Marcus,
You may want to look at the bluestore_min_alloc_size setting as well
Marcus,
You may want to look at the bluestore_min_alloc_size setting as well
as the respective bluestore_min_alloc_size_ssd and
bluestore_min_alloc_size_hdd. By default bluestore sets a 64k block
size for ssds. I'm also using ceph for small objects and I've see my
OSD usage go down from 80% to 20%
Don't forget that at those sizes the internal journals and rocksdb size
tunings are likely to be a significant fixed cost.

Hi,
we are doing some tests here with a Kraken setup using bluestore backend (on
Ubuntu 64 bit).

(no fs, no rdb, only osd and monitors)
The setup was done with ceph-deploy, using the standard bluestore option, no
separate device
