Hi,
have a ceph cluster witch tree nodes and 32 osds. The tree nodes have 16Gb memory but only 5Gb is in use. Nodes are Dell Poweredge R510. my ceph.conf: [global] mon_initial_members = ceph01 mon_host = 10.0.0.20,10.0.0.21,10.0.0.22 auth_cluster_required = cephx auth_service_required = cephx auth_client_required = cephx filestore_xattr_use_omap = true filestore_op_threads = 32 public_network = 10.0.0.0/24 cluster_network = 10.0.1.0/24 osd_pool_default_size = 3 osd_pool_default_min_size = 1 osd_pool_default_pg_num = 4096 osd_pool_default_pgp_num = 4096 osd_max_write_size = 200 osd_map_cache_size = 1024 osd_map_cache_bl_size = 128 osd_recovery_op_priority = 1 osd_max_recovery_max_active = 1 osd_recovery_max_backfills = 1 osd_op_threads = 32 osd_disk_threads = 8 is that normal or a bottleneck? best regards Patrik
