I have a running Raid1 with the mingo patches on the 2.2.14 kernel. I
got everything working, so I decided to turn off the machine and remove
one of the disks. I deleted the contents of the disk one, and then I
restarted the machine. It successfully started in degraded mode. I am running
root raid. I then took the removed disk, and I recreated the partitions on it.
I tried sticking it back in and doing a raidhotadd, but it complains.
everest:~# raidhotadd /dev/md5 /dev/hda5
trying to hot-add hda5 to md5 ...
/dev/md5: can not hot-add disk: disk busy!
everest:~# raidhotadd /dev/md6 /dev/hda6
trying to hot-add hda6 to md6 ...
/dev/md6: can not hot-add disk: disk busy!
Here is a snippet of the /etc/raidtab.
raiddev /dev/md5

nr-raid-disks 2
nr-spare-disks 0
