磁盘主动式刷新启动和结束错误
适用场景
- ONTAP 9
- FAS
- AFF
问题描述
- 磁盘上存在严重的转储错误和延迟错误：
node03-nfsxxx.mail.bf1.inc.com [node03-nfshs101-mail-bf1:disk.timeout.flush.start:debug]: Aggressive timeout flush started on disk 3a.07.22L1.
node03-nfsxxx.mail.bf1.inc.com [node03-nfshs101-mail-bf1: disk.timeout.flush.end:debug]: Aggressive timeout flush ended on disk 3a.07.22L1.
- ONTAP 将在运行更正算法后使磁盘出现故障、并显示以下错误：
node03-nfsxxx-mail-bf1: disk_latency_monitor: shm.threshold.highIOLatency:error]: Disk 3b.02.14L1 exceeds the average IO latency threshold and will be recommended for failure.
