            "content": "vgexport  changes  a  VG into the exported state, which ensures that the VG and its disks are\nnot being used, and cannot be used until the VG is imported by  vgimport(8).   Putting  a  VG\ninto  an  unusable, offline state can be useful when doing things like moving a VG's disks to\nanother system.  Exporting a VG provides some protection  from  its  LVs  being  accidentally\nused, or being used by an automated system before it's ready.\n\nA VG cannot be exported until all of its LVs are inactive.\n\nLVM commands will ignore an exported VG or report an error if a command tries to use it.\n\nFor  an exported VG, the vgs command will display attribute, and the pvs command will display\nattribute.  Both vgs and pvs will display report field.\n\nvgexport clears the VG system ID, and vgimport sets the VG system ID to match the  host  run‐\nning vgimport (if the host has a system ID).\n",
