It was fairly simple. The best suggestion for me was:
CTRL C out of the rmvol and then rmvol -v
This will show the files it is probably looping on.
You should probably delete these files and restore them if possible,
I did that and saw what was looping, moved those, and removed the volume.
However, now the domain has panicked -- I'll send out a separate email on that.
Other good advice was:
Are you sure you gave it enough time? rmvol takes a long time moving
data around. It does this transparent to users on the system. (I once
removed a volume from a running/active oracle database without
incident.) This process can take a quite a while. I know that 17GB disk
took over and hour, but the database was running, and fairly active.
Try using lsof to see if anything has a file open. I know in our case we
can't remove the volume where our Oracle executables reside until Oracle
has been stopped.
Thanks to Jeff Hummel, Paul Thompson, and Jim Fitzmaurice.

ORIGINAL QUESTION:
==================
Hi,
I'm trying to remove a volume from an AdvFS domain and having problems.
Here is the domain:
root_at_thor==> showfdmn -k home_domain
Id Date Created LogPgs Version Domain Name
3d0e2d5a.0007c3dd Mon Jun 17 14:41:30 2002 512 4 home_domain

---------- ---------- ------
29098320 26671768 8%
I want to remove /dev/disk/dsk15b. When I issue
rmvol /dev/disk/dsk15b home_domain
it just hangs. top shows rmvol getting about 10% of the cpu for a couple of minutes then it jumps up to 99% of the cpu until I interrupt it with ctrl-c (there is nothing else currently running on this box). I've tried balancing and defragmenting the domain as well as rebooting the box all to no avail.
We're running 5.1A PK2 (I think it's PK2) on a 4100.
Searching the archives has only turned up methods for removing this volume from the domain manually by removing the appropriate links in /etc/fdmns. However, I'm reluctant to do that because there may still be unmoved data stored there -- looks like about 16 mb.
Thank you!
