For their help with this issue. 

Suggested Resolutions included:

* Don't use Slice 2 (s2) for Disksuite slices. Instead use 0 or 6.
* Don't combine metadb and dataslices
* fsck the volume
* Ensure that all drives have the same partition table with:
  prtvtoc /dev/rdsk/c3t0d0s2 | fmthard -s - /dev/rdsk/c3t1d0s2
* Check the A1000 Configuration and Patch Matrix, make sure patches
  are up to date.
* Check /etc/system, make sure all appropriate MD entries are in there.

Patch Matrix information Located here:

The interesting thing here is that none of these suggestions fixed our
issue. Our newfs was working, but the volume was unmountable. Mount 
attempts continually gave a 'not of this fstype' error, and while I did 
have the metadb and data on the same slices, that's supported by 
Disksuite. We were using slice2, though, but I don't think it's as much of 
an issue as people made it out to be; metadb checks passed, as well as all 
other checks, even with everthing on slice 2. 

Resolution
----------

What eventually fixed this was to reconstruct the entire RAID5, moving our
data slices onto slice 6, metadb onto slice zero, and doing a new 
newfs on the filesystem as:

	newfs -v -c 16 -C 7 -m 0 -o space /dev/md/rdsk/d10

I found this command on sunmanagers:
http://www.netsys.com/sunmgr/2001-01/msg00411.html

...in a reference to building filesystems on sun4u.

Our machine's 'uname -a' output is: 
SunOS db3 5.8 Generic sun4u sparc SUNW,Ultra-80

And the volume size is:
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/md/dsk/d10      173752554       9 173752545     1%    /raid3

Thanks again,
