Yeah, looks quite doable to handle some of these cases in RCU-walk mode. The main limitation is that you can't sleep ... Jeff Layton

Depends on what you mean by "support" - rbd CLI tool won't attempt to mess with your multipath settings ;) Ilya Dryomov
01:17 PM Bug #12763: rbd: unmap failed: (16) Device or resource busy
Thanks, Ilya,
This workaround works for me. So, there is no support for multipath from the rbd side, right?

11:44 AM Bug #12763: rbd: unmap failed: (16) Device or resource busy
This is likely a bug in either multipathd configuration or udev rules. Either way, not an rbd kernel client issue - ... Ilya Dryomov
