That's right. The "remove" versus "unlink" verbs make that pretty clear
to me, at least... Are you suggesting this be clarified in the docs, or
that the command set change? I think once we settle on the CLI, John can
make a pass through the crush docs and make sure these commands are
explained.
That makes sense if you know the internal representation of the
CRUSH map; less so if you're thinking of it in terms from related fields like,
say, a filesystem. ;) I admit I don't have any better suggestions and
strong docs might be just fine, but the distinction is one that's very
visible to users *afterwards* but not beforehand. I'm imagining a lot of
crush maps with 5 unlinked parallel trees in our future.
I'm not saying it's better, but perhaps/possibly connect/disconnect?
