> 说明：添加OSD时，建议将磁盘先格式化为无分区的原始磁盘
|
||
```shell
|
||
## https://rook.github.io/docs/rook/v1.10/Getting-Started/ceph-teardown/?h=sgdisk#zapping-devices
|
||
DISK="/dev/sdX"
|
||
|
||
## Zap the disk to a fresh, usable state (zap-all is important, b/c MBR has to be clean)
|
||
sgdisk --zap-all $DISK
|
||
|
||
## Wipe a large portion of the beginning of the disk to remove more LVM metadata that may be present
|
||
dd if=/dev/zero of="$DISK" bs=1M count=100 oflag=direct,dsync
|
||
|
||
## SSDs may be better cleaned with blkdiscard instead of dd
|
||
blkdiscard $DISK
|
||
|
||
## Inform the OS of partition table changes
|
||
partprobe $DISK
|
||
```
|
||
```shell
|
||
## 查看各ceph节点有哪些磁盘是可用的，关注`AVAILABLE`列
|
||
# ceph orch device ls
|
||

|
||
## 接下来初始化osd
|
||
## 将指定的磁盘格式化为无分区的原始磁盘
|
||
# blkdiscard /dev/nvme0n2
|
||
# cephadm shell ceph orch device zap ceph01 /dev/sda
|
||
## 接着初始化其他节点上磁盘
|
||
...
|
||
|
||
## 添加OSD
|
||
# ceph orch daemon add osd ceph01:/dev/nvme0n2
|
||
# ceph orch daemon add osd ceph01:/dev/sda
|
||
# ceph orch daemon add osd ceph02:/dev/nvme0n2
|
||
# ceph orch daemon add osd ceph02:/dev/sda
|
||
# ceph orch daemon add osd ceph03:/dev/nvme0n2
|
||
# ceph orch daemon add osd ceph03:/dev/sda
|
||
# ceph orch daemon add osd ceph04:/dev/nvme0n2
|
||
# ceph orch daemon add osd ceph04:/dev/sda
|
||
# ceph orch daemon add osd ceph05:/dev/nvme0n2
|
||
# ceph orch daemon add osd ceph05:/dev/sda
