Yes you have understood correctly.
Most of the RAID systems I have setup are mirror on 2 IDE disks.
In the few cases a disk has failed, I:
- turn the machine off (in many cases the system has frozen anyway)
- remove the old disk and put a new one in
kernel messages show which disk is being used and the missing one should =

When you say `replace' I am not sure whether you mean, `physically
replace', or `raidctl -F'.
The system can only accommodate two physical disks. So I have to
remove the dead disk first, and I'd rather the system were powered off
when I did that. :-)
So I guess another way to put my question is: if I power off,
physically replace the failed disk, and restart, how will Raidframe
react to this?
I *think* what you are saying is that, whereas now I have:
after restarting the machine I will have:
and, therefore, I will be able to introduce (the new) wd0d into the
RAID without any complications.
Have I understood you correctly?
