C.2. 主​​​​​​​机​​​​​​​标​​​​​​​签​​​​​​​

In a cluster configuration, you can define host tags in the configuration files. If you set hosttags = 1 in the tags section, a host tag is automatically defined using the machine's hostname. This allow you to use a common configuration file which can be replicated on all your machines so they hold identical copies of the file, but the behavior can differ between machines according to the hostname.

For information on the configuration files, see 附录 B, LVM 配​​​​​​​置​​​​​​​文​​​​​​​件​​​​​​​.

对​​​​​​​于​​​​​​​每​​​​​​​个​​​​​​​主​​​​​​​机​​​​​​​标​​​​​​​签​​​​​​​，如​​​​​​​果​​​​​​​存​​​​​​​在​​​​​​​额​​​​​​​外​​​​​​​的​​​​​​​配​​​​​​​置​​​​​​​文​​​​​​​件​​​​​​​ lvm_hosttag.conf，就​​​​​​​会​​​​​​​读​​​​​​​取​​​​​​​它​​​​​​​。​​​​​​​如​​​​​​​果​​​​​​​那​​​​​​​个​​​​​​​文​​​​​​​件​​​​​​​定​​​​​​​义​​​​​​​了​​​​​​​新​​​​​​​的​​​​​​​标​​​​​​​签​​​​​​​，那​​​​​​​么​​​​​​​会​​​​​​​在​​​​​​​要​​​​​​​读​​​​​​​取​​​​​​​的​​​​​​​文​​​​​​​件​​​​​​​列​​​​​​​表​​​​​​​中​​​​​​​添​​​​​​​加​​​​​​​进​​​​​​​一​​​​​​​步​​​​​​​的​​​​​​​配​​​​​​​置​​​​​​​文​​​​​​​件​​​​​​​。​​​​​​​

例​​​​​​​如​​​​​​​：下​​​​​​​面​​​​​​​配​​​​​​​置​​​​​​​文​​​​​​​件​​​​​​​中​​​​​​​的​​​​​​​条​​​​​​​目​​​​​​​总​​​​​​​是​​​​​​​定​​​​​​​义​​​​​​​ tag1，且​​​​​​​在​​​​​​​主​​​​​​​机​​​​​​​名​​​​​​​为​​​​​​​ host1 定​​​​​​​义​​​​​​​ tag2。​​​​​​​

tags { tag1 { }  tag2 { host_list = ["host1"] } }
