1.x的安装目录：/usr/local/nebula_v1
2.6的安装目录: /usr/local/nebula_v2
先执行1.x到2.6的etc配置覆盖，并启动2.6的metad，nebula-metad.ERROR显示如下：
Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
E0726 14:51:22.330767 30882 FileUtils.cpp:370] Failed to read the directory “data/meta/nebula” (2): No such file or directory
E0726 15:12:01.085906 30994 ActiveHostsMan.cpp:247] Get last update time failed, error: E_KEY_NOT_FOUND
- 查看metad进程启动正常 ps -ef|grep nebula-mated
- 在2.6的目录下执行 ：mkdir -p data/storage
- 在2.6的bin目录下执行：./db_upgrader --src_db_path=/usr/local/nebula_v1/data/storage --dst_db_path=/usr/local/nebula_v2/data/storage/ --upgrade_meta_server=127.0.0.1:45500 --upgrade_version=1

请问出现上面异常时什么原因呢？
