I have a 10-disk raid10 with a missing device I'm trying to replace. I get this error when doing it though: btrfs replace start 1 /dev/bcache0 /mnt ERROR: target device smaller than source device (required 1000203091968 bytes) I see that people recommend resizing a disk before replacing it, which isn't an option for me because it's gone. I'm replacing the drive by copying from its mirror, so can I resize the mirror and then replace? How do I do that? Do I need to run "btrfs fi res" on each of the remaining drives in the array?
