We should get this reported to Ceph upstream.
Ceph is bundling an old copy of rocksdb (ugh), and I wonder if this is
fixed in a later version of rocksdb.
By the way, my hunch is that the reason that Ceph bundles rocksdb is
because it was not packaged in the distros at the time that Ceph wanted
to use it.
Exactly.
Is it now packaged in Ubuntu?
Nope!
Let's pull rocksdb up to a newer version and see if that helps?
