The most efficient way of getting corosync facts about nodes/quorum is to use the votequorum API. see /usr/include/corosync/votequorum.h and in the corosync sources tarball tests/testvotequorum1.c CHrissie On 25/02/2021 07:16, Ulrich Windl wrote: Hi! I'm thinking about some simple cluster

[ClusterLabs] Q: effieciently collecting some cluster facts

2021-02-24 Thread Ulrich Windl
Hi! I'm thinking about some simple cluster status display that is updated periodically. I wonder how to get some "cluster facts" efficiently. Among those are: * Is corosync running, and how many nodes can be seen? * Is Pacemaker running, how many nodes does it see, and does it have a quorum? *
