Ouy of curiosity, was there a reason you chose those particular file system parameters? It's a surprising set, because if you're starting with a fresh file system, enabling flex_bg produces a more optimal file system layout. The reason why I wrote the commit description way I did was because it seemed to be the most likely way that someone would trip across this bug. We didn't notice this for as long as we did since most of the users of ext4 (especially those who use community distributions) have been using freshly mkfs'ed ext4 file systems. - Ted -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
