90 天分级无法按预期运行
适用于
- ONTAP 9
- FabricPool
问题
- 卷未将冷数据分层到云层。
- 分级策略设置为自动，最小冷却天数设置为 90。
- 聚合已达到默认分层满度阈值（默认情况下为 50%）和容量阈值。
- 从
"volume show-footprint"我们确实看到一些数据是分层的。

- EMS 日志表明正在进行分层：
[Node-01: scan_ca_tiering_wkr: wafl.scan.start:debug]: Starting composite aggregate tiering on volume volume1@vserver:xxxx.
[Node-01: wafl_scan_exempt: wafl.scan.done:notice]: Completed composite aggregate tiering on volume volume1@vserver:xxxx.
- 命令
"object-store tiering show -instance"确认定期进行分层，没有报告错误。
