Uhmmm, can you elaborate on that?

O.K. I will try to:
# gmirror list
# mount
# swapinfo 
all show the about the same stuff as yours. During Raid setup I

inserted a line
swapoff=YES
into /etc/rc.conf -since it was recommended. It is still there 
can I remove it now or will there be any problems?


Thanks for your hints,

Uli.

I think they might have fixed that in 5.4, but it doesn't huirt to
have it there.  I've been careful to run shutdown command instead of
halt ...

If you get the same output as I do, I'd say you're alright.

Here's what my system looks like:

2) In case one of my disks fails (let's say ad2), what is the
   correct procedure to exchange it? My guess:
   - power down my machine


If you have hot-swap drive bays, you can skip this step.


   - insert new disk
   - # gmirror configure -a gm0
   - # gmirror insert gm0 /dev/ad2
   - wait until
 # gmirror list
 shows both disks active again 


You should only need the insert command, and you can certainly use the 
system while the disks are syncing, you'll just have impaired performance.


Cheers,
