hi guys,
I have a 3-node cluser(centos 7.5), 2 nodes seems fine but
third(or probably something else in between) is not right.
I see this:
$ pcs status --all
Cluster name: CC
Stack: corosync
Current DC: whale.private (version
1.1.18-11.el7_5.3-2b07d5c5a9) - partition with quorum
Last updated: Fri Oct 12 15:40:39 2018
Last change: Fri Oct 12 15:14:57 2018 by root via
crm_resource on whale.private
3 nodes configured
8 resources configured (1 DISABLED)
Online: [ rental.private whale.private ]
OFFLINE: [ rider.private ]
and that third node logs:
[TOTEM ] FAILED TO RECEIVE
[TOTEM ] A new membership (10.5.6.100:2504344) was formed.
Members left: 2 4
[TOTEM ] Failed to receive the leave message. failed: 2 4
[QUORUM] Members[1]: 1
[MAIN ] Completed service synchronization, ready to
provide service.
[TOTEM ] A new membership (10.5.6.49:2504348) was formed.
Members joined: 2 4
[TOTEM ] FAILED TO RECEIVE
and it just keeps going like that.
Sometimes reboot(or stop of services + wait + start) of that
third node would help.
But, I get this situation almost every time a node gets
(orderly) shut down or reboot.
Network-wise, connectivity, seem okey. Where to start?
many thanks, L
