Hi,

This is on FreeBSD 5.4 latest stable snapshot on January.

I've followed the instructions at:
http://www.onlamp.com/pub/a/bsd/2005/11/10/FreeBSD_Basics.html  for =
creating software RAID, which appears to have been successful. the raid =
created, and synched, couple of reboots all is good.

So I wanted to test it out, I've unplugged one of the drives and =
rebooted, however, I've received the error:

ffs_mountroot: can't find rootvp
Root mount failed: 6
mountroot>

It doesn't matter which disk I unplug, it gives the same result. I've =
attempted to remount:

ufs:/dev/mirror/gm0s1a
ufs:/dev/ad6s1a
ufs:/dev/ad4s1a

no luck. so I looked over:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/geom-mirror.htm=
l

and added the 'options GEOM_MIRROR' to Kernel, then recompiled, =
installed and restarted, the machine would hang completely just when =
loading the AD drives.

Are the articles missing any steps ? any help is appreciated.

Thx,

Tamouh Hakmi
