Hi Ted,

is offline resizeing possible with this patch without online resize 
kernel patches (i use 3.2.0) with this features?

Filesystem features:      has_journal ext_attr dir_index filetype 
needs_recovery meta_bg extent 64bit flex_bg sparse_super large_file 
huge_file uninit_bg dir_nlink extra_isize

I had no luck offline resizing my 24TB fs with e2fstools version 1.42 
and 1.42.5.

thx for your time.
