Subject: error ext4_mb_generate_buddy:726 & add_dirent_to_buf:1272 after online resize

hi

I'm getting these errors on my home filesystem

[ 5147.616006] EXT4-fs (dm-28): error count: 11
[ 5147.616888] EXT4-fs (dm-28): initial error at 1295177566: ext4_mb_generate_buddy:726
[ 5147.617827] EXT4-fs (dm-28): last error at 1295177566: add_dirent_to_buf:1272: inode 262145: block 1048578

I have done a fsck -f and that didn't make them stop. The errors started a few minutes
after I did an online resize of my filesystem.

To resize the filesystem I did something like this:

	lvextend --size +14G vg_root/stuart
	cryptsetup resize _dev_dm_21
	resize2fs  /dev/mapper/_dev_dm_21

It took me a couple of attemps to find the correct arguments for the "cryptsetup resize" but I don't think I broke anything. When I saw the errors from "mv" at 12:32:46 I unmounted the filesystem and did a fsck. That corrected some errors but I'm still getting "ext4_mb_generate_buddy:726" and "add_dirent_to_buf:1272" errors.

The filesystem in question is an encrypted partition on top of a lvm partition on a SSD.

thanks
Stuart
