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".
