错误的主块“/dev/chunk1317”？

Question

通过 os 级别克隆将 informix 二进制文件迁移到新服务器后，当我执行 oninit -vy 时出现警告，如无法打开某些块。然后我询问系统管理员 link those 丢失的块并再次执行 oninit -vy 它提示警告并提及 those 块是坏块。这背后的原因是什么？ chunks重新配置到新服务器时有没有错误发生

这是第 os 个块的 onstat -d 输出

Answer 1

我可以通过以下命令打开这些块来解决上述错误。

onspaces -s  [dbspace_name] -p [pathname] -o [offset] -O

例如：-

onspaces -s  dbspace1 -p /dev/chunk1186 -o 96 -O

错误的主块“/dev/chunk1317”？

Bad Primary Chunk '/dev/chunk1317'?
