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. With‐
out this flag, this command cannot remove volumes that are not attach‐
able. 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 com‐
mand, 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 com‐
mand 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 Vol‐
ume Server examines all inodes on the partition for traces of the vol‐
ume.
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 identi‐
fies 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/ope‐
nafs/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 com‐
mand’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
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".
