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] [-help] vos lo -i <volume name or ID> [-c <cell name>] [-n] [-l] [-v] [-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. - -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".
