DESCRIPTION

       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.

OPTIONS

       -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.

       -log
           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.

       -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.

       -jumbo
           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.

       -nojumbo
           Deprecated; jumbograms are disabled by default.

       -enable_peer_stats
           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.

       -enable_process_stats
           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.

       -allow-dotted-principals
           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.

       -preserve-vol-stats
           Preserve volume access statistics over volume restore and reclone operations.  By
           default, volume access statistics are reset during volume restore and reclone
           operations.

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

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

EXAMPLES

       The following bos create command creates a "volserver" process on the machine
       "fs2.abc.com" as part of the fs process:

          % bos create -server fs2.abc.com -instance fs -type fs \
                       -cmd "/usr/lib/openafs/fileserver" \
                       /usr/lib/openafs/volserver /usr/lib/openafs/salvager

PRIVILEGE REQUIRED

       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.
