錯誤一
執行ceph-deploy mon create-initial時報錯的原因
忘記沒有切換至my-cluster目錄下 切換至my-cluster目錄下重新執行就可以
ConfigError: Cannot load config: [Errno 2] No such file or directory: 'ceph.conf'; has ceph-deploy new been run in this directory?

錯誤二
執行ceph-deploy osd create --data /dev/sdb node1是報錯的原因沒有添加空的磁盤
[ceph_deploy.osd][ERROR ] Failed to execute command: /usr/sbin/ceph-volume --cluster ceph lvm create --bluestore --data /dev/sdb
[ceph_deploy][ERROR ] GenericError: Failed to create 1 OSDs

錯誤三
[cephu@centos7u3_1 my-cluster]$ ceph-deploy new node1
Traceback (most recent call last):
File "/bin/ceph-deploy", line 18, in
from ceph_deploy.cli import main
File "/usr/lib/python2.7/site-packages/ceph_deploy/cli.py", line 1, in
import pkg_resources
ImportError: No module named pkg_resources
重新安裝python的distribution：
下載 distribution :
https://pypi.python.org/pypi/distribute
cd distribution-0.7.3/
sudo python setup.py install
distribution下載地址：

錯誤四
[ERROR ] admin_socket: exception getting command descriptions: [Errno 2] No such file or dir
cat /etc/ceph/ceph.conf
添加
public_network= 192.168.122.0/24
推送
ceph-deploy --overwrite-conf config push admin node1 node2 node3

錯誤五：
ceph-deploy osd create --data /dev/vdc node3
[node1][WARNIN] ceph-volume lvm create: error: GPT headers found, they must be removed on: /dev/vdb
[node1][ERROR ] RuntimeError: command returned non-zero exit status: 2
[ceph_deploy.osd][ERROR ] Failed to execute command: /usr/sbin/ceph-volume --cluster ceph lvm create --bluestore --data /dev/vdb
[ceph_deploy][ERROR ] GenericError: Failed to create 1 OSDs
千萬不要分區，然后重新加磁盤，重新做
又文檔說加上參數也可以但是
ceph-deploy osd create --data /dev/vdc --fs-type xfs node3 不行
[cephu@node1 ~]$ sudo ceph auth get-or-create mgr.node1 mon 'allow profile mgr' osd 'allow *' mds 'allow *'
[mgr.node1]
key = AQD8HPdcmntqJRAAlZ3Aeialqq0nVcdcg+axqQ==
錯誤六
[ceph_deploy][ERROR ] RuntimeError: connecting to host: node1 resulted in errors: IOError cannot send (already closed?)

出現此錯誤是沒有設置免密碼如下設置
打開node的sudoers
vim /etc/sudoers
添加免密碼
abc ALL = NOPASSWD: ALL
