voldump - Dump an AFS volume without using the Volume Server
voldump -part <partition> -volumeid <volume id>
[-file <dump file>] [-verbose] [-help]
voldump -p <partition> -vo <volume id>
[-f <dump file>] [-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. Its 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
Names the partition on which the volume to be dumped is located.
voldump does not take the normal full range of ways of specifying a
partition. Instead, partition must be either a single letter between
a and z, corresponding to /vicepa through /vicepz, or the full
path to the file server partition. aa is not recognized; use
-volumeid <volume id>
Specifies the ID of the volume to dump. The volume must be specified by
numeric ID, not by name.
-file <dump file>
Specifies the output file for the dump. If this option is not given, the
volume will be dumped to standard output.
Asks for a verbose trace of the dump process. This trace information will
be sent to standard error.
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.
