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.
-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.
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.example.com".
% vos create -server fs4.example.com -partition /vicepf -name user.pat
Volume user.pat created on partition /vicepf of fs4.example.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".
