cscott Posted June 7, 2021 Share Posted June 7, 2021 Today I swapped out the motherboard, CPU and RAM in my server. Got everything back up and running, but noticed that two of my disks show the error "Unmountable: Not Mounted". Read though many post on these forums, but its still not working. Moved SATA cables around, no change. Please help. unraid-diagnostics-20210607-1355.zip Quote Link to comment
JorgeB Posted June 7, 2021 Share Posted June 7, 2021 https://wiki.unraid.net/Check_Disk_Filesystems#Checking_and_fixing_drives_in_the_webGui Fix filesystem on both disks, run it without -n or nothing will be done. Quote Link to comment
cscott Posted June 7, 2021 Author Share Posted June 7, 2021 This is the output. Quote Link to comment
cscott Posted June 7, 2021 Author Share Posted June 7, 2021 Is that going to delete my data? Quote Link to comment

trurl Posted June 7, 2021 Share Posted June 7, 2021 The -L option just deletes that log and not any of your data. Since Unraid already says the disk is unmountable, there is no way to mount it to replay the log. Quote Link to comment

I have changed all that hardware more than once without problems. What can you tell us about the old hardware, especially the disk controller? Quote Link to comment
cscott Posted June 7, 2021 Author Share Posted June 7, 2021 Dont think the disk controllers are any different. I did go from an Intel based setup to a AMD setup. So it didn't delete all my files.. it put them in the lost+found folder... do i have to sort through them manually? or is there an easier way to put all the files back where the go?

cscott Posted June 8, 2021 Author Share Posted June 8, 2021 No just the parity disks... Could I rebuild it with the parity disks? If so how? Quote Link to comment

Unfortunately parity can't help with filesystem corruption, it would rebuild the disks as they are now, but it's not normal to have severe corruption in two disks at the same time, you might have a hardware issue, like bad RAM.

Lots of ways to lose data that have nothing to do with failed disks, including user error. You must always have another copy of anything important and irreplaceable on another system or external.
