NAME

       vos_zap - Removes a volume from its site without writing to the VLDB

SYNOPSIS

       vos zap -server <machine name> -partition <partition name>
           -id <volume ID> [-force] [-backup]
           [-cell <cell name>] [-noauth] [-localauth] [-verbose]
           [-help]

       vos z -s <machine name> -p <partition name>
           -i <volume ID> [-f] [-b] [-c <cell name>] [-n]
           [-l] [-v] [-h]

DESCRIPTION

       The vos zap command removes the volume with the specified volume ID
       from the site defined by the -server and -partition arguments, without
       attempting to change the corresponding Volume Location Database (VLDB)
       entry. If removing the volume can possibly result in incorrect data in
       the VLDB, a warning message is displayed.

       The -force flag removes a volume even if it cannot be "attached"
       (brought online), which can happen either because the volume is
       extremely damaged or because the Salvager functioned abnormally.
       Without this flag, this command cannot remove volumes that are not
       attachable. See also CAUTIONS.

       To remove the specified read/write volume’s backup version at the same
       time, include the -backup flag.

CAUTIONS

       Do not use this command as the standard way to remove a volume, as it
       is likely to put the VLDB out of sync with the volumes on servers. Use
       the vos remove command instead.

       This command is useful in situations where it is important to delete
       the volume, but for some reason the VLDB is unreachable -- for example,
       because s the Volume Location Server is unavailable. The issuer can
       remove the VLDB entry later with the vos remove or vos delentry
       command, or it is removed automatically when the vos syncserv and vos
       syncvldb commands run.

       To remove a read-only site defined in the VLDB by mistake, before a
       copy actually exists at the site, use the vos remsite command. To
       remove an entire VLDB entry without affecting volumes at their sites,
       use the vos delentry command.

       Do not use the -force flag if the volume is online, but only when
       attempts to remove the volume with the vos remove or the vos zap
       command have failed, or the volume definitely cannot be attached. After
       using the -force flag, make sure that the volume’s VLDB entry is also
       removed (issue the vos delentry command if necessary).

       Adding the -force flag makes the command take considerably longer --
       about as long as a salvage of the relevant partition -- since the
       Volume Server examines all inodes on the partition for traces of the
       volume.

OPTIONS

       -server <server name>
           Identifies the file server machine from which to remove the volume.
           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 (on the file server machine specified by
           the -server argument) from which to remove the volume. 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).

       -id <volume ID>
           Specifies the volume ID number of the volume to remove, which can
           be of any of the three types. The volume name is not acceptable.

       -force
           Removes the volume even though it cannot be attached (brought
           online). Use only after the failure of previous attempts to remove
           the volume by using the vos remove command or the vos zap command
           without this flag.

       -backup
           Removes the backup version of the read/write volume specified by
           the -id argument. Do not use this flag if the -id argument
           identifies a read-only or backup volume.

       -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 example removes the volume with volume ID 536870988 from
       the /vicepf partition of the file server machine "fs6.abc.com", without
       noting the change in the VLDB.

          % vos zap -server fs6.abc.com -partition f -id 536870988

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".
