Briefly, miserable.

All client IO was blocked.

36 pgs were stuck “down.”  pg query reported that they were blocked by
that OSD, despite that OSD not holding any replicas for them, with
diagnostics (now gone off of scrollback, sorry) about how bringing
that OSD online or marking it lost might resolve the issue.

With blocked IO and pgs stuck “down” I was not at all comfortable
marking the OSD lost.

Both conditions resolved after taking the steps outlined in the post I
just made to ceph-users.

Thanks!
