双网卡机器部署storage会让tracker多发现几个storage的问题求助。

Question

我用的机器2个网卡，对应不同ip，每个机器的storage只配置监听1个ip，一共是3个group分别对应端口23000、23002、23003，每个group有2个storage，192.168.3.167跟192.168.3.27同一台机器，192.168.3.168跟192.168.3.28同一台机器，只监听192.168.3.167和192.168.3.168的

结果从monitor工具看到4个group：
$ ./fdfs_monitor ../conf/storage.conf
group count: 4

Group 1:
group name = group1
free space = 66 GB
storage server count = 3
active server count = 2
storage_port = 23000
store path count = 1
subdir count per path= 256
current write server index = 0

如何避免这种情况出现呢？

Answer 1

tracker server是根据对端IP来获取storage server的IP地址的。
对于你说的情况，因为一台机器的两个IP都是同一个网段的，所以tracker server获取到的storage server的IP地址很可能是不确定的：有时获取到的是IP1，有时获取到的是IP2。
建议只使用一块网卡，或者将另一个网卡的IP地址设置为其他网段。
