适用场景

  • FAS 存储节点(AFF 节点不受影响)
  • ONTAP 9.8或9.9.1
  • 在同一节点上具有本地层和云层的本地FabricPool 配置
  • 一个节点托管本地层的HA对和托管云层的HA配对节点、在接管时受影响

问题描述

  • 分层策略不会 none 分配给卷、而分层到云层处于活动状态。
  • 节点意外重新启动并显示崩溃消息:
Host memory checksum mismatch on WRITE VERIFY: Disk <disk_ID>, Disk Block #XXXX: Volume <Volume_name>, FileId XXX,File Block #XXX: Expected 0xYYYYYYYY, Recomputed as 0xZZZZZZZZ in SK process disk_server_0 on release 9.X (C)
  • 如果接管会将云层和性能层置于一个节点、则接管可能会导致崩溃。
  • 配对节点发出HA接管后、可能会发生相同的意外重新启动、从而导致HA对中断。
  • 如果HA对中的每个节点仅拥有本地层或云层、则只有在发出接管后才会触发崩溃。
  • 发生崩溃后的RAID擦洗揭示了奇偶校验错误、并引用了云层聚合:

  • 检测到不一致的用户数据块、请引用 <volume_name> 本地层聚合上的:

[node-01: wafl_exempt12: wafl.raid.incons.userdata:error]: WAFL inconsistent: inconsistent user data block at VBN XXX (vvbn:XXX fbn:XXX level:0) in public inode (fileid:XXX snapid:0 file_type:15 disk_flags:0x8402 error:120 raid_set:1) in volume <volume_name>@vserver:<Vserver_UUID>.
