Re: Chicken-egg: uncorrectable checksum error prevents RAID1 rebalancing

My arrangement is two subvolumes, 'root' and 'home', directly under the root
subvolume. The 'root' subvolume is mounted on /, the 'home' subvolume on /home.
I've tried both pointing the find command at /, and mounting the root subvolume
on a mount directory and pointing it there. Neither show any file or directory
with inum 515.
