[Muhammad Alim]

Hello, i got this error when i tried to re joining the nodes into a cluster.

Starting cman... corosync died: Could not read cluster configuration Check cluster logs for details
How do I fix this ?

Well what do the logs say? heck, you even put it in bold. How many nodes in the cluster? How long have you had the cluster running? is this the first time you have tried to rejoin the cluster with this node? how did the node leave the cluster?

AKA, provide more info so we can help!

I have 4 nodes connected, actually this node is part of them, so in total there are 5 nodes.
but suddenly this one is separated from the cluster. So i want to re-join this node. but I got that following error.

p.s i don't know how can this node leave the cluster...

I guess checking the cluster logs for details... is a good start to sort out how to fix it.
