further from this last year, I am in the process of doing some rhels6.5 installs, and again RedHat have changed it again.
Now they officially support pcs. But there are docs suggesting that they will be moving away from corosync, and therefore need to use ccs and cman. I have spent a couple of days on this, and have now updated the (the below mentioned) documentation a bit, and added a Appendix B, with the relevant configs for cman, and the config changes for pcs. FYI, I have successfully done HA with pcs already with at least 3 customer sites(rhel6.4), and one with crm (rhel6.3) The customer even installed the Primary MN with the secondary, and it was successful. So thanks again for the xCAT team for all the original docs. regards, Arif -- Arif Ali IRC: arif-ali at freenode LinkedIn: http://uk.linkedin.com/in/arifali On 21 August 2013 02:29, Guang Cheng Li <[email protected]> wrote: > HI Arif, > > Thanks for the configuration listed below, I updated the xCAT doc > *http://sourceforge.net/apps/mediawiki/xcat/index.php?title=Setup_HA_Mgmt_Node_With_DRBD_Pacemaker_Corosync*<http://sourceforge.net/apps/mediawiki/xcat/index.php?title=Setup_HA_Mgmt_Node_With_DRBD_Pacemaker_Corosync> > to > reflect this.
