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".
