(Don't btrfs device delete, this >> would remove the copy. Just disconnect.) Hmm... Looking back at what I wrote... Presumably either have the filesystem unmounted for the disconnect (and ideally, the system off, tho with modern drives in theory that's not an issue, but still good if it can be done), or at least remounted read-only. I had guessed that was implicit, but making it explicit is probably best all around, just in case. At least I can rest better with it, having made that explicit. -- Duncan - List replies preferred.
