Corosync error and ha detection error after removing 1 node in cluster.

[DuyQuy]

Hi all.

I have previously removed 1 node from the cluster, but recently we noticed that HA is giving an error (unable to read lrm status)



When I switched to check corosync, I noticed that they misdetected its own node ID information. For example. node ID:04 but its corosync is receiving ID:11 resulting in ID:04 disconnected.



This wrong detection of localhost information only happens on some nodes, I think that is the cause of HA failure. Is there any way to deal with that?

please update to the latest 6.4 and then 7.x - 6.4 is EOL, and your versions of corosync and kronosnet (the software underpinning our cluster stack) are outdated versions with known bugs.
