I'm having problems doing a dump.bsd to a SyQuest removeable
cartridge.  I've formatted the cartridges, and set them up with a
slice 4 partition using SilverLining.  I have no problems dumping
the /usr and /users partitions, but when I try dumping / I get an
error:

$ dump.bsd 0fs /dev/dsk/c2d0s4 42m /
DUMP: Date of this level 0 dump: Mon Dec  3 01:32:45 1990
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping / to /dev/dsk/c2d0s4
DUMP: bad sblock magic number
DUMP: The ENTIRE dump is aborted.

Running fsstat gives the following error:

$ fsstat /
/: bad filesystem state, run fsck

So of course I ran fsck, it came up clean, no problems. But if I try
dumping again, I get the same problem.  Can anyone help me to solve
this one??

Since then I've tried fsstat on my other filesystems and they are
all reported as bad!!  However they both dump correctly.

Try using /dev/rdsk/c0d0s0 (or the equivalent, if your root is somewhere
else) instead of the name / .  I have had the same problem here, and it
only shows up when trying to dump root.
