创建osd

所有存储节点执行相同操作

1.列出节点磁盘信息

ceph-deploy disk list ceph01
ceph-deploy disk list ceph02
ceph-deploy disk list ceph03

输出如下

...

其中/dev/sda-hSSD类型磁盘,且/dev/sda为系统盘

2.查看磁盘挂载

lsblk

输出如下

NAME              MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda                 8:16   0 894.3G  0 disk

sdh                 8:112  0 894.3G  0 disk
....

3.格式化磁盘

mkfs.ext4 /dev/sdb
mkfs.ext4 /dev/sdc
mkfs.ext4 /dev/sdd
mkfs.ext4 /dev/sde
mkfs.ext4 /dev/sdf
mkfs.ext4 /dev/sdg
mkfs.ext4 /dev/sdh

4.擦净节点磁盘

cd /etc/ceph/
for i in {b..h};do
ceph-deploy disk zap ceph01 /dev/sd$i
done

cd /etc/ceph/
for i in {b..h};do
ceph-deploy disk zap ceph02 /dev/sd$i
done

cd /etc/ceph/
for i in {b..h};do
ceph-deploy disk zap ceph03 /dev/sd$i
done

5.创建osd节点

cd /etc/ceph
for i in {b..h};do
  ceph-deploy osd create --data /dev/sd$i ceph01
done

cd /etc/ceph
for i in {b..h};do
  ceph-deploy osd create --data /dev/sd$i ceph02
done

cd /etc/ceph
for i in {b..h};do
  ceph-deploy osd create --data /dev/sd$i ceph03
done
