There were several different real and made-up hostnames and company names used throughout our documentation examples. The IETF has reserved "example.com" and other "example" TLDs for use in examples (RFC 2606). Replace almost all references to ABC Corporation, DEF Corporation, and State University, as well as "abc.com", "bigcell.com", "def.com", "def.gov", "ghi.com", "ghi.gov", "jkl.com", "mit.edu", "stanford.edu", "state.edu", "stateu.edu", "uncc.edu", and "xyz.com". Standardize on "Example Corporation", "Example Network", "Example Organization" (example.com, example.net, and example.org). The Scout documentation in the Admin Guide contains PNG images that contain the old cell names, so I left those references until the images can be replaced.

=head1 DESCRIPTION
|
|
|
|
The B<vos move> command moves the indicated read/write volume from its
|
|
current site (specified with the B<-fromserver> and B<-frompartition>
|
|
arguments) to the destination site (specified with the B<-toserver> and
|
|
B<-topartition> arguments). This command automatically removes the backup
|
|
copy from the current site, if it exists. To create a new backup volume at
|
|
the destination site, use the B<vos backup> command.
|
|
|
|
This command works on read/write volumes only. To move a read-only volume,
|
|
use the B<vos addsite> and B<vos release> commands to define a new
|
|
read-only site and release the volume contents to it, and then use the
|
|
B<vos remove> command to remove the previous read-only volume's definition
|
|
from the Volume Location Database (VLDB) and data from the partition. To
|
|
move a backup volume, use this command to move its read/write source and
|
|
then issue the B<vos backup> command.
|
|
|
|
Before executing this command, the B<vos> command interpreter initiates a
|
|
check that the destination partition contains enough space to house the
|
|
volume being moved. If there is not enough space, the move operation is
|
|
not attempted and the following message appears:
|
|
|
|
vos: no space on target partition <dest_part> to move volume <volume>
|
|
|
|
=head1 CAUTIONS
|
|
|
|
Unless there is a compelling reason, do not interrupt a B<vos move>
|
|
command in progress. Interrupting a move can result in one or more of the
|
|
following inconsistent states:
|
|
|
|
=over 4
|
|
|
|
=item *
|
|
|
|
There are two versions of the volume, one at the source site and one at
|
|
the destination site. (If this happens, retain the version identified by
|
|
the VLDB and use the B<vos zap> command to remove the other version.)
|
|
|
|
=item *
|
|
|
|
The backup version of the volume is stranded at the old site. (If this
|
|
happens, use the B<vos zap> command to remove it.)
|
|
|
|
=item *
|
|
|
|
The volume is off-line. (If this happens, run the B<bos salvage> command
|
|
to bring it back on line.)
|
|
|
|
=back
|
|
|
|
If the Ctrl-C interrupt signal is pressed while a vos move operation is
|
|
executing, the following message warns of the consequences and requests
|
|
confirmation of the kill signal:
|
|
|
|
SIGINT handler: vos move operation in progress
|
|
WARNING: may leave AFS storage and metadata in indeterminate state
|
|
enter second control-c to exit
|
|
|
|
To confirm termination of the operation, press Ctrl-C a second time; press
|
|
any other key to continue the operation.
|
|
|
|
Currently, the maximum size of a volume is 2 terabytes (2^31 bytes).
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-id> <I<volume name or ID>>
|
|
|
|
Specifies either the complete name or volume ID number of a read/write
|
|
volume.
|
|
|
|
=item B<-fromserver> <I<server name>>
|
|
|
|
Identifies the file server machine where the volume currently
|
|
resides. Provide the machine's IP address or its host name (either fully
|
|
qualified or using an unambiguous abbreviation). For details, see
|
|
L<vos(1)>.
|
|
|
|
=item B<-frompartition> <I<partition name>>
|
|
|
|
Names the partition where the volume currently resides. Provide the full
|
|
partition name (for, example, B</vicepa>) or one of the abbreviated forms
|
|
described in L<vos(1)>.
|
|
|
|
=item B<-toserver> <I<server name>>
|
|
|
|
Identifies the file server machine to which to move the volume. Provide
|
|
the machine's IP address or its host name (either fully qualified or using
|
|
an unambiguous abbreviation). For details, see L<vos(1)>.
|
|
|
|
=item B<-topartition> <I<partition name>>
|
|
|
|
Names the partition to which to move the volume. Provide the full
|
|
partition name (for, example, B</vicepa>) or one of the abbreviated forms
|
|
described in L<vos(1)>.
|
|
|
|
=item B<-live>
|
|
|
|
Avoids making a temporary copy of the volume during the move. This is
|
|
useful if the partition is full, but the administrator needs to move
|
|
volumes to a another partition or server to free up disk space. The
|
|
caveat is that the volume is locked during the entire operation
|
|
instead of the short time that is needed to make the temporary clone.
|
|
|
|
=item B<-cell> <I<cell name>>
|
|
|
|
Names the cell in which to run the command. Do not combine this argument
|
|
with the B<-localauth> flag. For more details, see L<vos(1)>.
|
|
|
|
=item B<-noauth>
|
|
|
|
Assigns the unprivileged identity C<anonymous> to the issuer. Do not
|
|
combine this flag with the B<-localauth> flag. For more details, see
|
|
L<vos(1)>.
|
|
|
|
=item B<-localauth>
|
|
|
|
Constructs a server ticket using a key from the local
|
|
F</usr/afs/etc/KeyFile> file. The B<vos> command interpreter presents it
|
|
to the Volume Server and Volume Location Server during mutual
|
|
authentication. Do not combine this flag with the B<-cell> argument or
|
|
B<-noauth> flag. For more details, see L<vos(1)>.
|
|
|
|
=item B<-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.
|
|
|
|
=item B<-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.
|
|
|
|
=item B<-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.
|
|
|
|
=item B<-help>
|
|
|
|
Prints the online help for this command. All other valid options are
|
|
ignored.
|
|
|
|
=back
|
|
|
|
=head1 EXAMPLES
|
|
|
|
The following example moves the volume C<user.smith> from the F</vicepb>
|
|
partition on the file server machine C<fs3.example.com> to the F</vicepg>
|
|
partition on the file server machine C<fs7.example.com>.
|
|
|
|
% vos move -id user.smith -fromserver fs3.example.com -frompartition b \
|
|
-toserver fs7.example.com -topartition g
|
|
|
|
=head1 PRIVILEGE REQUIRED
|
|
|
|
The issuer must be listed in the F</usr/afs/etc/UserList> file on the
|
|
machines specified with the B<-toserver> and B<-fromserver> arguments and
|
|
on each database server machine. If the B<-localauth> flag is included,
|
|
the issuer must instead be logged on to a server machine as the local
|
|
superuser C<root>.
