判断ceph osd 节点磁盘异常

1 执行 ceph orch device ls --refresh

--refresh 是异步刷新，等待五分钟，再执行一次，没有刷新的磁盘是异常的。比如 ceph01 上的两个磁盘没有按时刷新。

复制代码

[ceph: root@ceph03 /]# ceph orch device ls --refresh

2 执行 ceph-volume inventory

ceph-volume inventory 是用来获取当前节点所有可用磁盘清单的命令，会显示当前节点异常的磁盘。

复制代码

[ceph: root@ceph03 /]# ceph-volume inventory

查看/var/log/ceph/ceph-fid/ceph-volume.log 日志
ceph-volume.log 日志里面记录磁盘层面的日志。
