Hi Ted, Andreas and List, As Andreas pointed out last year, if the last group is the 1st group in a meta bg, then its group desc has no backup. With meta_bg resizing inode is useless, I had a thought that we store a backup group descriptor of the last group in the resizing inode? What's your opinions?
