标题: 请教一个分布式锁的问题（DLM）
我要单独测试一下这个分布式锁（DLM），但是按照dlm源码中的说明搭建不起来这个环境。
有谁搞过这个，帮偶解释一下，不胜感激~

附上一段测试说明：

The dlm is configured and controlled from user space through sysfs and a
couple of ioctl's.  A command line program, dlm_tool, can be used to do
everything manually.

Here are the dlm_tool config/control actions that will be used:

set_local  <nodeid> <ipaddr> [<weight>]
set_node <nodeid> <ipaddr> [<weight>]
stop    <ls_name>
terminate  <ls_name>
start    <ls_name> <event_nr> <type> <nodeid>...
get_done <ls_name>
finish    <ls_name> <event_nr>
set_id    <ls_name> <id>

For testing and illustration, some actions have been added to dlm_tool to use
the libdlm API.

create    <ls_name>
release <ls_name>
lock    <ls_name> <res_name> <mode> [<flag>,...]
unlock    <ls_name> <lkid>          [<flag>,...]
convert <ls_name> <lkid> <mode>    [<flag>,...]

So, dlm_tool is standing in for what would usually be two different entities.
The first set of config/control actions would usually be performed by a system
daemon associated with a cluster membership manager.  The second set of libdlm
actions would usually be performed by an application that wants to use the dlm
for synchronization.
