问题描述

聚合在 failed AWS Cloud Volumes ONTAP 环境中显示：

Your_AWS_node::> aggr show

Aggregate Size Available Used% State #Vols Nodes RAID Status --------- -------- --------- ----- ------- ------ ---------------- ------------ aggr0_Your_AWS_node_01 124.0GB 6.01GB 95% online 1 Your_AWS_node-01 raid0, normal aggr1 0B 0B 0% failed 0 Your_AWS_node-01 raid0, partial 2 entries were displayed.

在 EMS 中会显示以下消息：

12/9/2021 15:48:15  Your_AWS_node-01 ALERT      sk.panic: Panic String: aggr aggr1: raid volfsm, fatal disk error in RAID group with no parity disk..

disk show 输出不会按预期列出构成聚合的所有磁盘。在此示例中， aggr1 只能看到 5 个磁盘，但我们从先前的 AutoSupport 中知道聚合中应有 6 个磁盘：

Your_AWS_node::> disk show Usable Disk Container Container Disk Size Shelf Bay Type Type Name Owner ---------------- ---------- ----- --- ------- ----------- --------- -------- NET-1.1 137.8GB - - VMDISK aggregate aggr0_Your_AWS_node_01 Your_AWS_node-01 NET-1.3 1007GB - - VMDISK aggregate aggr1 Your_AWS_node-01 NET-1.4 1007GB - - VMDISK aggregate aggr1 Your_AWS_node-01 NET-1.5 1007GB - - VMDISK aggregate aggr1 Your_AWS_node-01 NET-1.7 1007GB - - VMDISK aggregate aggr1 Your_AWS_node-01 NET-1.8 1007GB - - VMDISK aggregate aggr1 Your_AWS_node-01 6 entries were displayed.

在此示例disk show 中，我们可以看到，在将当前输出与先前的 AutoSupport 进行比较时，磁盘 NET-1.6 丢失。
