  • Both the block device and multipath devices need to be resized
  • We need to extend our pv, vg, and lv which are using the entire device, not partitions
  • We need to extend the filesystem
  • Underlying device of the PV has been extended from storage end. How to get the additional size reflected in the PV, VG.


  • Red Hat Enterprise Linux 5, 6, 7 &8
