事件日志中会显示类似于以下内容的错误消息:

系统会针对磁盘报告 checkCondition 错误:

在同一秒内报告了不一致的情况:

每当触发上述错误时,擦洗始终会发现 64 个写入签名不一致,并触发 "DISK Scrub parity inconsistency" AutoSupport :
Mon Jan 18 02:39:18 +0300 [Node1: config_thread: raid.rg.scrub.summary.lw:notice]: Scrub found 64 RAID write signature inconsistencies in /aggr0_Node1/plex4/rg0.
