Ok, so my assumption fits in this case, in the context of node1. And only now I can see the source of this overall confusion, glad you've tracked that down. >> 2. why shall a single malfunctioned node (out of three) irrefutably >> result in dismounting of otherwise healthy cluster? >> (if that's indeed what you presume) > > I don't presume that. That was my slightly obtuse attempt to unfold the seemingly incomplete or downright confusing picture (subject to interpreting "however" in the original report). Sorry for that, luckily, you seem to have all the answers by now. As for systemd, you can also use "systemctl is-active <unit>", and within pcs context, "pcs status" will also serve a "Daemon Status" at the bottom of its output, where also corosync should be detailed unambiguously. -- Jan (Poki)
