数据迁移的问题

[moziie]

服务器宕机硬盘坏了只拷贝出来/var/lib/taos文件夹中所有内容，数据都在这个路径中，请问换了新硬盘，重新搭建了Tdengine如何将这部分数据复制进去

[sangshuduo]

hostname 和 taos.cfg 里的 firstEp 和之前的保持一致应该就可以访问之前的数据。如果 locale timezone 也改过，也请保持一致。

[moziie]

hostname 和 taos.cfg 里的 firstEp没有变化，locale timezone也没有改过，具体操作就是将之前的/var/lib/taos路径下所有东西覆盖掉当前/var/lib/taos路径下所有东西，然后连接查询就可以么

[sangshuduo]

对，应该就可以。你可以先不用 systemctl start 方式启动，直接用命令行起 taosd ，这样看输出方便一些，然后用另外的 terminal 里起 taos 连taosd，如果可以连接把手动起的 taosd ctrl-c 停掉再用 systemctl 起就可以了

[moziie]

好的谢谢，但是我已经使用systemctl start 方式启动过，我先覆盖试一下，有问题再来咨询您

命令行taosd打印这些之后就没启动成功，然后就连接不上

[sangshuduo]

后面有 core dump，有生成 core 文件吗？如果有 core 文件，用 sudo gdb taosd core ，然后 bt 命令看一下 call stack 失败在哪里

[moziie]

find命令，没有找到core文件

[sangshuduo]

可以 enable coredump 再跑一下吗？http://senlinzhan.github.io/2017/12/31/coredump/
