vos_unlock - Unlocks a single VLDB entry


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]


The vos unlock command releases the lock on the Volume Location Database (VLDB) entry for the indicated volume.


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.


-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).


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 /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).


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.


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


The following example unlocks the VLDB entry for the volume user.terry.

   % vos unlock user.terry


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.
