It should work but it's better to use btrfs replace start for this sort of operation since it does all of that in one step. > As you can > see in my `btrfs fi sh` output below, my newly added drive (ID=6) has > the expected size of 5.46TiB, but my replaced drive (ID=4) won't show up > as 6TB as expected.

Not sure, this has always worked for me in the past, online. You could try unmounting and doing a btrfs dev scan, remounting, and then retrying the command. There's nothing in dmesg? There should be something there whether it succeeds or fails. -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
