|
<P><STRONG>Description</STRONG>
|
|
<P>The <B>vos remove</B> 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.
|
|
<UL>
|
|
<P><LI>If the <B>-id</B> 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
|
|
<B>-server</B> and <B>-partition</B> 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 <B>vos
|
|
listvldb</B> or <B>vos examine</B> 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 <B>vos examine</B> and <B>vos listvldb</B> commands as
|
|
<TT>number of sites</TT> decrements by one. The entire VLDB entry is
|
|
removed if there are no read-only sites.
|
|
<P><LI>If the <B>-id</B> 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 <B>vos
|
|
examine</B> and <B>vos listvldb</B> commands as <TT>number of
|
|
sites</TT> decrements by one for each volume you remove. If there is
|
|
more than one read-only site, the <B>-server</B> argument (and optionally
|
|
<B>-partition</B> argument) must be used to specify the site from which to
|
|
remove the volume. If there is only one read-only site, the
|
|
<B>-id</B> argument is sufficient; if there is also no read/write
|
|
volume in this case, the entire VLDB entry is removed.
|
|
<P><LI>If the <B>-id</B> argument names a backup volume, it is removed from
|
|
the partition that houses it. The <B>-server</B> and
|
|
<B>-partition</B> arguments are optional, because there can be only one
|
|
backup site. The backup volume ID number no longer appears in the
|
|
output from the <B>vos listvldb</B> command or in the corresponding
|
|
portion of the output from the <B>vos examine</B> command, but is
|
|
preserved internally.
|
|
</UL>
|
|
<P>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 <B>vos delentry</B>, <B>vos remsite</B> and <B>vos
|
|
zap</B> 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 <B>vos delentry</B> command, this command
|
|
can remove a VLDB entry when no corresponding volumes exist on the file server
|
|
machine. Like the <B>vos zap</B> command, this command can remove a
|
|
volume that does not have a VLDB entry, as long as the volume is online,
|
|
<B>-server</B> and <B>-partition</B> arguments are provided, and the
|
|
<B>-id</B> argument specifies the volume's ID number.
|
|
<P><STRONG>Options</STRONG>
|
|
<DL>
|
|
<P><DT><B>-server
|
|
</B><DD>Identifies the file server machine that houses the volume to
|
|
remove. It is necessary only when the <B>-id</B> 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 the introductory reference
|
|
page for the <B>vos</B> command suite.
|
|
<P><DT><B>-partition
|
|
</B><DD>Identifies the partition (on the file server machine specified by the
|
|
<B>-server</B> argument) that houses the volume to remove. Provide
|
|
the partition's complete name with preceding slash (for example,
|
|
<B>/vicepa</B>) or use one of the three acceptable abbreviated
|
|
forms. For details, see the introductory reference page for the
|
|
<B>vos</B> command suite.
|
|
<P>Including this argument is necessary only when the <B>-id</B> argument
|
|
names a read-only volume that exists at multiple sites. Provide the
|
|
<B>-server</B> argument along with this one.
|
|
<P><DT><B>-id
|
|
</B><DD>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 (<B>.readonly</B> or
|
|
<B>.backup</B>).

|
|
<P><DT><B>-cell
|
|
</B><DD>Names the cell in which to run the command. Do not combine this
|

argument with the <B>-localauth</B> flag. For more details, see the
|
|
introductory <B>vos</B> reference page.
|
|
<P><DT><B>-noauth
|
|
</B><DD>Assigns the unprivileged identity <B>anonymous</B> to the
|

issuer. Do not combine this flag with the <B>-localauth</B>
|
|
flag. For more details, see the introductory <B>vos</B> reference
|
|
page.
|
|
<P><DT><B>-localauth
|
|
</B><DD>Constructs a server ticket using a key from the local
|
|
<B>/usr/afs/etc/KeyFile</B> file. The <B>vos</B> command
|
|
interpreter presents it to the Volume Server and Volume Location Server during
|
|
mutual authentication. Do not combine this flag with the
|
|
<B>-cell</B> argument or <B>-noauth</B> flag. For more details,
|
|
see the introductory <B>vos</B> reference page.
|
|
<P><DT><B>-verbose
|
|
</B><DD>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.

<P><DT><B>-help

are ignored.

<P><STRONG>Examples</STRONG>
|
|
<P>The following example removes the read/write volume
|
|
<B>user.terry</B> and its backup version, if any.
|
|
<PRE> % <B>vos remove -id user.terry</B>
|
|
|
|
</PRE>
|
|
<P>The following example removes the read-only volume
|
|
<B>root.afs.readonly</B> from one of its sites, the
|
|
<B>/vicepa</B> partition on the file server machine
|
|
<B>fs1.abc.com</B>.
|
|
<PRE> % <B>vos remove fs1.abc.com a root.afs.readonly</B>
|
|
|
|
</PRE>
|
|
<P><STRONG>Privilege Required</STRONG>
|
|
<P>The issuer must be listed in the <B>/usr/afs/etc/UserList</B> file on
|
|
the machine specified with the <B>-server</B> argument and on each
|
|
database server machine. If the <B>-localauth</B> flag is included,
|
|
the issuer must instead be logged on to a server machine as the local
|
|
superuser <B>root</B>.
