issue i was not happy about for some time was the 8tb Toshiba drives i have seeming to run very hot. so i decided to get some more 14tb elements and shuck them. same as my other 14tb drives that are in and seem to ahve been working fine for a while. 

 

so last week i lost disk 6. tried the normal approach of removing restart stop then add and rebuild. but it still gave me errors. 

perhaps it was actually a dead disk this time. 

 

so i bought the elements drives and added one today. 

 

since then i had a few errors show up on disk 9 which has not happened before now. 

 

but anyway. i added the new 14tb disk 6 assigned it and waited for it to rebuild. this time its saying unmountable wrong or no file syste,m, while its rebuilding. 

which from what i can see means the emulated data is bad. 

so its writing nothing useful to the disk to rebuild so the parity is good. which im not particularly fussed about. 

 

The rebuild is also going to take 253 days according to the little info box. so i assume im having another issue again. 

 

in the meantime i have the old 8tb disk i removed mounted using linux diskinternals and my disk 6 data all seems to be there. so the disk is not bad. its got to be either an issue with the (now fan driven) lsi card or the icydock thing which seems to be a generally crap piece of kit so i should probably remove that anyway. 

diags attached if anyone can give me any sort of advice or insight. 

 

I would really like to be able to read these myself to self diagnose. but im not sure entirely where to start with it. and im very tired after another day with this thing 

 

ill sleep and try again tomorrow. hopefully with some insight from you wonderful people. 

thanks in advance for the help. again.

Replace cables for parity and disk9, then post new diags after array start. Any power splitters in use?

new diags. im going to swap out the psu in an hour or so as i read somewhere else that it could possibly be psu degredation. im not sure how old the psu is. but it isnt new lets put it that way.

Still errors with parity, swap both cables with another disk to see where the issues follows.

 

 

power supply... i really hadnt even considered it. 
swapped for an antec 850W gold and its all back up and running. 9 hrs to rebuild. 

however i still have the unmountable wrong or no file system. nas1-diagnostics-20250402-1205.zip

No ATA errors so far, regarding the unmountable disk, check filesystem.

ok. do i need to allow it to finish rebuilding first? or should i pause/cancel and fix the filesystem first?

 

or just fix while its rebuilding?

sorry i just read through the page. its all there. il report back how i get on. 

 

I would recommend doing it before the rebuild.

other than the iso folder being cache only the fix appears to have worked well and the data is now rebuilding. 

so while it is possible that the addition of a fan to the lsi card helped in soem way it appears that the psu was degraded as replacing that has fixed all the connection issues. 

it must have been just on the edge of capability and then dipped below. 

Thanks again @JorgeB

final diagnostics after the rebuild has finished. Anything i should be worried about here?nas1-diagnostics-20250404-0602.zip

Looks fine, no ATA errors.
