lvextend --resize does not resize ext4 based underlying filesystem

Solution Verified - Updated -

Issue

  • After executing the 'lvextend' command with the '-r' option:
#lvextend -L <size> -r -v /name/of/logical-volume
  • The ext4 filesystem should Auto-resize itself instead of manually performing 'resize2fs' after performing 'lvextend'.
  • While checking for filesystem features:
# tune2fs -l /name/of/logical-volume
tune2fs 1.39 (29-May-2006)
tune2fs: Filesystem has unsupported feature(s) while trying to open /name/of/logical-volume
Couldn't find valid filesystem superblock.

Environment

  • Red Hat Enterprise Linux (RHEL5)
  • Logical Volume Manager (LVM2) managed volumes
    • LVM2 version prior to lvm2-2.02.88-7.el5
  • Ext4 filesystem
