VOS_SYNCVLDB(1) AFS Command Reference VOS_SYNCVLDB(1)NAMEvos_syncvldb - Verifies VLDB entries for volumes residing at specified
site
SYNOPSIS
vos syncvldb [-server <machine name>]
[-partition <partition name>]
[-volume <volume name or ID>]
[-dryrun] [-cell <cell name>]
[-noauth] [-localauth]
[-verbose] [-encrypt] [-noresolve] [-help]
vos syncv [-s <machine name>]
[-p <partition name>]
[-vo <volume name or ID>]
[-d] [-c <cell name>]
[-noa] [-l] [-ve] [-e] [-nor] [-h]
DESCRIPTION
The vos syncvldb command verifies that the status of the volumes housed
either on all partitions on the file server machine specified by the
-server argument, or on the single partition specified by the -server
and -partition arguments, is recorded correctly in the VLDB. If the
-volume argument is included to indicate a single volume, the command
compares only its status on the file server machine with its VLDB
entry.
If the -volume argument is not included, the command interpreter
obtains from the Volume Server a list of the volumes that reside on
each partition, then changes information in the VLDB as necessary to
reflect their state on the partition. For example, it creates or
updates a VLDB entry when it finds a volume for which the VLDB entry is
missing or incomplete. However, if there is already a VLDB entry that
defines a different location for the volume, or there are
irreconcilable conflicts with other VLDB entries, it instead writes a
message about the conflict to the standard error stream. The command
never removes volumes from the file server machine.
To achieve complete VLDB consistency, run this command on all file
server machines in the cell, and then run the vos syncserv command on
all file server machines in the cell.
Using the -volume argument basically combines the effects of this
command with those of the vos syncserv command, for a single volume.
The command not only verifies that the VLDB entry is correct for the
specified volume type (read/write, backup, or read-only), but also
checks that any related volume types mentioned in the VLDB entry
actually exist at the site listed in the entry. It is not necessary to
provide the -server argument (and optionally, -partition argument); if
one or both is provided, the results are reliable only if they specify
the actual location of the volume indicated by the -volume argument.
OPTIONS-server <server name>
Identifies the file server machine housing the volumes for which to
verify VLDB entries. Provide the machine's IP address or its host
name (either fully qualified or using an unambiguous abbreviation).
For details, see vos(1).
-partition <partition name>
Identifies the partition housing the volumes for which to verify
VLDB entries. Provide the -server argument along with this one.
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).
-volume <volume name or ID>
Specifies the name or volume ID number of a single volume for which
to verify the VLDB entry. This argument can be combined with the
-server (and optionally, the -partition) argument.
-cell <cell name>
Names the cell in which to run the command. Do not combine this
argument with the -localauth flag. For more details, see vos(1).
-dryrun
Show the actions which would be taken, but do not make changes.
-noauth
Assigns the unprivileged identity "anonymous" to the issuer. Do not
combine this flag with the -localauth flag. For more details, see
vos(1).
-localauth
Constructs a server ticket using a key from the local
/usr/afs/etc/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).
-verbose
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.
-encrypt
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.
-noresolve
Shows all servers as IP addresses instead of the DNS name. This is
very useful when the server address is registered as 127.0.0.1 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.
-help
Prints the online help for this command. All other valid options
are ignored.
EXAMPLES
The following example command verifies the VLDB entry for each volume
stored on the file server machine "fs4.abc.com".
% vos syncvldb fs4.abc.com
PRIVILEGE REQUIRED
The issuer must be listed in the /usr/afs/etc/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".
