Title:
  resize2fs does not expand filesystem; no error messages are displayed

Status in “e2fsprogs” package in Ubuntu:
  New

Bug description:
  Assuming /dev/mapper/system-backup has 50GB of space ...

  1. Expand an LVM volume with lvextend:
  lvextend -L +50G /dev/mapper/system-backup

  2. Resize the filesystem:
  resize2fs  /dev/mapper/system-backup

  All seems OK, no warning or error message will be displayed. No errors in syslog, too.
  BUT the filesystem is only 50G big, the additional 50G will not be available.

  df -h will tell you, that there is 50GB of free space, but if you try
  to use this space, you will see the error: "filesystem full".

  This bug exists at least since Ubuntu 10.10! Ubuntu 12.04.1 is also
  affected!
