ufsdump errors

This is on a:

SunOS goshawk-anh 5.7 Generic_106541-08 sun4u sparc SUNW,Ultra-80

system.

Every night when ufsdump runs I'm getting output like:

 DUMP: Writing 32 Kilobyte records
 DUMP: Date of this level 0 dump: Wed Oct 15 00:50:37 2003
 DUMP: Date of last level 0 dump: the epoch
 DUMP: Dumping /dev/md/rdsk/d2 (goshawk-anh:/oracle) to standard output.

 DUMP: Warning - block 269355016 is beyond the end of `/dev/md/rdsk/d2'

/dev/md/dsk/d2 has a grand total of 24,401,826 blocks, so not only are
those blocks beyond the end of the filesystem, they are right off the
end and into the next rack! :)

I've checked sunsolve, and googled, and the only answers I can find are:

    1. fsck the disk
    2. check for patches

well I've done both - fdisk makes no difference, and there aren't any
patches that I can find for 2.7 that are relevant. The metadevice is
healthy:

d2: Concat/Stripe
    Size: 142245693 blocks
    Stripe 0: (interlace: 32 blocks)
        Device Start Block Dbase
        c1t1d0s0 0 No
        c1t9d0s0 2889 No

I am very puzzled. All suggestions gratefully received. I'll summarize.

Cheers,

Doug.
