RecoverPoint:一致性组由于“SYM 找不到快照集”而进入错误状态

Summary: RecoverPoint:一致性组由于 [SYM 未能找到快照集] 而进入错误状态

Symptoms

由于 [SYM 找不到快照集]迫使整个组进入已启用且无传输状态,CG 的链接陷入错误。

Error: 组cg_name的一个或多个链路设置为复制快照,并且在基于快照的复制过程中发生错误。从存储收到以下错误:

Link = cg_name->cg_name_copy, error = [SYM failed to find snapset]

在日志中发现的症状:

Cause

由于 XtremIO 与 XMS 之间的不一致,RecoverPoint 在检索必须丢弃的快照的当前列表时从 XMS 接收以前的条目。

偶尔会收到意外值,并且将用于删除的快照用作当前快照,而不是必须丢弃的上一个快照。这会导致删除实际快照。

因此,对于与已删除的快照关联的组,来自阵列的调用开始失败,这会导致拷贝的链接进入错误状态 [SYM 找不到快照集],由于组的链路关闭,整个 CG 将进入已启用的错误状态,且无传输。

 

Resolution

解决办法:

  1. 禁用 CG,然后重新启用 CG
  2. 将所有生产 RPA 上的调整t_xioPeriodicalSnapCleanupGatherInterval从 600000 更改为 600000000 (x1000)。此更改会导致清理工具每周运行一次,而不是每 10 分钟运行一次,从而降低遇到问题的可能性。

分辨率:
此问题的修复程序在 XtremIO 4.0.27-1、XMS 6.2.1-36 中可用。

 

Additional Information

受影响的配置:
具有 XtremIO 阵列的 RecoverPoint Classic(XtremIO 4.0.27-1、XMS 6.2.1-36 之前)
