Re: new array not starting

If I try to start the array manually:

# mdadm --assemble --auto=yes  /dev/md2 /dev/hdc /dev/hdd /dev/hde
/dev/hdf /dev/hdg /dev/hdh /dev/hdi /dev/hdj
mdadm: cannot open device /dev/hdc: No such file or directory
mdadm: /dev/hdc has no superblock - assembly aborted

What's going on here? No superblock? Doesn't that get written when the
array is created?

Am I doing this right?

SATA disks? hdc? Duh!

This worked:

# mdadm --assemble --auto=yes  /dev/md2 /dev/sdc /dev/sdd /dev/sde
/dev/sdf /dev/sdg /dev/sdh /dev/sdi /dev/sdj
mdadm: /dev/md2 has been started with 8 drives.

However, I'm not sure why it didn't start automatically at boot. Do I
need to put it in /etc/mdadm.conf for it to star automatically? I
thought md start all arrays it found at a start up?
