我正在尝试在Ceph Nautilus 14.2.19上的Centos 7上手动创建ceph-mds。首先,我在/var/lib/ceph/mds中创建了一个<clusterid>-mds.<hostid>格式的文件夹,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。当我检查密钥环和添加到ceph auth list上的密钥环的mds时,我可以确认它们是匹配的。但是,当我运行systemctl时,启动ceph-mds@mds。守护进程无法启动,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]

已解决。显然,这个问题是由于/var/lib/ceph/mds内部错误的目录命名造成的。在更改并重新启动服务之后,它被修复了。
