In setting things up, I marked one of the 'master' drives as 'failed-disk' in my raidtab so that I could copy the data from that disk onto the raid then raidhotadd it in once the data had been copied over and my system was running entirely on the raid. So, when I mkraid'd the array, the spare disk was used in liu of the failed disk as I would suspect. I copied over all my data to the raid, rebooted, partitioned the formerly 'failed-disk' properly, changed 'failed-disk' to 'raid-disk' in /etc/raidtab, and 'raidhotadd'd it back into the array. I expected the array to reconstruct on this disk and put the spare-disk back as a spare, but that's not the case. Now, the newly added disk seems to be the spare, and the 'slave' disk is still in the array (which makes for bad performance). How can I tell the array to replace the slave disk with the disk that I just added? I figure I could just unplug the slave and let it reconstruct, but that doesn't sit well with me.
