Sakis cpu is no issue in current ceph bluestone on my cluster

Thx for this hint ! but i'm still stuck .... I modified ceph.conf ms_type=async+rdma ms_cluster_type = async+rdma ms_async_rdma_device_name=mlx4_0 [\code] and NO GID parameter ! because ceph.conf is common to all nodes and each node has a distinct GID ... or am i wrong ? root@pve01:~#...

fabian, thanks for response, but we have no error in regular operations. i only have problems to activate RDMA, to optimize OSD bluestore operations .... Is no customer known, operating mellanox equipment with proxmox 5 and RDMA over ethernet, not infiniband ... ?

alex and please someone @dietmar ... I have no glue how to get rdma working on strech ! for example rping does not work ... rping -s -v 192.168.100.141 rdma_create_event_channel: No such device ifconfig ens1d1 ens1d1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9000 inet...

consider upgrade to pve5! also bluestore in ceph is exiting ! btw i operate port1 with public network connectet to sx1012 switch and ceph on port2 on same switch but these ports are tagged as vlan on switch... no need to have vlan on port2 for ceph ... I found multicast might be a problem if...

might be a issue with flow control on card and on switch ... please check these settings i have no problems on pve5 and stretch and x3-pro running on 56Mbit and mellanox switch ... see my signature .. I updated firmware of x3-pro to latest and all things are smooth :)

try switching off any of these: tso, gro, gso, and lro example: ethtool -K <ethx> lro off

maybe these settings must be done ? https://community.mellanox.com/docs/DOC-2693 ... Open /etc/security/limits.conf and add the following lines to ping the memory.The RDMA is tightly coupled with the physical memory address. * soft memlock unlimited * hard memlock unlimited root soft...

same cluster but now bluestore, Tom! some 10% better performance! I think with RDMA enabled we will gain another 10% to 20% speedup but I still have no glue how to accomplish RDAM with ceph and underlying 56 Gbit Mellanox 3x cards .... rados bench -p test 60 write --no-cleanup -t 256 hints =...

may be a solution, but how does LiveMigration deal with this ? i think it's even not possible because of local resources....

sorry we only have windows and debian/ubuntu vm's .... no CentOS
