The vos remove command removes the indicated volume from
the partition on which it resides. The Volume Location Database (VLDB)
record is altered appropriately, as described in the following paragraphs.
Use this command to remove any of the three types of volumes; the effect
depends on the type.
- If the -id argument names the read/write volume (that is, specifies
the volume's base name), both it and the associated backup volume are
removed from the partition that houses them. The -server and
-partition arguments are optional, because there can be only one
read/write site. When the volume is removed, the site information is also
removed from the VLDB entry. The read/write and backup volume ID numbers
no longer appear in the output from the vos listvldb or vos
examine commands, but they are preserved internally. Read-only sites,
if any, are not affected, but cannot be changed unless a read/write site
is again defined. The site count reported by the vos examine and
vos listvldb commands as "number of
sites" decrements by one. The entire VLDB entry is removed if
there are no read-only sites.
- If the -id argument names a read-only volume, it is removed from
the partition that houses it, and the corresponding site information is
removed from the VLDB entry. The site count reported by the vos
examine and vos listvldb commands as
"number of sites" decrements by one for
each volume you remove. If there is more than one read-only site, the
-server argument (and optionally -partition argument) must
be used to specify the site from which to remove the volume. If there is
only one read-only site, the -id argument is sufficient; if there
is also no read/write volume in this case, the entire VLDB entry is
removed.
- If the -id argument names a backup volume, it is removed from the
partition that houses it. The -server and -partition
arguments are optional, because there can be only one backup site. The
backup volume ID number no longer appears in the output from the vos
listvldb command or in the corresponding portion of the output from
the vos examine command, but is preserved internally.
This command is the most appropriate one for removing volumes in
almost all cases. Other commands that remove only volumes or only VLDB
entries (such as the vos delentry, vos remsite and vos
zap commands) by definition can put the volumes and VLDB out of sync.
Use them only in the special circumstances mentioned on their reference
pages. Like the vos delentry command, this command can remove
a VLDB entry when no corresponding volumes exist on the file server machine.
Like the vos zap command, this command can remove a volume
that does not have a VLDB entry, as long as the volume is online,
-server and -partition arguments are provided, and the
-id argument specifies the volume's ID number.
- -server
<server name>
- Identifies the file server machine that houses the volume to remove. It is
necessary only when the -id argument names a read-only volume that
exists at multiple sites. 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) that houses the volume to remove. 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).
Including this argument is necessary only when the -id
argument names a read-only volume that exists at multiple sites. Provide
the -server argument along with this one.
- -id <volume name or
id>
- Identifies the volume to remove, either by its complete name or volume ID
number. If identifying a read-only or backup volume by name, include the
appropriate extension (".readonly" or
".backup").
- -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.
The following example removes the read/write volume
"user.terry" and its backup version, if
any.
% vos remove -id user.terry
The following example removes the read-only volume
"root.afs.readonly" from one of its sites,
the /vicepa partition on the file server machine
"fs1.example.com".
% vos remove fs1.example.com a root.afs.readonly
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".
