Hi Anthony,
yes we are using replication, the lost space is calculated before it's
replicated.

EC profile is pretty standard
[root@s3db16 ~]# ceph osd erasure-code-profile ls
default
[root@s3db16 ~]# ceph osd erasure-code-profile get default
k=2
m=1
plugin=jerasure
technique=reed_sol_van
We use mainly ceph 14.2.18. There is an OSD host with 14.2.19 and one with
14.2.20
Object populations is mixed, but the most amount of data is in huge files.
We store our platforms RBD snapshots in it.
Cheers
Boris
