vos_zap - Removes a volume from its site without writing to the VLDB
vos zap -server <machine name>
-partition <partition name>
-id <volume ID>
[-cell <cell name>]
[-verbose] [-encrypt] [-noresolve] [-help]
vos z -s <machine name>
-p <partition name>
-i <volume ID>
[-f] [-b] [-c <cell name>]
[-noa] [-l] [-v] [-e] [-nor] [-h]
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
To remove the specified read/write volumes backup version at the same
time, include the -backup flag.
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
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
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 volumes 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.
-server <server name>
Identifies the file server machine from which to remove the volume.
Provide the machines 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
partitions complete name with preceding slash (for example, /vicepa)
or use one of the three acceptable abbreviated forms. For details, see
-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.
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.
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).
Assigns the unprivileged identity anonymous to the issuer. Do not
combine this flag with the -localauth flag. For more details, see
Constructs a server ticket using a key from the local
/usr/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).
Produces on the standard output stream a detailed trace of the commands
execution. If this argument is omitted, only warnings and error messages
Encrypts the command so that the operations 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.
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.
Prints the online help for this command. All other valid options are
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
The issuer must be listed in the /usr/local/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.
