ufsdump/ufsrestore of large filesystem

Hello:
        SunBlade 1000, two internal drives, system on 18G, trying to
migrate slices (and resize) to 36G drive. I have a large root
filesystem, roughly 5.5G. I've set up the slices on the drive and
migrated the smaller filesystem without problem using:

ufsdump 0f - /dev/rdsk/c#t#d#s# | (cd /1/<matched
filesystem>;ufsrestore xf -), where the new slice is mounted under the
appropriate /1 (/ is under /1, /var is under /1/var, etc.).

Trying to do it on the large filesystem I get
.
.
.
.

DUMP: 96.79% done, finished in 0:01
changing volumes on pipe input
abort? [yn] y
dump core? [yn] n
  DUMP: 10579134 blocks (5165.59MB) on 1 volume at 1130 KB/sec
  DUMP: DUMP IS DONE

When I try to do it in two steps, ufsdump-ing it to a file using
ufsdump -0f <dumpfilename> /dev/rdsk/c#t#d#s#  this
part works fine
and then restoring it
cd /1
ufsrestore xf <dumpfilename>

the restore runs for a little while and then I get the following:

You have not read any volumes yet.
Unless you know which volume your file(s) are on you should start
with the last volume and work towards the first.
Specify next volume #:

Any help would be greatly appreciated.

Thanks
-Dave
