    Command:

    volserver

    
    
    

    SYNOPSIS

           volserver
               [-log] [-p <number of processes>]
               [-auditlog <log path>] [-audit-interface (file | sysvmq)]
               [-udpsize <size of socket buffer in bytes>]
               [-d <debug level>]
               [-nojumbo] [-jumbo]
               [-enable_peer_stats] [-enable_process_stats]
               [-allow-dotted-principals] [-help]
    
    
    

    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.
    
               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.
    
           -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.
