ceph集群警告和错误类型

noscrub flag(s) set

防止集群做清洗操作

full flag(s) set

使集群到达设置的full_ratio值。会导致集群阻止写入操作

nodeep-scrub flag(s) set

防止集群进行深度清洗操作

pause flag(s) set

noup flag(s) set

防止osd进入up状态

nodown flag(s) set

防止osd进入down状态

noout flag(s) set

防止osd进入out状态

nobackfill flag(s) set

防止集群进行数据回填操作

norebalance flag(s) set

防止数据均衡操作

norecover flag(s) set

避免关闭OSD的过程中发生数据迁移
