It took a while to solve this ... my thanks to everyone who
originally responded. The ideas were very helpful.
Original problem: Try to ufsdump a 20+gig disk to an 8mm, 160m
tape. The ufsdump would error out at what appeared to be the end of the
first tape, despite using the "l" option in the ufsdump command.
Solution: When the 20+gig partition was split in to two 10-gig
partitions, the ufsdump worked! We were also able to ufsdump a 13-gig
partition to multiple 8 mm tapes without using compression.
My guess, which I have presented to Sun Support, is that we have hit
some kind of hard-coded limit with ufsdump with 20+gig partitions. Perhaps
the fact that the 20+gig partition is larger than the capacity of a single
8mm tape (14+ gig using compression) has something to do with it, even
though the "l" option is used.
Would anyone out there have any ideas or opinions on why a partition
that large wouldn't work?
Is anyone out there using a Seagate Barracuda disk (18 gig) as a
single partition and using ufsdump? After formatting the Barracuda, how
large is the partition?
