Breaking a mirrored drive
______________________________________________________________________
Is there a way in Linux to break a mirror, and then use the drive that

was broken for some new partition (example: /home). FC3 and FC4. I am
running out of space and I am finding the RAID 1 is no longer desired.

You can use 'mdadm --fail ...', then 'mdadm --remove ...' to take it

out of the raid which will continue working fine >>with only a single
member. Be sure to change the partition type when you re-use it so the
system won't try to auto-detect and map it back in when you boot up.

This worked! One more question if I reboot I guess it will find the new
device and begin rebuilding the partition. So how do I change the
partition type, and should I change it to the main drive /dev/sda1 or
the second drive /dev/sdb1 (which has been removed). (fdisk?)
