so why to use some other fencing method like disablink port on
switch, so nobody can acces faultly node and write data to it. it
is common practice too.<br class="">

<br>
Well don't get me wrong here. I don't want to hard-sell sbd.<br>
Just though that very likely requirements that prevent usage<br>
of a remote-controlled power-switch will make access<br>
to a switch to disable the ports unusable as well.<br>
And if a working qdevice setup is there already the gap between<br>
what he thought he would get from qdevice and what he actually<br>
had just matches exactly quorum-based-watchdog-fencing.<br>
<br>
But you are of course right.<br>
I don't really know the scenario.<br>
Maybe fabric fencing is the perfect match - good to mention it<br>
here as a possibility.<br>
<br>

Klaus<br>

cluster systems using the likes of iDRAC/IMM2
fencing agents, which have redundant but shared
power supply units with the nodes, the normal
fencing mechanisms should work for all resiliency
scenarios, but for IMM2/iDRAC are being NOT
reachable for whatsoever reasons. And, to bail out
of those situations in the absence of SBD, I believe
using used-defined failover hooks (via scripts) into
Pacemaker Alerts, with sudo permissions for
‘hacluster’, should help.</span></div>
