       davolserver - Initializes the Volume Server component of the dafs

           [-auditlog <log path>] [-audit-interface (file | sysvmq)]

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

       The davolserver 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.

       -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

           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

           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

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


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

          % bos create -server -instance dafs -type dafs \
                       -cmd "/usr/lib/openafs/dafileserver" \
                       /usr/lib/openafs/davolserver \
                       /usr/lib/openafs/salvageserver \


       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.
