Not sure, but did you use YaST to configure the target? The file
you mention above is auto-generated.

It is arguably good practice that nodes don't join cluster
automatically on boot. Normally, one wants to investigate why
the node rebooted.

This is certainly an open-iscsi or distribution issue.

Thanks,

Mmmm.... this thinking is along the same lines of Microsoft's forcing you to enter a reason every time you reboot, regardless of whether anyone cares or not. Also, if that's intentional, then the openais service should still start, but not automatically join the cluster - as it is, it just fails on SBD which is clearly not desired behavior. And if the intent is to not be incredibly irritating, this should only happen on a 'dirty' reboot.

But point taken, the problem really has nothing to do with openais per se, it has to do with open-iscsi. I'll see if I can figure out where that product hosts its support lists...

Thanks!
