ceph mds服务启动centos 7失败
ceph mds service fails to start centos 7
我正在尝试在 Centos 7 上的 Ceph Nautilus 14.2.19 上手动创建 ceph-mds。
首先,我以 <clusterid>-mds.<hostid>
的格式在 /var/lib/ceph/mds
中创建了一个文件夹
然后 运行 以下命令:
ceph-authtool --create-keyring /var/lib/ceph/mds/ceph-mds.<hostid>/keyring --gen-key -n mds.<hostid>
ceph auth add mds.<hostid> osd "allow rwx" mds "allow *" mon "allow profile mds" -i /var/lib/ceph/mds/ceph-mds.<hostid>/keyring
然后我将 /var/lib/ceph/mds/
内容的用户权限更改为 ceph:ceph
。
当我检查密钥环和在 ceph auth list
上为 mds 添加的密钥环时,我可以确认它们是匹配的。
但是当我 运行 systemctl 启动 ceph-mds@mds 时。守护进程没有启动,在 journalctl 上我得到以下错误输出:
Apr 20 11:38:14 <hostid> ceph-mds[44742]: 2021-04-20 11:38:14.592 7f53bcaef700 -1 monclient(hunting): handle_auth_bad_method server allowed_methods [2] but i only support [2]

这可能是什么原因?
已解决。显然问题是因为 /var/lib/ceph/mds
中的目录命名错误。更改并重新启动服务后,它已修复。
