Fixing vinum after removing a HDD

[dontspamhenk at xs4all.nl]

Dear all,

I'm running FreeBSD 4.8 on a system with 5 HDD's. ad0 is to be removed
from the system. ad1, ad2 and ad3 contain my vinum drives. FreeBSD resides
on the last disk (da0).

Can anyone tell me if the following procedure is the right way to do it?
1. physically remove ad0
2. vinum resetconfig
3. change drivenumbers in vinum.conf
4. run vinum with the new configfile

Thanks, Marc


Disks currently in the system:
 ad0 (unused disk, to be removed from the system)
 ad1 <Maxtor 6Y080L0>	(contains 1st vinum subdisk)
 ad2 <Maxtor 6Y080L0>	(contains 2nd vinum subdisk)
 ad3 <Maxtor 6Y080L0>	(contains 3rd vinum subdisk)
 da0 <QUANTUM ATLAS10K2-TY092L DDD6>	(contains all system partitions)

My current vinum.conf:
 drive a device /dev/ad1s1h
 drive b device /dev/ad2s1h
 drive c device /dev/ad3s1h
 volume BigDisk0
 plex org concat
 sd length 78159m drive a
 sd length 78159m drive b
 sd length 78159m drive c


Disks after removing the 1st disk
 ad0 <Maxtor 6Y080L0>	(contains 1st vinum subdisk)
 ad1 <Maxtor 6Y080L0>	(contains 2nd vinum subdisk)
 ad2 <Maxtor 6Y080L0>	(contains 3rd vinum subdisk)
 da0 <QUANTUM ATLAS10K2-TY092L DDD6>    (contains all system partitions)

My future vinum.conf
 drive a device /dev/ad0s1h
 drive b device /dev/ad1s1h
 drive c device /dev/ad2s1h
 volume BigDisk0
 plex org concat
 sd length 78159m drive a
 sd length 78159m drive b
