任意一台节点运行
cephadm bootstrap --mon-ip 192.168.139.91
根据提示登录控制台并修改初始密码
添加节点
ssh-copy-id -f -i /etc/ceph/ceph.pub root@ceph-2 ssh-copy-id -f -i /etc/ceph/ceph.pub root@ceph-3 ceph orch host add ceph-2 ceph orch host add ceph-3 ceph orch host ls
添加OSD
查看集群可用设备
ceph orch device ls --wide Hostname Path Type Transport RPM Vendor Model Serial Size Health Ident Fault Available Reject Reasons ceph-1 /dev/sdb hdd Unknown Unknown VMware, VMware Virtual S 214G Unknown N/A N/A Yes ceph-2 /dev/sdb hdd Unknown Unknown VMware, VMware Virtual S 214G Unknown N/A N/A Yes ceph-3 /dev/sdb hdd Unknown Unknown VMware, VMware Virtual S 214G Unknown N/A N/A Yes
如需初始化磁盘设备
orch device zap <hostname> <path> [--force]
添加osd设备
ceph orch daemon add osd ceph-1:/dev/sdb ceph orch daemon add osd ceph-2:/dev/sdb ceph orch daemon add osd ceph-3:/dev/sdb
