    Command:

    buserver

    
    
    

    SYNOPSIS

           buserver [-database <database directory>]
               [-auditlog <log path>] [-audit-interface (file | sysvmq)]
               [-cellservdb <cell configuration directory>] [-resetdb]
               [-noauth] [-smallht] [-servers <list of ubik database servers>+]
               [-enable_peer_stats]  [-enable_process_stats] [-rxbind]
               [-p <number of threads>] [-help]
    
    
    

    DESCRIPTION

           The buserver command initializes the Backup Server, which runs on
           database server machines and maintains the Backup Database. In the
           conventional configuration, the binary file is located in the
           /usr/lib/openafs directory on a file server machine.
    
           The buserver command is not normally issued at the command shell
           prompt, but rather placed into a database 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
           file server machine as the local superuser "root".
    
           As it initializes, the Backup Server process creates the two files that
           constitute the Backup Database, bdb.DB0 and bdb.DBSYS1, in the
           /var/lib/openafs/db directory if they do not already exist. The Backup
           Database houses information about volume sets and entries, the dump
           hierarchy, Tape Coordinators, and previously performed dump sets. Use
           the commands in the backup suite to administer the database.
    
           The Backup Server records a trace of its activity in the
           /var/log/openafs/BackupLog file. Use the bos getlog command to display
           the contents of the file.
    
           This command does not use the syntax conventions of the AFS command
           suites. Provide the command name and all option names in full.
    
    
    

    CAUTIONS

           The buserver process reserves port 7021 for its use. Unexpected
           behavior can occur if another process tries to reserve this port while
           the buserver process is running.
    
    
    

    OPTIONS

           -database <database directory>
               Specifies the pathname of an alternate directory for the Backup
               Database files, ending in a final slash ("/"). If this argument is
               not provided, the default is the /var/lib/openafs/db directory.
    
           -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.
    
           -resetdb
               Removes all of the information in the Backup Database files in the
               /var/lib/openafs/db directory, leaving zero-length versions of
               them.  The backup operator must recreate the configuration entries
               in the database (for volume sets, the dump hierarchy and so on)
               before performing backup operations.
    
           -noauth
               Establishes an unauthenticated connection between the issuer and
               the Backup Server, in which the Backup Server treats the issuer as
               the unprivileged user "anonymous". It is useful only when
               authorization checking is disabled on the database server machine.
               In normal circumstances, the Backup Server allows only authorized
               (privileged) users to issue commands that affect or contact the
               Backup Database, and refuses to perform such an action even if the
               -noauth flag is used.
    
           -smallht
               Directs the Backup Server to use smaller internal hash tables for
               the Backup Database, which reduces memory requirements but can make
               data access take longer.
    
           -servers <list of ubik database servers>+
               Specifies the database server machines on which to start the Backup
               Server. Use this argument if running the Backup Server on a subset
               of the database server machines that is not a majority of the
               machines listed in the /etc/openafs/server/CellServDB file.
    
           -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.
    
           -rxbind
               Bind the Rx socket to the primary interface only.  (If not
               specified, the Rx socket will listen on all interfaces.)
    
           -p <number of threads>
               Sets the number of server lightweight processes (LWPs or pthreads)
               to run.  Provide a positive integer from the range 3 to 16. The
               default value is 3.
    
           -help
           conventional instead to create and start the process by issuing the bos
           create command.
