vos_syncserv - Verifies VLDB entries that mention a specified site


vos syncserv -server <machine name>
[-partition <partition name>]
[-cell <cell name>]
[-noauth] [-localauth]
[-verbose] [-encrypt] [-noresolve]
[-config <config directory>]

vos syncs -s <machine name>
[-p <partition name>]
[-c <cell name>] [-d]
[-noa] [-l] [-v] [-e] [-nor]
[-co <config directory>]


The vos syncserv command verifies that each volume mentioned in a VLDB entry actually exists at the site indicated in the entry. It checks all VLDB entries that mention a read/write, read-only, or backup site either on any partition on the file server machine specified by the -server argument, or on the one partition specified by the -server and -partition arguments. Note that the command can end up inspecting sites other than those specified by the -server and -partition arguments, if there are versions of the volume at sites other than the one specified.

The command alters any incorrect information in the VLDB, unless there is an irreconcilable conflict with other VLDB entries. In that case, it writes a message to the standard error stream instead. The command never removes volumes from file server machines.

To achieve complete VLDB consistency, first run the vos syncvldb command on all file server machines in the cell, then run this command on all file server machines in the cell.


Identifies the file server machine mentioned in each VLDB entry to check. Provide the machine's IP address or its host name (either fully qualified or using an unambiguous abbreviation). For details, see vos(1).
Identifies the partition mentioned in each VLDB entry to check. Provide the partition's complete name with preceding slash (for example, "/vicepa") or use one of the three acceptable abbreviated forms. For details, see vos(1).
Show the actions which would be taken, but do not make changes.
Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see vos(1).
Assigns the unprivileged identity "anonymous" to the issuer. Do not combine this flag with the -localauth flag. For more details, see vos(1).
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The vos command interpreter presents it to the Volume Server and Volume Location Server during mutual authentication. Do not combine this flag with the -cell argument or -noauth flag. For more details, see vos(1).
Produces on the standard output stream a detailed trace of the command's execution. If this argument is omitted, only warnings and error messages appear.
Encrypts the command so that the operation's results are not transmitted across the network in clear text. This option is available in OpenAFS versions 1.4.11 or later and 1.5.60 or later.
Shows all servers as IP addresses instead of the DNS name. This is very useful when the server address is registered as or when dealing with multi-homed servers. This option is available in OpenAFS versions 1.4.8 or later and 1.5.35 or later.
Set the location of the configuration directory to be used. This defaults to /etc/openafs, except if -localauth is specified, in which case the default is /etc/openafs/server. This option allows the use of alternative configuration locations for testing purposes.
Prints the online help for this command. All other valid options are ignored.


The following example verifies the VLDB entries in which a site definition mentions the file server machine "".

   % vos syncserv -server


The issuer must be listed in the /etc/openafs/server/UserList file on the machine specified with the -server argument and on each database server machine. If the -localauth flag is included, the issuer must instead be logged on to a server machine as the local superuser "root".
