磁盘要求
新添加的磁盘只能是无分区或格式化文件系统,不能是lvm卷
修改发现磁盘扫描间隔
vim rook/deploy/examples/operator.yaml
# The duration between discovering devices in the rook-discover daemonset.
- name: ROOK_DISCOVER_DEVICES_INTERVAL
value: "60"
下发资源
kubectl apply -f rook/deploy/examples/operator.yaml
添加OSD磁盘
vim rook/deploy/examples/cluster.yaml
nodes:
# - name: "172.17.4.201"
# devices: # specific devices to use for storage can be specified for each node
# - name: "sdb"
# - name: "nvme01" # multiple osds can be created on high performance devices
# config:
# osdsPerDevice: "5"
# - name: "/dev/disk/by-id/ata-ST4000DM004-XXXX" # devices can be specified using full udev paths
# config: # configuration can be specified at the node level which overrides the cluster level config
# - name: "172.17.4.301"
# deviceFilter: "^sd."
# when onlyApplyOSDPlacement is false, will merge both placement.All() and placement.osd
- name: "master"
devices:
- name: "vdb"
- name: "vdc"
- name: "node"
devices:
- name: "vdb"
- name: "vdc"
- name: "node2"
devices:
- name: "vdb"
- name: "vdc"
onlyApplyOSDPlacement: false
下发资源
kubectl apply -f rook/deploy/examples/cluster.yaml

#新增了osd-3-5
[root@master ~]# kubectl get pod -n rook-ceph
