35 The B<vos move> command moves the indicated read/write volume from its
36 current site (specified with the B<-fromserver> and B<-frompartition>
37 arguments) to the destination site (specified with the B<-toserver> and
38 B<-topartition> arguments). This command automatically removes the backup
39 copy from the current site, if it exists. To create a new backup volume at
40 the destination site, use the B<vos backup> command.
42 This command works on read/write volumes only. To move a read-only volume,
43 use the B<vos addsite> and B<vos release> commands to define a new
44 read-only site and release the volume contents to it, and then use the
45 B<vos remove> command to remove the previous read-only volume's definition
46 from the Volume Location Database (VLDB) and data from the partition. To
47 move a backup volume, use this command to move its read/write source and
48 then issue the B<vos backup> command.
50 Before executing this command, the B<vos> command interpreter initiates a
51 check that the destination partition contains enough space to house the
52 volume being moved. If there is not enough space, the move operation is
53 not attempted and the following message appears:
55 vos: no space on target partition <dest_part> to move volume <volume>
59 Unless there is a compelling reason, do not interrupt a B<vos move>
60 command in progress. Interrupting a move can result in one or more of the
61 following inconsistent states:
67 There are two versions of the volume, one at the source site and one at
68 the destination site. (If this happens, retain the version identified by
69 the VLDB and use the B<vos zap> command to remove the other version.)
73 The backup version of the volume is stranded at the old site. (If this
74 happens, use the B<vos zap> command to remove it.)
78 The volume is off-line. (If this happens, run the B<bos salvage> command
79 to bring it back on line.)
83 If the Ctrl-C interrupt signal is pressed while a vos move operation is
84 executing, the following message warns of the consequences and requests
85 confirmation of the kill signal:
87 SIGINT handler: vos move operation in progress
88 WARNING: may leave AFS storage and metadata in indeterminate state
89 enter second control-c to exit
91 To confirm termination of the operation, press Ctrl-C a second time; press
92 any other key to continue the operation.

100 =item B<-id> <I<volume name or ID>>
102 Specifies either the complete name or volume ID number of a read/write
105 =item B<-fromserver> <I<server name>>
107 Identifies the file server machine where the volume currently
108 resides. Provide the machine's IP address or its host name (either fully
109 qualified or using an unambiguous abbreviation). For details, see
112 =item B<-frompartition> <I<partition name>>
114 Names the partition where the volume currently resides. Provide the full
115 partition name (for, example, B</vicepa>) or one of the abbreviated forms
116 described in L<vos(1)>.
118 =item B<-toserver> <I<server name>>
120 Identifies the file server machine to which to move the volume. Provide
121 the machine's IP address or its host name (either fully qualified or using
122 an unambiguous abbreviation). For details, see L<vos(1)>.
124 =item B<-topartition> <I<partition name>>
126 Names the partition to which to move the volume. Provide the full
127 partition name (for, example, B</vicepa>) or one of the abbreviated forms
128 described in L<vos(1)>.
132 Avoids making a temporary copy of the volume during the move. This is
133 useful if the partition is full, but the administrator needs to move
134 volumes to a another partition or server to free up disk space. The
135 caveat is that the volume is locked during the entire operation
136 instead of the short time that is needed to make the temporary clone.
