is there any reason that the dump to a pipe would be less reliable then the=
 dump to a file?

we have openafs 1.2.11 running on debian woody and i am investigating a str=
ange crash which happened during
"vos dump" command. i made a change to the dump command to go to a pipe ins=
tead of a file (i.e. no -file option),
it dumped most of the volumes with no problem and then crashed the OS.

the command run is effectively (<volume-name> represents a real volume name=
):

vos dump <volume-name>  -localauth | gzip -c | split -b 1024m - $DUMP_DIREC=
TORY/<volume-name>.dump.

there is enough space for the dumps in $DUMP_DIRECTORY.

also, does a volume read-only snapshot have to be created on the same serve=
r the original volume exists on?
