June 20Jun 20 Hello i had something weird happen with my server.On thursday, my plex db got corrupted and one my pool drives (that I use as a downlad_cache) got an error. I fixed both the db and the corruption (by running btfrs repair and clearing the error), however after rebooting one of my array drives became unmountable. The drive is 16TBI tried to repair it but it was stuck on phase onePhase 1 - find and verify superblock...bad primary superblock - bad magic number !!!attempting to find secondary superblock......found candidate secondary superblock...unable to verify superblock, continuing....found candidate secondary superblock...unable to verify superblock, continuing......found candidate secondary superblock...unable to verify superblock, continuing....found candidate secondary superblock...unable to verify superblock, continuing.......................... (dots repeating forever)One thing I noticed was that both the drives that got an issue were drives that were connected to my SAS, so I swapped the cables and I moved the array drive to a sata connecting directly to the motherboard, and then run the xfs_repair overnight (about 7 hours).When I woke up it was still stuck on that phase 1.I tried with gemini to see if it had any good ideas, but it was recommending the same things I did.is there any hope saving it or i should just give up?tower-diagnostics-20260620-1137.zip Edited June 20Jun 20 by ntebis
June 20Jun 20 Community Expert How are you running xfs_repair? If from the CLI post the command used.
June 20Jun 20 Author The overnight was via the GUI. I did try on the CLI with the -n -L flags but only for a few minutes. Gemini advised that Phase 1 shouldnt take longer than a couple of minutes so I followed that.
June 20Jun 20 Community Expert Solution When using the CLI you must use the correct md device, but if the result above was from the GUI, the filesystem appears to be damaged beyond repair, best bet is to use a file recovery app like UFS explorer, the free trial should show if it can recover the data.
June 20Jun 20 Author Ah yes i did try also with doing /dev/mdxxx and it was the same. I will try with UFS Explorer. I assume that I need to do it on my personal machine and cant be done in Unraid?Thank you for your help Edited June 20Jun 20 by ntebis
