-partition <partition name>
-name <volume name>
[-maxquota <initial quota (KB)>]
[-cell <cell name>]
[-noauth] [-localauth] [-verbose]
[-encrypt] [-noresolve] [-help]

-na <volume name> [-m <initial quota>]
[-c <cell name>] [-noa] [-l] [-v]
[-e] [-nor] [-h]
DESCRIPTION
The vos create command creates a read/write volume with the name specified by the -name
argument at the site specified by the -server and -partition arguments. In addition, the
command allocates or sets the following:
· 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.
· 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 fs mkmount
command. An entry that grants all seven permissions to the members of the
system:administrators group is automatically placed on the ACL. (In addition, the File
Server by default always implicitly grants the "l" (lookup) and "a" (administer)
permissions on every ACL to members of the system:administrators group, even when the
group does not appear on an ACL; use the -implicit argument to the fileserver
initialization command to alter the set of rights on a server-by-server basis if
desired.)
· The volume's space quota, set to 5000 kilobyte blocks by default. Use the -maxquota
argument to specify a different quota, or use the fs setquota command to change the
volume's quota after mounting the volume with the fs mkmount command.
The volume is empty when created. To access it via the Cache Manager, mount it in the file
space by using the fs mkmount command.
CAUTIONS
Currently, the maximum quota for a volume is 2 terabytes (2^41 bytes). Note that this only
affects the volume's quota; a volume may grow much larger if the volume quota is disabled.
However, volumes over 2 terabytes in size may be impractical to move, and may have their
size incorrectly reported by some tools, such as fs_listquota(1).
OPTIONS
-server <server name>
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 vos(1).
-partition <partition name>
Identifies the partition on which to create the read/write volume, on the file server
machine specified by the -server argument. 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).
-name <volume name>
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 ".backup" or ".readonly" 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.
-maxquota <initial quota>
Specifies the maximum amount of disk space the volume can use. The size should be a
positive integer followed by an optional suffix: "K" for kibibytes (1024 bytes, the
default), "M" for mebibytes (1024 kibibytes), "G" for gibibytes (1024 mebibytes), and
"T" for tebibytes (1024 gibibytes). The value 0 (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 "5000K".
-id <volume ID>
Specifies the volume ID for the read/write volume. If this options is not specified,
or the given volume ID is 0, a volume ID will be allocated for the volume
automatically. The volume IDs allocated should be fine for almost all cases, so you
should almost never need to specify this option.
-roid <readonly volume ID>
Specifies the volume ID for the readonly volume corresponding to the read/write volume
that is being created. The readonly volume will not be created; this merely specifies
what volume ID the readonly volume will use when it is created. If a volume ID of 0 is
specified here, no readonly volume ID will be assigned to the created volume
immediately. A readonly volume ID can still be assigned later when vos addsite is run;
if a volume does not have a readonly volume ID associated with it by the time vos
release is run, a volume ID will be allocated for it.
If this option is not specified, the default readonly volume ID is one number higher
than the read-write volume ID, whether or not that ID was manually specified.
As with the -id option, the default allocated volume IDs should be sufficient for
almost all cases, so you should almost never need to specify them explicitly. This
option is available in OpenAFS versions 1.5.61 or later.
-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.
-help
Prints the online help for this command. All other valid options are ignored.
OUTPUT
The Volume Server produces the following message to confirm that it created the volume:
Volume <volume_ID> created on partition <partition_name> of <machine_name>
EXAMPLES
The following command creates the read/write volume "user.pat" on the /vicepf partition of
the file server machine "fs4.abc.com".
% vos create -server fs4.abc.com -partition /vicepf -name user.pat
Volume user.pat created on partition /vicepf of fs4.abc.com
PRIVILEGE REQUIRED
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".
