apologies for the wasted bandwidth and time, there were unrelated other 
problems with the box
that i was not aware of. it works now.

[OpenAFS] vos dump - pipe reliability

[vladimir konrad]

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 strange 
crash which happened during
"vos dump" command. i made a change to the dump command to go to a pipe instead 
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 ( represents a real volume name):

vos dump   -localauth | gzip -c | split -b 1024m - 
$DUMP_DIRECTORY/.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 server 
the original volume exists on?
