Extending root RHEL physical partition and then the underlying LV

Bit fiddly this so reminder to myself:
  • Boot into rescue mode from install DVD
  • delete partition with fdisk 
  • recreate at same start to end of disk
  • reboot
  • back into rescue
  • Then run these commands
pvresize /dev/sda2 (or 2nd partition on physical disk)
lvextend /dev/mapper/*vg_lv* -l+100%FREE (for all the disk)
resize2fs /dev/mapper/*vg_lv* (to resize FS, may take a short while)
  • Check volumes are ok with vgs/lvs
  • Reboot to double check everything boots and mounts fine
