Hello everyone!
I would like to ask a few questions about the main road of the cluster
stack evolution.
1) The RedHat company is planning to drop corosync support and wants to
switch to CMAN. (
http://www.gossamer-threads.com/lists/linuxha/pacemaker/84662 )
What do you think the main trend is? What is the most popular and better
supported solution? Corosync, CMAN or something else?
What cluster engine is better for Pacemaker at the moment? And what
could be the best solution in 2-3 years?
2) What is the best tool for cluster management: crm, pcs or something
else?
Redhat switches to pcs and drops crm, but SUSE prefers crmsh tool.
Why? What tool will you advice to use?
3) What version of pacemaker should I prefer for using on RedHat 6.3 (or
6.4) ?
The version from the vendor (Pacemaker 1.1.7 for RedHat 6.3 and
Pacemaker 1.1.8 for RedHat 6.4) or the upstream version from Github?
I usually prefer software versions coming from the distribution, because
I hope they are well-tested and supported by the vendor.
But, as I know, Pacemaker is a teсhnology preview in RedHat 6, so they
don't response for it stability.
Also, all the same, I have to rebuild Redhat src.rpm package ( for
adding corosync 2.3 support into pacemaker)
With best regards,
Ivan Khalezov
