Steve,
create your raid definition file /etc/raidtab with
# raid-1 configuration of device /dev/md1
raiddev /dev/md1
raid-level 1
nr-raid-disks 2
nr-spare-disks 0
device /dev/hda5
raid-disk 0
device /dev/hdc5
raid-disk 1
Then do a 'mkraid -f /etc/raidtab'. You will need the -f (force) option to
clean up your previous 'mke2fs /dev/hda5'. Create a file /etc/mdtab with
'mdcreate /etc/raidtab'. Do a 'mdadd -ar', which starts the raid set(s) from
/etc/mdtab (check out /proc/mdstat that the set is working). Then format
/dev/md1 with 'mke2fs /dev/md1'. After this, you can do the 'mount /dev/md1
/mnt/spare' and go on. Note that you have to stop the raid set(s) in
/etc/mdtab with 'mdstop -a' after unmounting. Add /dev/md1 as a mount
point for /usr to your /etc/fstab. Probably you have to add 'mdadd -ar'
and 'mdstop -a' to your system startup and stop scripts.
Hope this will help,
Thomas
