13.2. Ce Dispozitiv STONITH Ar Trebui Să Folosiţi

It is crucial that the STONITH device can allow the cluster to differentiate between a node failure and a network one.
The biggest mistake people make in choosing a STONITH device is to use remote power switch (such as many on-board 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.
În mod similar, orice dispozitiv care se bazează pe maşină să fie activă (cum ar fi "dispozitivele" bazate pe SSH folosite în timpul testării) sunt nepotrivite.
