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".
    % vos copy test server1  a test2 server1 a -cell localcell -verbose

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".
