NAME

       vldb_check - Checks the integrity of the VLDB

SYNOPSIS

       vldb_check -database <vldb file> [-uheader] [-vheader]
           [-servers] [-entries] [-quiet | -verbose] [-help]

       vldb_check -d <vldb file> [-u] [-vh] [-s] [-e]
           [-ve] [-h]

DESCRIPTION

       The vldb_check command checks the integrity of the Volume Location Database (VLDB),
       reporting any errors or corruption it finds.  If there are problems, do not issue any vos
       commands until the database is repaired.

CAUTIONS

       The results can be unpredictable if the Volume Location (VL) Server makes changes to the
       VLDB while this command is running. Use the bos shutdown command to shutdown the local
       vlserver process before running this command, or before creating a second copy of the
       vldb.DB0 file (with a different name) on which to run the command.

OPTIONS

       -database <vldb file>
           Names the VLDB (copy of the vldb.DB0 file) to check. If the current working directory
           is not the location of the file, provide a pathname, either full or relative to the
           current working directory.

       -uheader
           Displays information which Ubik maintains in the database's header.

       -vheader
           Displays information which the VL Server maintains in the database's header.

       -servers <authentication servers>+
           Outputs the server entries from the VLDB, which list the IP addresses registered for
           each file server machine in the cell.

       -entries
           Outputs every volume entry in the database. The information includes the volume's name
           and the volume ID number for each of its versions.

       -quiet
           Blocks output from going to stdout. Output to stderr is not blocked. Cannot be used
           with -verbose, -uheader, -servers or -entries.

       -verbose
           Reports additional information about the database, including the number of entries for
           each type of volume. Cannot be used with -quiet.

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

OUTPUT

       If there are errors in the database, the output always reports them on the standard error
       stream. If any options other than -database or -help are provided, the output written to
       the standard output stream includes additional information as described for each option in
       OPTIONS.  The output is intended for debugging purposes and is meaningful to someone
       familiar with the internal structure of the VLDB.

       The -quiet option can be used to suppress the standard output stream so that the command
       can be used more easily inside scripts.

       The command exits with one of the following completion codes:

       0: No errors or warnings have been encountered.  1: One or more warnings encountered.  2:
       One or more warnings and/or errors encountered.  4: A fatal or internal error has occurred
       and the program cannot proceed.

PRIVILEGE REQUIRED

       The issuer must be logged in as the local superuser "root".
