<div class="" style="word-wrap:break-word; line-break:after-white-space">So in my ongoing work to upgrade my cluster to CentOS 7, I got one box up and running on CentOS 7, with the cluster fully configured and functional, and moved all my services over to it.
Now I'm trying to add a second node, following the directions here:
<div class=""><br class="">
</div>
<div class=""><a href="https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/high_availability_add-on_reference/s1-clusternodemanage-haar#s2-nodeadd-HAAR" class="">https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/high_availability_add-on_reference/s1-clusternodemanage-haar#s2-nodeadd-HAAR</a></div>
<div class=""><br class="">
</div>
<div class="">However, it doesn't appear to be working. The existing node is named "follow3", and the new node I am trying to add is named "follow1":</div>
<div class=""><br class="">
</div>
<div class="">- The auth command run from follow3 returns "follow1: Authorized", so that looks good.</div>
<div class="">- The "pcs cluster node add follow1" command, again run on follow3, gives the following output:</div>
<div class=""><br class="">
</div>
<div class="">Disabling SBD service...<br class="">
follow1: sbd disabled<br class="">
Sending remote node configuration files to 'follow1'<br class="">
follow1: successful distribution of the file 'pacemaker_remote authkey'<br class="">
follow3: Corosync updated<br class="">
Setting up corosync...<br class="">
follow1: Succeeded<br class="">
Synchronizing pcsd certificates on nodes follow1...<br class="">
follow1: Success<br class="">
Restarting pcsd on the nodes in order to reload the certificates...<br class="">
follow1: Success<br class="">
<br class="">
...So it would appear that that worked as well. I then issued the "pcs cluster start --all" command, which gave the following output:</div>
<div class=""><br class="">
</div>
<div class="">[root@follow3 ~]# pcs cluster start --all<br class="">
follow3: Starting Cluster (corosync)...<br class="">
follow1: Starting Cluster (corosync)...<br class="">
follow3: Starting Cluster (pacemaker)...<br class="">
follow1: Starting Cluster (pacemaker)...</div>
<div class=""><br class="">
</div>
<div class="">So again, everything looks good (to me). However, when I run "pcs status" on the existing node, I get the following:</div>
<div class=""><br class="">
</div>
<div class="">[root@follow3 ~]# pcs status<br class="">
Cluster name: follow<br class="">
Stack: corosync<br class="">
Current DC: follow3 (version 1.1.19-8.el7_6.2-c3c624ea3d) - partition with quorum<br class="">
Last updated: Thu Jan 10 10:47:33 2019<br class="">
Last change: Wed Jan 9 21:39:37 2019 by root via cibadmin on follow3<br class="">
<br class="">
1 node configured<br class="">
29 resources configured<br class="">
<br class="">
Online: [ follow3 ]<br class="">
<br class="">
Full list of resources:<br class="">
<br class="">
which would seem to indicate that it doesn't know about the node I just added (follow1). Meanwhile, follow1 "pcs status" shows this:</div>
<div class=""><br class="">
</div>
<div class="">[root@follow1 ~]# pcs status<br class="">
Cluster name: follow<br class="">
Stack: corosync<br class="">
Current DC: follow1 (version 1.1.19-8.el7_6.2-c3c624ea3d) - partition WITHOUT quorum<br class="">
Last updated: Thu Jan 10 10:54:25 2019<br class="">
Last change: Thu Jan 10 10:54:13 2019 by root via cibadmin on follow1<br class="">
<br class="">
2 nodes configured<br class="">
0 resources configured<br class="">
<br class="">
Online: [ follow1 ]<br class="">
OFFLINE: [ follow3 ]<br class="">
<br class="">
No resources<br class="">
<br class="">
<br class="">
Daemon Status:<br class="">
corosync: active/disabled<br class="">
pacemaker: active/disabled<br class="">
pcsd: active/enabled<br class="">
</div>
<div class=""><br class="">
</div>
<div class="">So it got at least *some* of the config, but apparently not the full thing (no resources), and it shows follow3 as offline, even though it is online and reachable. Oddly "pcs cluster status" shows both follow1 and follow3 pcsd status as online.
What am I missing here?<br class="">
