Unfortunately, there is still a bug in e2fsprogs > as my last email says. The following two patches were sufficient for me to resize a test file system from 14 TB to 18 TB. We still need to handle automatic enabling of the meta_bg flag in resize2fs, but this should be sufficient for more adventurous folks to test the online resize patches. (Note that I also posted a v2 version of patch 5/5 which fixed a number of 64-bit overflow bugs that I found in my testing.) - Ted
