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