问题描述

在意外重新启动单节点集群后、命令行界面会显示此消息：

***********************

** SYSTEM MESSAGES **

***********************

Internal error: Cannot open corrupt replicated database. Automatic recovery

attempt has failed or is disabled. Check the event logs for details. This node

is not fully operational. Contact support personnel for the root volume recovery

procedures.

报告有关vol0中用户数据块不一致的消息：

[Node-01: wafl_exempt01: wafl.raid.incons.userdata:error]: WAFL inconsistent: inconsistent user data block at VBN 11815817 (vvbn:46998 fbn:4125 level:0) in public inode (fileid:2326 snapid:0 file_type:1 disk_flags:0x2 error:117 raid_set:1) in volume vol0. [Node-01: wafl_exempt01: wafl.raid.incons.userdata:error]: WAFL inconsistent: inconsistent user data block at VBN 11815820 (vvbn:47001 fbn:4128 level:0) in public inode (fileid:2326 snapid:0 file_type:1 disk_flags:0x2 error:117 raid_set:1) in volume vol0.

尝试恢复节点的RDB后，节点以相同状态重新启动：
