Volume Group, properties

• When one activates a volume group, all its LV and FS’s become visible (lsfs -c) and usable (‘mountable”).

• After importing a VG, you have to reset ownership of raw devices LV

• Do not confuse:

  • varyoffvg disables the VG locally
  • exportvg erases the local definition (kept in the ODM database) of the VG, LV and FS. In some cases the modification of the VG on the one other member requires reimporting the VG (eg: addition of new disk to a VG)
  • exportvg doesn’t format the disk
