vgexport changes a VG into the exported state, which ensures that the VG
|
|
and its disks are not being used, and cannot be used until the VG is
|
|
imported by \fBvgimport\fP(8). Putting a VG into an unusable, offline
|
|
state can be useful when doing things like moving a VG's disks to another
|
|
system. Exporting a VG provides some protection from its LVs being
|
|
accidentally used, or being used by an automated system before it's ready.
|
|
.P
|
|
A VG cannot be exported until all of its LVs are inactive.
|
|
.P
|
|
LVM commands will ignore an exported VG or report an error if a command
|
|
tries to use it.
|
|
.P
|
|
For an exported VG, the vgs command will display \"x\" in the third VG
|
|
attribute, and the pvs command will display \"x\" in the second PV
|
|
attribute. Both vgs and pvs will display \"exported\" from the export
|
|
report field.
|

|
|
vgexport clears the VG system ID, and vgimport sets the VG system ID to
|
|
match the host running vgimport (if the host has a system ID).
