vos create - Creates a read/write volume and associated VLDB entry


vos create -server <machine name> -partition <partition name> -name <volume name> [-maxquota <initial quota (KB)>] [-cell <cell name>] [-noauth] [-localauth] [-verbose] [-help]

vos cr -s <machine name> -p <partition name> -na <volume name> [-m <initial quota (KB)>] [-c <cell name>] [-no] [-l] [-v] [-h]


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:

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.


-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 <volume quota>

Specifies the maximum amount of disk space the volume can use, as a number of kilobyte blocks (a value of 1024 is one megabyte). 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 5000.

-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).


Assigns the unprivileged identity anonymous to the issuer. Do not combine this flag with the -localauth flag. For more details, see vos(1).


Constructs a server ticket using a key from the local /usr/afs/etc/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).


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.


Prints the online help for this command. All other valid options are ignored.


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>


The following command creates the read/write volume user.pat on the /vicepf partition of the file server machine

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


The issuer must be listed in the /usr/afs/etc/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.
