@Williams,
Sorry for late reply. I'm busy on working getting Ceph/RDMA
performance data these days.
I'm using Intel RDMA NIC with small cluster, there's no serious issue
happened.
For Mellanox NIC, there's no problem with your ceph.conf from my perspective.
Below is the steps that I used to deploy cluster
1. server0: 172.16.1.4, /dev/nvme0n1, /dev/nvme1n1
2. server1: 172.16.1.2, /dev/nvme0n1, /dev/nvme1n1
Below is my deploy steps:
[admin@server0 deploy]$ ceph-deploy new server0 --fsid 24280750-d4f7-4d4f-89e4-f95b8fab87ff
[admin@server0 deploy]$ #change ceph.conf as below:
[admin@server0 deploy]$ cat ceph.conf
[global]
cluster = ceph
fsid = 24280750-d4f7-4d4f-89e4-f95b8fab87ff
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
osd pool default size = 2
osd pool default min size = 2
osd pool default pg num = 64
osd pool default pgp num = 128
osd pool default crush rule = 0
osd crush chooseleaf type = 1
mon_allow_pool_delete=true
osd_pool_default_pg_autoscale_mode=on
ms_type = async+rdma
;----changcheng: change device to your dev name----------
ms_async_rdma_device_name = irdma1
;----changcheng: ignore below parameters with Mellanox NIC--------
;ms_async_rdma_support_srq = false
mon_initial_members = server0
mon_host = 172.16.1.4
[mon.rdmarhel0]
host = server0
mon addr = 172.16.1.4
[admin@server0 deploy]$ ceph-deploy mon create-initial
[admin@server0 deploy]$ ceph-deploy admin server0 server1
[admin@server0 deploy]$ ceph-deploy mgr create server0
[admin@server0 deploy]$ ceph-deploy osd create --data /dev/nvme0n1 server0
[admin@server0 deploy]$ ceph-deploy osd create --data /dev/nvme1n1 server0
[admin@server0 deploy]$ ceph-deploy osd create --data /dev/nvme0n1 server1
[admin@server0 deploy]$ ceph-deploy osd create --data /dev/nvme1n1 server1
