Cheers, - Ted commit c5c72d814cf0f650010337c73638b25e6d14d2d4 Author: Theodore Ts'o <tytso@....edu> Date: Sun Apr 21 20:19:43 2013 -0400 ext4: fix online resizing for ext3-compat file systems Commit fb0a387dcdc restricts block allocations for indirect-mapped files to block groups less than s_blockfile_groups. However, the online resizing code wasn't setting s_blockfile_groups, so the newly added block groups were not available for non-extent mapped files.
