1、报错信息
启动glusterfs文件系统报错，根据网上的排错，基本都是删除glusterfs的数据目录，然并卵。
报错如下：
[root@k8s-node2 ~]# systemctl status glusterd.service
● glusterd.service - GlusterFS, a clustered file-system server
Loaded: loaded (/usr/lib/systemd/system/glusterd.service; disabled; vendor preset: disabled)
Active: failed (Result: exit-code) since Sat 2021-05-15 15:39:08 CST; 4s ago
Docs: man:glusterd(8)

May 15 15:39:08 k8s-node2 systemd[1]: Failed to start GlusterFS, a clustered file-system server.
May 15 15:39:08 k8s-node2 systemd[1]: Unit glusterd.service entered failed state.
May 15 15:39:08 k8s-node2 systemd[1]: glusterd.service failed.
测试集群配置两个节点，其中一个使用的是centos7.9版本的，启动成功，但是使用centos7.2的就启动失败。删除软件重新安装也不好使。
2、排查与调试
使用debug调试
# /usr/sbin/glusterd -f /etc/glusterfs/glusterd.vol -p /var/run/glusterd.pid --log-level DEBUG --log-file /var/log/gluster.log
通过从日志当中检索到如下异常：

3、解决
# yum -y install openssl-devel
借鉴：
