Hi all, My ceph OSDs is running on Fedora-server24 with config are: 128GB RAM DDR3, CPU Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz, 72 OSDs (8TB per OSD). My cluster was use ceph object gateway with S3 API. Now, it had contained 500GB data but it was used > 50GB RAM. I'm worry my OSD will dead if i continue put file to it. I had read "OSDs do not require as much RAM for regular operations (e.g., 500MB of RAM per daemon instance); however, during recovery they need significantly more RAM (e.g., ~1GB per 1TB of storage per daemon)." in Ceph Hardware Recommendations. Someone can give me advice on this issue? Thank
