cephfs 在L版本已经比较稳定了,这个稳定的意义个人觉得是在其故障恢复方面的成熟,一个文件系统可恢复是其稳定必须具备的属性,本篇就是根据官网的文档来实践下这个恢复的过程 实践过程 部署一个ceph Luminous集群 [root@lab102 ~]# ceph -vceph version 12.2.5 (cad919881333ac92274171586c827e01f554a70a) luminous...
没有出现持续大量数据写入时产生的高内存占用问题,同时,重启其中一个rank,备用的mds会自动顶上,业务没有太大影响,而且,目录内的文件数只要不是太大,小于百万级的话,性能也没有太大的问题,因此,14.2.20及后续版本的cephfs应该是可以上生产的了

最近重新对cephfs进行性能测试。 测试步骤: (1) 选取一个特地版本的操作系统内核,挂载20000个客户端; (2) 用iozone中的fileop工具,在每隔挂载点上都跑一个fileop进程; (3)过一段时间看写cephfs的状态,结果就变成下面这样的了。 [root@ceph741 ~]# ceph -scluster 1338affa-2d3d-416e-9251-4aa6e9c20ee...
