If you're already happy with and currently using Pacemaker for this purpose, then by all means carry on. Keepalived is lighter weight, but probably not so much that you'll notice. I tend to use Pacemaker when I need to make several things fail over together and Keepalived when I just need to float an IP between a few machines. It's just personal preference really. > ________________________________ > From: Erik McCormick <emccorm...@cirrusseven.com> > Sent: 3/19/18 10:27 AM > To: torin.wolt...@granddial.com, openstack-operators > <openstack-operat...@lists.openstack.org> > Subject: Re: [Openstack] HA Guide, no Ubuntu instructions for HA Identity > Looping the list back in since I accidentally dropped it yet again :/ > > On Mon, Mar 19, 2018 at 8:45 AM, Torin Woltjer > wrote: >> That's good to know, thank you.
