Hi!

I got 3 normal pc server without any remote management like no HP ILO or something. So no fencing / stonith support now.
For 2 server or for 3 server it's needed to be?

If I get an Ethernet network relay - what can turn on/off servers, it's recommended to get it? Like if need to stonith 2. server, server 1 can access with IP address the Ethernet network relay, and can power off the 2. server or itself too.

Please help.

STONITH is good to have, but not mandatory.

A 2 node pool will work without it. You can alternatively call a script to control a PDU that can turn off the server.

Thank you. If I have 3 node, but 3. all times disabled or enabled for sync?

If I got 3 node, and I enable the 3. node for few hour weekly (to be full sync), it can be a proper backup, right?
If the 1. or 2. node down, I enable 3. node and it will works fine after sync?
