Building Out XenServer 6.5 with USB Boot and Software RAID 10
-
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
-
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 md0results in
mount: mount point /mnt/raid10 does not exist -
mkdir /mnt/raid10
-
@DustinB3403 what is in your mdadm.conf?
-
Can't find
md0 in /etc/fstab or /etc/mtab -

I added an entry into fstab. It may have a typo...
-
fstab
-
fstab corrected, entry reversed.
mount raid10 mount: /mnt/raid10 is not a block device -
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
-
@Romo Same response when reexamining the disks. this is for both
mount /mnt/raid10 && mount /dev/md10
-
mount /dev/md0 /mnt/raid10 ?
-
/dev/md0 not md10
-
Using RAID 10 in names anywhere is very confusing and hard to read. I think several of these issues are partially stemming just from poor naming conventions. Name mount points by purpose, not technology.
-
You can't mount /dev/md0, because according to the mdadm --examine --scan ouput, the array, is at /dev/md/0

Good eye, that was hard to see.
