Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I've tried switching to linux many times before and each time came up to a problem and ended up giving up. This time I hope things are different.

I have a home server: P8Z77, 1xSSD (with Ubuntu 14.04 desktop currently installed), 2x1TB WD red hdd's, processor is an i5 from a couple of years back.

I have just installed Ubuntu so there's pretty much nothing but the basics on there. My goal has been to set up the 2 1TB drives in raid 1 and use that as a backup/web server/email server/home cloud etc.

To set up the RAID 1 I have followed the following guide: http://www.mysolutions.it/tutorial-mdadm-software-raid-ubuntu-debian-systems/#prepare-hard-drives

I'm stuck on point 2 - assembly. When I type in the command sudo mdadm --assemble --scan I get the output:

mdadm: No arrays found in config file or automatically.

Then I do :

cat /proc/mdstat

Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid1 sdc[1] sdb[0] 976762496 blocks [2/2] [UU]

unused devices:

Then : sudo mdadm --assemble /dev/md0 /dev/sdb /dev/sdc, the result is :

mdadm: /dev/sdb is busy - skipping mdadm: /dev/sdc is busy - skipping

Any help would be greatly appreciated!
