voldump - Dump an AFS volume without using the Volume Server
voldump -part <partition>
-volumeid <volume id>
[-file <dump file>] [-time

-vo <volume id>
[-f <dump file>] [-time <dump

[-ve] [-h]
voldump dumps an AFS volume in the format used by vos dump without using the Volume Server. It must be run on the file server machine and usually must be run as the superuser "root" to have permissions to read the file server data. It's primary use is to recover data from a file server machine where the Volume Server cannot be started for some reason.
The dump output will go to standard output, or to a file if -file is specified. vos restore can be used to load the resulting dump into a new AFS volume. voldump always does a full dump.
Normally, use vos dump instead of this command. voldump is a tool of last resort to try to extract data from the raw data structures stored on the file server machine and is not as regularly tested or used as the normal vos dump implementation.
If the AFS volume being dumped changes while voldump is running, the results may be inconsistent. If the File Server and Volume Server are running, stop them with bos shutdown or a similar method before running this command.
The following command dumps the volume 1936964939 on the /vicepb partition to the file /tmp/volume.dump:
% voldump -part /vicepb -volumeid 1936964939 -file /tmp/volume.dump
The issuer must have read access to the file server data stored in the specified partition. Usually, this means that the issuer must be the local superuser "root" on the file server machine.
