Rescuing a AdvFS domain with one crashed disk.

Hi list,

If I've missed an earlier discussion on this topic in the archives, please
excuse me and please give me a pointer.

And, don't give me any comments on the subject of backups, I've already
gotten them from my collegues and given them to myself so.....

What I have/did have is/was a DU v4.0b system with a AdvFS domain
consisting of 3 volumes. Since this is sort of a public scratch area, so
backups are kept to a minimum.

Now, one of the volumes in this domain crashed. Trying to access it or the
domain just gives you a lot of CAM errors etc. Since this crashed volume was
the last one added to the domain and haven't done any manual balancing, I'm
hoping that the amount of data stored on that specific disk in relation to the
total amount is relatively small.

In my attempts to rescue what can be rescued, I've tried to unlink the
pointer in /etc/fdmns and used mount/verify/rmvol/etc. in different
combinations but to no avail. All it ever says is that it expects three disks
but that there are only pointer to two or gives you CAM errors.

So, my question is, is there a way to rescue the information on the two
remaining disks ?

TIA,
//Fredrik
