- ceph中兩種類型分區的type code:
| type | type code |
|---|---|
| journal | 45b0969e-9b03-4f30-b4c6-b4b80ceff106 |
| osd |
4fbd7e29-9d25-41b8-afd0-062c0ceff05d |
- 有人會好奇為啥要給分區設置固定的uuid呢，原因是ceph通過uuid來區分你是osd分區還是journal分區之後，再決定數據放在哪裏
- 參考文檔有解釋：http://www.cnblogs.com/gzxbkk/p/7737421.html

總結:
ceph中創建journal分區和data分區：
sgdisk -n {part num}:0:+{part size}G {disk} -t {part num}:4fbd7e29-9d25-41b8-afd0-062c0ceff05d -c {part num}:”ceph data”
sgdisk -n {part num}:0:+{part size}G {disk} -t {part num}:45b0969e-9b03-4f30-b4c6-b4b80ceff106 -c {part num}:”ceph journal” -
