Wrong Fs Type, Bad Option, Bad Superblock On /dev/md0

We don't have dmraid installed on our Linux images (Ubuntu 12.04 LTS / Alestic cloud image) so there's no possible conflict there. You've already got the dmsetup ls output but the ls will help clarify and link the dm-3, 5 & 6 from your second paste. It is possible to define metric spaces from pure topological concepts without the need to define a distance function? I cant help you further.

You'll need to ensure that there is enough room for the superblock at the end of the device. Hyper Derivative definition. No spare drives.

I checked /proc/mdstat and mdadm --detail /dev/md0 and both show that everything is fine with the newly created array. $ cat /proc/mdstat [..] md0 : active raid1 sdb4[1] sda4[0] 241095104 blocks X-ray confirms Iam spineless! However, I wonder since if I previously had RAID on this disk if there is existing room for the superblock at the front of the device. his comment is here mdadm: cannot open device /dev/sda: Device or resource busy mdadm: /dev/sda has wrong uuid.

Because your using a raid level 1 you can mount one of the drives and copy data off it without assembling the raid array. 1) Make a random folder 2) mount Why did the best potions master have greasy hair? That you were able to recreate the RAID set at all is extremely lucky, but that doesn't change the fundamental flaws in your deployment.
