Best practices for partitioning and LVM usage with future storage growth in mind?

Solution Unverified - Updated -


  • Is it supported to use a whole multipathed disk and write a "simple protective MBR" (cf. Wikipedia on GUID Partition Table) with fdisk after pvcreate?
  • I want to be prepared for future storage growth:
    • I want to use LVM.
    • I want to be able to resize the underlying storage and have the LVM setup adapt to that.
    • The underlying storage is multipathed.
    • I want to use a protective MBR to signal that the storage is in use and to prevent foreign OS installers from considering the storage as available.


  • Red Hat Enterprise Linux (RHEL) 6.3
  • Resizeable storage devices (for example, Fibre Channel Storage Area Network (SAN) LUNs)
  • Logical Volume Management (LVM)
