NAME

       vos_copy - Make a copy of a volume

SYNOPSIS

       vos copy [-id] <volume name or ID of source>
          [-fromserver] <machine name for source>
          [-frompartition] <partition name for source>
          [-toname] <volume name for new copy>
          [-toserver] <machine name for destination>
          [-topartition] <partition name for destination>
          [-offline] [-readonly] [-live] [-cell <cell name>]
          [-noauth] [-localauth] [-verbose] [-encrypt] [-help]

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 size of a volume is 2 terabytes (2^31 bytes) and
       the maximum size of a /vicepX partition on a fileserver is also 2
       terabytes. The fileserver will not report an error when it has access
       to a partition larger than 2 terabytes, but it will probably fail if
       the administrator attempts to use more than 2 terabytes of space. In
       addition, there are reports of erroneous disk usage numbers when vos
       partinfo or other OpenAFS disk reporting tools are used with partitions
       larger than 2 terabytes.

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.

       -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.

       -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".
