Dear Honza,
Sorry for late reply.
After I have tested with all new configuration.
On IPv6 only, and with no altname.
I face with error below,
Starting cluster:
Checking if cluster has been disabled at boot... [ OK ]
Checking Network Manager... [ OK ]
Global setup... [ OK ]
Loading kernel modules... [ OK ]
Mounting configfs... [ OK ]
Starting cman... corosync died with signal: 6 Check cluster logs for details
[FAILED]
And, exactly, there are no any enabled firewall, I also configure the
Multicast address as manual.
Could you advise me the solution?
Many thanks in advance.
Te
