Tag: para #, no-c-format msgid "STONITH is an acronym for Shoot-The-Other-Node-In-The-Head and it protects your data from being corrupted by rouge nodes or concurrent access." msgstr "STONITH 是爆其他节点的头（ Shoot-The-Other-Node-In-The-Head）的缩写，它能保护你的数据不被不正常的节点破坏或是并发写入。" #. Tag: para #, no-c-format msgid "Just because a node is unresponsive, this doesn’t mean it isn’t accessing your data. The only way to be 100% sure that your data is safe, is to use STONITH so we can be certain that the node is truly offline, before allowing the data to be accessed from another node." msgstr "因为如果一个节点没有相应，但并不代表它没有在操作你的数据，100%保证数据安全的做法就是在允许另外一个节点操作数据之前，使用STONITH来保证节点真的下线了。" #. Tag: para #, no-c-format msgid "STONITH also has a role to play in the event that a clustered service cannot be stopped. In this case, the cluster uses STONITH to force the whole node offline, thereby making it safe to start the service elsewhere." msgstr "STONITH另外一个用场是在当集群服务无法停止的时候。这个时候，集群可以用STONITH来强制使节点下线，从而可以安全的得在其他地方启动服务。" #. Tag: title #, no-c-format msgid "What STONITH Device Should You Use" msgstr "你该用什么样的STONITH设备。" #. Tag: para #, no-c-format msgid "It is crucial that the STONITH device can allow the cluster to differentiate between a node failure and a network one." msgstr "重要的一点是STONITH设备可以让集群区分节点故障和网络故障。" #. Tag: para #, no-c-format msgid "The biggest mistake people make in choosing a STONITH device is to use remote power switch (such as many onboard IMPI controllers) that shares power with the node it controls. In such cases, the cluster cannot be sure if the node is really offline, or active and suffering from a network fault." msgstr "人们常常犯得一个错误就是选择远程电源开关作为STONITH设备(比如许多主板自带的IPMI控制器) 。在那种情况下，集群不能分辨节点是真正的下线了，还是网络无法连通了。" #. Tag: para #, no-c-format msgid "Likewise, any device that relies on the machine being active (such as SSH-based “devices” used during testing) are inappropriate." msgstr "同样地， 任何依靠可用节点的设备（比如测试用的基于SSH的“设备”）都是不适当的。" #. Tag: title #, no-c-format msgid "Configuring STONITH" msgstr "配置STONITH" #. Tag: para #, no-c-format msgid "Find the correct driver: stonith -L" msgstr "找到正确的STONITH驱动: stonith -L" #. Tag: para #, no-c-format msgid "Since every device is different, the parameters needed to configure it will vary. To find out the parameters required by the device: stonith -t {type} -n" msgstr "因为设备的不同, 配置的参数也不一样。 想看设备所需设置的参数，可以用: stonith -t {type} -n" #. Tag: para #, no-c-format msgid "Hopefully the developers chose names that make sense, if not you can query for some additional information by finding an active cluster node and running:" msgstr "希望开发者选择了合适的名称，如果不是这样，你可以在活动的机器上面执行以下命令来获得更多信息。" #.

Tag: para #, no-c-format msgid "Create a clone from the primitive resource if the device can shoot more than one node and supports multiple simultaneous connections." msgstr "如果这个设备可以击杀多个设备并且支持从多个节点连接过来，那我们从这个原始资源创建一个克隆。" #.
