    Well it seems that 2 drives have failed which is par the course for my luck level. Looks like im just gonna have to switch to raid 6 in the future or use SSDs on raid 5 not sure exactly at least most of my photos where backed up on Google Photos.

    I was able to mount my other good array (Nyaruko.local:Saber) on Linux Mint but not the one that had a disk with bad sectors.


    sudo cat /proc/mdstat

    Greetings I found out that one of my Raid 5 array of 4, 3TB WD RED disks failed. OMV would not recognize the file system either but still showed the disks.

    I have never used mdadm until now but from what I have tried this command seemed to be the silver bullet for most people in a similar situation as me.

    Code
    sudo mdadm --assemble --scan --verbose --force

    And here is the output.

    Any guidance on how to either get the three disks to mount together so I can off load the data or rebuild and new disk back into it would be much appreciated. Thank you.
