Hi,
I create cluster contain three nodes when I remove one of the node by
run "pcs cluster destroy" command
This is the root cause of your problem. "pcs cluster destroy" only
wipes out cluster configuration from a node but it does not tell the
rest of the cluster that the node got removed. Use "pcs cluster node
remove" to remove a node from a cluster.
The node was stopped from cluster, but when I try to rejoin the node
by run commands
1-systemctl start pcsd.service
2-systemctl start pcsd.service
(one removed node)
3-*pcs cluster auth*
4-*pcs cluster node add*
(On a node in the existing cluster)
the output from last command (Error: unable to add hosname1 on
hostname2- Error connecting to hostname2- (HTTP error: 400
Error: unable to add hostname1 on hostname3 - Error connecting to
hostname3 - (HTTP error: 400)
Error: unable to add hostname1 on hostname1- Error connecting to
hostname2 - (HTTP error: 400)
Error: Unable to update any nodes
This fails most probably because the node you want to add is still
present in the cluster configuration on the remaining nodes. You can
get detailed info by running "pcs cluster node add --debug".
Now to fix that run "pcs cluster localnode remove " on the
two remaining nodes. Then you can add the removed node back to the cluster.

Any idea what is the problem ?
Thanks
