patience.....

Yes Yes, you're too quick some times sir. I corrected it.

[DustinB3403]

So with the above 3 pictures and the Array missing.

I'd obviously have to rebuild the array, and remap items. Additionally, I'll have to recreate my "backup" USB (which isn't a huge deal)

@DustinB3403 can you run

mdadm --examine --scan

[scottalanmiller]

We need to find the missing array before we can do anything else. As @romo mentioned we need to scan and see if the array is out there somewhere.

Running

    mount md0

results in

   mount: mount point /mnt/raid10 does not exist

[scottalanmiller]

mkdir /mnt/raid10

[Romo]

@DustinB3403 what is in your mdadm.conf?

[DustinB3403]

Can't find

    md0 in /etc/fstab or /etc/mtab

Should not be there, right?

I added an entry into fstab. It may have a typo...

[DustinB3403]

fstab

[DustinB3403]

fstab corrected, entry reversed.

     mount raid10
mount: /mnt/raid10 is not a block device

[Romo]

Your could run

mdadm --examine --scan >> /etc/mdadm/mdadm.conf

To recreate the conf and see if it fixes the problem. /dev/md/0 should be a symbolic link to /dev/md0

[DustinB3403]

@Romo Same response when reexamining the disks. this is for both

mount /mnt/raid10 && mount /dev/md10

[dafyre]

mount /dev/md0 /mnt/raid10 ?
