适用场景

问题描述

  • SnapMirror 初始化 / 更新 / 重新同步过去显示类似的错误

Transfer for volume "volume_name" failed. Reason: Transfer failed. (Volume access error (I2P corruption detected))

  • 在 SnapMirror 传输的源卷上, NDMP 备份或基于 NDMP 的快照处于活动状态 / 存在状态
  • 在卷传输过程中进行 SnapMirror 传输时,未执行卷重命名
  • SnapMirror 目标节点将使用类似于以下内容的崩溃字符串重新启动:

panic:page fault (supervisor read data, page not present) on VA 0x34 cs:rip 0x20:0xffffffff8f814854 rflags 0x10246 in SK process wafl_exempt04 on release <ONTAP version without fix>

  • 最终,在配对节点因初始崩溃而接管服务后,配对节点也可能发生崩溃,从而导致服务中断
