在为Ceph集群创建新的OSD时，错误出现在/var/log/syslog中。这些症状是无声的，并且ansible显示以下错误：
monclient: authenticate NOTE: no keyring found; disabled cephx
authentication", "librados: client.admin authentication error (95)
Operation not supported", " stderr: [errno 95] error connecting to the cluster"

解决方案是固定主机上的资源限制。
$ vim /lib/systemd/system/ceph-osd@.service
查看限制
[Service]
LimitNOFILE=1048576
LimitNPROC=1048576
检查系统的最大限制。
# ulimit -a

data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 148786

重新加载systemctl守护程序
$ sudo systemctl daemon-reload
