       The volserver command initializes the Volume Server component of the "fs" process. In the
       conventional configuration, its binary file is located in the /usr/lib/openafs directory
       on a file server machine.

       The volserver command is not normally issued at the command shell prompt but rather placed
       into a file server machine's /etc/openafs/BosConfig file with the bos create command. If
       it is ever issued at the command shell prompt, the issuer must be logged onto a database
       server machine as the local superuser "root".

       The Volume Server records a trace of its activity in the /var/log/openafs/VolserLog file.
       Use the bos getlog command to display the contents of the file.

       The Volume Server processes the vos commands that administrators use to create, delete,
       move, and replicate volumes, as well as prepare them for archiving to tape or other media.

       By default, the VL Server runs nine lightweight processes (LWPs). To change the number,
       use the -p argument.

       This command does not use the syntax conventions of the AFS command suites. Provide the
       command name and all option names in full.


       -d <debug level>
           Sets the detail level for the debugging trace written to the
           /var/log/openafs/VolserLog file. Provide one of the following values, each of which
           produces an increasingly detailed trace: 0, 1, 5, 25, and 125.

           Records in the /var/log/openafs/VolserLog file the names of all users who successfully
           initiate a vos command. The Volume Server also records any file removals that result
           from issuing the vos release command with the -f flag.

           Use Transarc style logging features. Rename the log file /var/log/openafs/VolserLog to
           /var/log/openafs/VolserLog.old when the volume server is restarted.  This option is
           provided for compatibility with older versions.

       -p <number of processes>
           Sets the number of server lightweight processes (LWPs) to run.  Provide an integer
           between 4 and 16. The default is 9.

       -auditlog <log path>
           Turns on audit logging, and sets the path for the audit log.  The audit log records
           information about RPC calls, including the name of the RPC call, the host that
           submitted the call, the authenticated entity (user) that issued the call, the
           parameters for the call, and if the call succeeded or failed.

       -audit-interface (file | sysvmq)
           Specifies what audit interface to use. Defaults to "file". See fileserver(8) for an
           explanation of each interface.

       -udpsize <size of socket buffer>
           Sets the size of the UDP buffer in bytes, which is 64 KB by default. Provide a
           positive integer, preferably larger than the default.

           Allows the server to send and receive jumbograms. A jumbogram is a large-size packet
           composed of 2 to 4 normal Rx data packets that share the same header. The volserver
           does not use jumbograms by default, as some routers are not capable of properly
           breaking the jumbogram into smaller packets and reassembling them.

           Deprecated; jumbograms are disabled by default.

           Activates the collection of Rx statistics and allocates memory for their storage. For
           each connection with a specific UDP port on another machine, a separate record is kept
           for each type of RPC (FetchFile, GetStatus, and so on) sent or received. To display or
           otherwise access the records, use the Rx Monitoring API.

           Activates the collection of Rx statistics and allocates memory for their storage. A
           separate record is kept for each type of RPC (FetchFile, GetStatus, and so on) sent or
           received, aggregated over all connections to other machines. To display or otherwise
           access the records, use the Rx Monitoring API.

           By default, the RXKAD security layer will disallow access by Kerberos principals with
           a dot in the first component of their name. This is to avoid the confusion where
           principals user/admin and user.admin are both mapped to the user.admin PTS entry.
           Sites whose Kerberos realms don't have these collisions between principal names may
           disable this check by starting the server with this option.

           Clear volume access statistics during volume restore and reclone operations.  This
           includes clearing the volume access statistics of read-only volumes during a volume
           release.  By default, volume access statistics are preserved during volume restore and
           reclone operations.

           Volume access statistics were cleared by default in versions prior to OpenAFS 1.8.0.
           This flag is intended to provide compatible behaviour.

       -sync <sync behavior>
           This is the same as the -sync option in fileserver(8). See fileserver(8).

       -logfile <log file>
           Sets the file to use for server logging.  If logfile is not specified and no other
           logging options are supplied, this will be /var/log/openafs/VolserLog.  Note that this
           option is intended for debugging and testing purposes.  Changing the location of the
           log file from the command line may result in undesirable interactions with tools such
           as bos.

       -config <configuration directory>
           Set the location of the configuration directory used to configure this service.  In a
           typical configuration this will be /etc/openafs/server - this option allows the use of
           alternative configuration locations for testing purposes.

       -rxmaxmtu <bytes>
           Defines the maximum size of an MTU.  The value must be between the minimum and maximum
           packet data sizes for Rx.

           Bind the Rx socket to the primary interface only. (If not specified, the Rx socket
           will listen on all interfaces.)

       -syslog[=<syslog facility>]
           Specifies that logging output should go to syslog instead of the normal log file.
           -syslog=FACILITY can be used to specify to which facility the log message should be

       -sleep <sleep_time/run_time>
           This option is obsolete, and is now only accepted for compatibility with older
           releases. All it does now is log a warning message about how the option is obsolete.

       -restricted_query (anyuser | admin)
           Restrict RPCs that query information about volumes to a specific group of users. You
           can use "admin" to restrict to AFS administrators.  The "anyuser" option doesn't
           restrict the RPCs and leaves it open for all users including unauthenticated users,
           this is the default.

       -s2scrypt (never | always | inherit)
           Set the cryptographic disposition of inter-volserver traffic.

               All inter-volserver traffic is unencrypted.  This is the default behavior.

               All inter-volserver traffic is encrypted (using rxkad).

               Inter-volserver traffic will be encrypted if the client connection triggering the
               server-to-server traffic is encrypted.  This has the effect of encrypting inter-
               server traffic if the "-encrypt" option is provided to vos release, for example.

           Prints the online help for this command. All other valid options are ignored.


       The following bos create command creates a "volserver" process on the machine
       "" as part of the fs process:

          % bos create -server -instance fs -type fs \
                       -cmd "/usr/lib/openafs/fileserver" \
                       /usr/lib/openafs/volserver /usr/lib/openafs/salvager


       The issuer must be logged in as the superuser "root" on a file server machine to issue the
       command at a command shell prompt. It is conventional instead to create and start the
       process by issuing the bos create command.
