Are you sure can you really use 3.2 for
nautilus?

_______________________________________________Ceph-ansible 3.2, rolling upgrade mimic -> nautilus. The ansible file sets flag "norebalance". When there is*no* I/O to the cluster, upgrade works fine. When upgrading with IO running in the background, some PG become `active+undersized+remapped+backfilling`
Flag norebalance prevents them from backfilling / recovering and upgrade fails. I'm uncertain why those OSD are "backfilling" instead of "recovering" but I guess it doesn't matter, norebalance halts the process.
setting ceph tell osd.* injectargs '--osd_max_backfills=2 made no difference
