No i dont think so either, this was just a example. Maybe it is totaly

You could try setting up a pool with a replication level of 1 and see
how that does. It will be faster in any event, but it would be
interesting to see how much faster.
is there an easier way than modifying the crush map?

PS: i also tested noop scheduler - same result.

Stefan

something like:

ceph osd pool create POOL [pg_num [pgp_num]]

then:

ceph osd pool set POOL size VALUE
