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] [-encrypt] [-noresolve]
           [-config <config directory>]
           [-help]

       vos z -s <machine name>
           -p <partition name>
           -i <volume ID>
           [-f] [-b] [-c <cell name>]
           [-noa] [-l] [-v] [-e] [-nor]
           [-co <config directory>]
           [-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 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.

       -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.

       -config <configuration directory>
           Set the location of the configuration directory to be used. This defaults to /etc/openafs, except if
           -localauth is specified, in which case the default is /etc/openafs/server. This option allows the use
           of alternative configuration locations for testing purposes.

       -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.example.com", without noting the change in the VLDB.

          % vos zap -server fs6.example.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".
