D.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 host name. 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 host name.

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。

For example, the following entry in the configuration file always defines tag1, and defines tag2 if the host name is host1.

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

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