VOS_LOCK(1)						       AFS Command Reference						       VOS_LOCK(1)

NAME
       vos_lock - Locks a VLDB volume entry

SYNOPSIS
       vos lock -id <volume name or ID>
	   [-cell <cell name>]
	   [-noauth] [-localauth]
	   [-verbose] [-encrypt] [-noresolve] [-help]

       vos lo -i <volume name or ID>
	   [-c <cell name>]
	   [-noa] [-l] [-v] [-e] [-nor] [-h]

DESCRIPTION
       The vos lock command locks the Volume Location Database (VLDB) entry for the indicated volume, blocking any operation that requires a write
       to that entry. The lock applies to all of the volume versions associated with the entry, not just the one specified with the -id argument.

       To unlock a single VLDB entry, use the vos unlock command. To unlock several entries, or all locked entries in the VLDB, use the vos
       unlockvldb command.

CAUTIONS
       Do not use this command in normal circumstances. It is useful for guaranteeing that the volume stays unchanged when there is reason to
       believe that volume operations cannot properly lock VLDB volume entries as they normally do to synchronize with one another.

OPTIONS
       -id <volume name or ID>
	   Specifies either the complete name or volume ID number of a volume of the any of the three types.

       -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).

       -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 /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).

       -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 command locks the VLDB entry for "user.terry".

	  % vos lock user.terry

PRIVILEGE REQUIRED
       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".

VOS_UNLOCK(1)						       AFS Command Reference						     VOS_UNLOCK(1)

NAME
vos_unlock - Unlocks a single VLDB entry SYNOPSIS
vos unlock -id <volume name or ID> [-cell <cell name>] [-noauth] [-localauth] [-verbose] [-encrypt] [-noresolve] [-help] vos unlock -i <volume name or ID> [-c <cell name>] [-noa] [-l] [-v] [-e] [-nor] [-h] DESCRIPTION
The vos unlock command releases the lock on the Volume Location Database (VLDB) entry for the indicated volume. CAUTIONS
Do not user this command under normal circumstances. It is useful if the VLDB entry is locked but there is no reason to suspect inconsistency within the volume or between it and the VLDB. Note that it is possible to list information from locked VLDB entries, even though they cannot be manipulated in other ways. The vos unlockvldb command unlocks several VLDB entries at once, or even the entire VLDB. The vos lock command locks a VLDB entry so that no one else can perform an action that requires writing the VLDB. OPTIONS
-id <volume name or ID> Specifies either the complete name or volume ID number of a volume of any of the three types. -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). -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 /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.

The following example unlocks the VLDB entry for the volume "user.terry". % vos unlock user.terry PRIVILEGE REQUIRED
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". SEE ALSO
