We are trying to use cephfs as storage for web graphics, such as
thumbnails and so on.
Is there any way to reduse overhead on storage? On test cluster we have
1 fs, 2 pools (meta and data) with replica size = 2
objects: 1.02 M objects, 1.1 GiB
usage: 144 GiB used, 27 GiB / 172 GiB avail
So we have (144/2)/1.1*100%=6500% overhead.
ceph version 13.2.1 (5533ecdc0fda920179d7ad84e0aa65a127b20d77) mimic
(stable)
osd storage - bluestore (changing bluestore_min_alloc_size makes no
visible effect)
You definitely should use S3 for this case, because S3 is Simple Storage
Service for web in first.
