<P><STRONG>Description</STRONG>
|
|
<P>The <B>vos create</B> command creates a read/write volume with the name
|
|
specified by the <B>-name</B> argument at the site specified by the
|
|
<B>-server</B> and <B>-partition</B> arguments. In addition,
|
|
the command allocates or sets the following:
|
|
<UL>
|
|
<P><LI>Volume ID numbers for the read/write volume and its associated read-only
|
|
and backup volumes (this command does not actually create the latter two types
|
|
of volume). A volume ID number is an identification number guaranteed
|
|
to be unique within a cell.
|
|
<A NAME="IDX5632"></A>
|
|
<A NAME="IDX5633"></A>
|
|
<A NAME="IDX5634"></A>
|
|
<A NAME="IDX5635"></A>
|
|
<A NAME="IDX5636"></A>
|
|
<A NAME="IDX5637"></A>
|
|
<P><LI>An access control list (ACL) associated with the volume's root
|
|
directory, which takes the same name as volume's mount point when the
|
|
volume is mounted with the <B>fs mkmount</B> command. An entry that
|
|
grants all seven permissions to the members of the
|
|
<B>system:administrators</B> group is automatically placed on the
|
|
ACL. (In addition, the File Server by default always implicitly grants
|
|
the <B>l</B> (<B>lookup</B>) and <B>a</B> (<B>administer</B>)
|
|
permissions on every ACL to members of the
|
|
<B>system:administrators</B> group, even when the group does not
|
|
appear on an ACL; use the <B>-implicit</B> argument to the
|
|
<B>fileserver</B> initialization command to alter the set of rights on a
|
|
server-by-server basis if desired.)
|
|
<P><LI>The volume's space quota, set to 5000 kilobyte blocks by
|
|
default. Use the <B>-maxquota</B> argument to specify a different
|
|
quota, or use the <B>fs setquota</B> command to change the volume's
|
|
quota after mounting the volume with the <B>fs mkmount</B> command.
|
|
</UL>
|
|
<P>The volume is empty when created. To access it via the Cache
|
|
Manager, mount it in the file space by using the <B>fs mkmount</B>
|
|
command.
|
|
<P><STRONG>Options</STRONG>
|
|
<DL>
|
|
<P><DT><B>-server
|
|
</B><DD>Identifies the file server machine on which to create the read/write
|
|
volume. 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 which to create the read/write volume, on the
|
|
file server machine specified by the <B>-server</B> argument.
|
|
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><DT><B>-name
|
|
</B><DD>Specifies a name for the read/write volume. The maximum length is
|
|
22 characters, which can include any alphanumeric or punctuation
|
|
character. By convention, periods separate the fields in a name.
|
|
Do not apply the <B>.backup</B> or <B>.readonly</B>
|
|
extension to a read/write volume name; they are reserved for the Volume
|
|
Server to add to the read/write name when creating those backup and read-only
|
|
volumes respectively.
|
|
<P><DT><B>-maxquota
|
|
</B><DD>Specifies the maximum amount of disk space the volume can use, as a number
|
|
of kilobyte blocks (a value of <B>1024</B> is one megabyte). The
|
|
value <B>0</B> (zero) grants an unlimited quota, but the size of the disk
|
|
partition that houses the volume places an absolute limit on its size.
|
|
If this argument is omitted, the default value is <B>5000</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
|
|
</B><DD>Prints the online help for this command. All other valid options
|
|
are ignored.
|
|
</DL>
|
|
<P><STRONG>Output</STRONG>
|
|
<P>The Volume Server produces the following message to confirm that it created
|
|
the volume:
|
|
<PRE> Volume <VAR>volume_ID</VAR> created on partition <VAR>partition_name</VAR> of <VAR>machine_name</VAR>
|
|
|
|
</PRE>
|
|
<P><STRONG>Examples</STRONG>
|
|
<P>The following command creates the read/write volume
|
|
<B>user.pat</B> on the <B>/vicepf</B> partition of the file
|
|
server machine <B>fs4.abc.com</B>.
|
|
<PRE> % <B>vos create -server fs4.abc.com -partition /vicepf -name user.pat</B>
|
|
Volume user.pat created on partition /vicepf of fs4.abc.com
|
|
|
|
</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>.
