DESCRIPTION

       The vos copy command makes a copy of a volume with a new name.  It is equivalent to vos
       dump followed by vos restore, but doesn't require the volume be stored locally by the
       client.

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

       -id <volume name or ID>
           Specifies either the complete name or volume ID number of a read/write volume.

       -fromserver <machine name for source>
           Identifies the file server machine where the source volume resides. Provide the
           machine's IP address or its host name (either fully qualified or using an unambiguous
           abbreviation). For details, see vos(1).

       -frompartition <partition name for source>
           Names the partition where the source volume resides. Provide the full partition name
           (for, example, /vicepa) or one of the abbreviated forms described in vos(1).

       -toname <volume name for new copy>
           The complete name of the new volume to create.

       -toserver <machine name for destination>
           Identifies the file server machine to which to copy the volume.  Provide the machine's
           IP address or its host name (either fully qualified or using an unambiguous
           abbreviation). For details, see vos(1).

       -topartition <partition name for destination>
           Names the partition to which to copy the volume. Provide the full partition name (for,
           example, /vicepa) or one of the abbreviated forms described in vos(1).

       -offline
           Leaves the new volume flagged as off-line in the volume database.

       -readonly
           Flags the new volume as read-only in the volume database.

       -live
           Copies the live volume without cloning.  This is normally not necessary and causes the
           volume to be kept locked for longer than the normal copy mechanism.

       -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

       This command has no output unless "-verbose" is specified or there is an error.

EXAMPLES

       The following example makes a verbose copy of the "test" volume named "test2" in the cell
       "localcell". The volume and copy both reside on "/vicepa" of "server1".

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".
