Date: Wed, 11 Apr 2007 15:17:26 -0500 From: Eric Sandeen <sandeen@...hat.com> To: ext4 development <linux-ext4@...r.kernel.org> Subject: debugfs fill_bgs command? I was wondering if others think it would be useful to have a "fill_bgs" command in debugfs; this would (minimally) mark the lower X bgs as full for both inodes & blocks (possibly either/or), to allow testing the higher block groups. I'm using a hacked up version of this to do a little ext3 testing above 8T. Given that this would really only be a testing option in nature, would it be accepted into e2fsprogs? I'd probably need some sort of "unfill" command as well, to put the bg counters back where they should be; probably by actually reading the bitmaps. This way fsck would still find a consistent filesystem... I had originally written a set_bg_field function too, to go with inode & sb variants, though for marking the first few thousand bg's it was going to get a bit tedious... :) Thoughts?
