Yes, Thanks!
Results are:
oak:~# mdadm -S /dev/md0
oak:~# mdadm -A /dev/md0 -f /dev/sd[abcd]1 /dev/hd[eg]1
mdadm: forcing event count in /dev/sda1(0) from 1271893 upto 2816178
mdadm: /dev/md0 has been started with 4 drives (out of 5) and 1 spare.
oak:~# cat /proc/mdstat
Personalities : [raid5]
md0 : active raid5 sda1[0] hde1[5] sdd1[3] sdc1[2] sdb1[1]

Now... After this is through rebuilding, I need to replace the failed
drive. (Creating one partition and setting it to type 0xFD (Linux raid
autodetect)
What's the best way to get this in service with one drive as a spare?
Can I convert my current spare (/dev/hde1) to a regular disk and add
the new disk as a spare?
Or should I add the new disk as an active drive and if so, will it be
rebuilt and the spare (/dev/hde1) be relegated back as a spare?
thanks again,
hank
