Running "tune2fs -I 256 /dev/sda1" where /dev/sda1 is reasonably big (say 100gb) and doesn't already have 256 byte inodes takes a LONG time. On my system, it's been running at full CPU for over 3 days non-stop. Reproducible: Always Steps to Reproduce: 1. Run "tune2fs -I 256 /dev/sda1" on a reasonably big (say 100gb) sda1 that doesn't already have 256 byte inodes Actual Results: A *long* wait Expected Results: A relatively short wait (perhaps a couple hours? I'm not exactly sure) from http://marc.info/?l=linux-ext4&m=122672822822037&w=2 tune2fs: Fix inefficient O(n**2) algorithms when expanding the inode size When running "tune2fs -I 256" on moderate to large filesystems, the time required to run tune2fs can take many hours (20+ before some users gave up in disgust). This was due to some O(n**2) and O(n*m) algorithms in move_block() and inode_scan_and_fix(), respectively.

Which version of sys-fs/e2fsprogs do you use?
I'm using e2fsprogs-1.41.3 (the latest in portage right now, and the latest released version).
added patch from upstream git to 1.41.3-r1 http://sources.gentoo.org/sys-fs/e2fsprogs/files/e2fsprogs-1.41.3-tune2fs-opt.patch?rev=1.1
