advfs and defective volume

Hi!

on one of our machines (DEC OSF 4.0D) /usr is an advfs fileset
spanning multiple (3) disks. one of these (a RZ28M) went south
yesterday (unrecoverable read errors).

I got another RZ28M, "addvol"ed it to usr_domain and tried to
"rmvol" the flaky one.

Unfortunately, rmvol stopped as soon as it hit a read error..
so i first ran "balance" to "fill up the new disk" and then
ran "rmvol" in a loop, manually removing the "bad file" that
stopped each pass.

That is, until rmvol got stuck on <unknown> entries..
 

To make matters worse, the drive is deteriorating rapidly, which means
that (most) attempts to mount /usr crash after multiple read errors ..

Question:
- how would advfs cope with a *missing* volume (as in "physically
removed")
- could the remaining data (on the other disks) be salvaged?
    
TiA,
Steffen
