使用autofs自动挂载cephfs（kernel mount）

autofs挂载ceph-fuse（kernel mount cephfs）

安装autofs

root@ceph-1:~# apt-get install -y autofs
root@ceph-1:~# mkdir -p /cephfs/mds

编译配置文件

root@ceph-1:~# grep key /etc/ceph/ceph.client.admin.keyring  | cut -d= -f2-
 AQBr/HJjT9+QAhAAwPlUCQcitZwMeiw8O+Uzog==

root@ceph-1:~# vim /etc/ceph/autofs-admin.keyring
AQBr/HJjT9+QAhAAwPlUCQcitZwMeiw8O+Uzog==

root@ceph-1:~/autofs# chmod 600 /etc/ceph/autofs-admin.keyring 

root@ceph-1:~# vim /etc/auto.misc
mds -fstype=ceph,name=admin,secretfile=/etc/ceph/autofs-admin.keyring,noatime 192.168.3.52:/

root@ceph-1:~# vim /etc/auto.master 
/cephfs /etc/auto.misc --timeout 60

重启autofs服务

root@ceph-1:~# systemctl restart autofs && systemctl enable autofs && systemctl status autofs

测试自动挂载

root@ceph-1:~# df -Th
