gmirror problems

[Michael Riexinger]

Hi, 

I set up FreeBSD 5.3 with gmirror for my 2 ide disks ad0 and ad1. So the 
rootfs is included in the mirror. I wanted to test what happens when 
one disk fails, so I removed ad1. Unfortunately after a reboot the 
system didn't boot anymore with the error: 
GEOM_MIRROR: Force device mirror0 start due to timeout 
and
GEOM_MIRROR: Device mirror0 destroyed

So I mounted the rootfs from ad0: which worked fine. I attached the ad1 
again, rebooted and booting from the mirror went and gmirror rebuilded 
the raid. My next test was putting ad1 off and replacing it with a new 
hd, did that, rebooted and again:

GEOM_MIRROR: Force device mirror0 start due to timeout 
and
GEOM_MIRROR: Device mirror0 destroyed

Why is that? Shouldn't gmirror detect the new drive and rebuild the 
mirror?
Thanks!
