vldb_check - Checks the integrity of the VLDB
] [ -vheader
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.
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.
- -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.
- Displays information which Ubik maintains in the database's
- Displays information which the VL Server maintains in the
- -servers <authentication servers>+
- Outputs the server entries from the VLDB, which list the IP
addresses registered for each file server machine in the cell.
- Outputs every volume entry in the database. The information
includes the volume's name and the volume ID number for each of its
- Blocks output from going to stdout. Output to stderr is not
blocked. Cannot be used with -verbose, -uheader, -servers or
- Reports additional information about the database,
including the number of entries for each type of volume. Cannot be used
- Prints the online help for this command. All other valid
options are ignored.
If there are errors in the database, the output always reports them on the
standard error stream. If any options other than -database
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.
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.
The issuer must be logged in as the local superuser "root".
