NostawRmgot a thought that I don't know if its plausible or if its just a bad idea. When killing a node to ensure its down, I know the primary option is to shut it down via IPMI, but is there anything blatantly wrong/bad with just killing the dedicated storage network port at the switch?12:40
NostawRmI don't see the downsides to this, especially if I can find how to make pacemaker do it because then we can very safely trouble shoot the node and know what went wonky12:41

NostawRmfound an argument against it, switchport fencing would be shutdown only, no reboot, so even though we'd see what was on the terminal at lock up, that resource would be down until we got to it12:52

aspiersNostawRm: resource fencing can be as effective as node fencing in some circumstances. It's a well-known technique13:56
aspiersdepends on what resources the node was managing13:56
aspierss/-known/-established/13:57
NostawRmwell, that's where I'm leaning away from it now. At least to start off, our cluster is hyper converged ceph/openstack, so if a node was to hang, then not only is that hypervisor gone, but so is 3-4 OSDs13:57
NostawRmthink everyone else who would have hands on it would prefer being able to look at the console to see what's up before the node tried to reboot, but getting those OSDs back is going to be a big deal, especially early on13:58
