在 SnapMirror 或 SnapVault 集群中发生 raid_multierr_bad_block_1 错误后复制了 wafl.raid.incons.userdata 消息

适用场景

• ONTAP
• 具有 SapMirror 和 / 或 SnapVault 目标集群的生产集群
• 复制的块存在用户数据不一致

问题描述

• SnapMirror 和 SnapVault 目标节点中具有相同文件块编号（FBN）和 文件 ID的 WAFL 用户数据不一致块消息。示例：

Fri Sep 17 06:23:59 CEST [SnapMirror_node1: wafl_exempt02: wafl.raid.incons.userdata:error]: WAFL inconsistent: inconsistent user data block at VBN 1792908851 (vvbn:10473883 fbn:22189 level:0) in public inode (fileid:12103 snapid:0 file_type:1 disk_flags:0x8002 error:120 raid_set:0) in volume mirror_volume@vserver:mmmmmmmm-mmmm-mmmm-mmmm-mmmmmmmmmmmm.

Fri Sep 17 08:22:04 CEST [SnapVault_node1: wafl_exempt00: wafl.raid.incons.userdata:error]: WAFL inconsistent: inconsistent user data block at VBN 3028359178 (vvbn:5407137 fbn:22189 level:0) in public inode (fileid:12103 snapid:0 file_type:1 disk_flags:0x8002 error:120 raid_set:0) in volume vault_volume@vserver:vvvvvvvv-vvvv-vvvv-vvvv-vvvvvvvvvvvv.

• 同一 FBN 和文件 ID 的源 / 生产节点中存在不一致：

Sat Sep 18 00:10:06 CEST [Production_node1: wafl_exempt01: wafl.raid.incons.userdata:error]: WAFL inconsistent: inconsistent user data block at VBN 13045486183 (vvbn:11602768 fbn:22189 level:0) in public inode (fileid:12103 snapid:0 file_type:1 disk_flags:0x2 error:120 raid_set:1) in volume production_volume@vserver:pppppppp-pppp-pppp-pppp-pppppppppppp.

• 先前该虚拟块编号（VBN）的错误 RAID 多错误块：
