Not sure what you mean, as I don't use mdadm... There is a BIOS level
utility you access at boot time to add and remove drives from the array,
which you can do with a failed drive after it has cooled off and started
working, if you only have one or two (after the first fails, the hot
spare replaces it, when the second fails, the RAID5 still works but in
degraded mode - it's when the third fails that problems set in, because
the other two have been marked bad and stay that way until you release
them and reassign them). It may be possible to do that with the tw_cli
utility, but I wouldn't know how as I never needed to do that to a
running system. Since it was shut away in a closet (hence the bad
ventilation) and I didn't have a mailer daemon running for it to send
failure notices through, I never knew it was bad until it was totally
borked. Once put into a cooler environment, I've never had another
problem with it.
