Howdy! Thanks for the responses. Surprisingly, clvmd does work as-is in 11.1, as long as you have openais and pacemaker installed and running already. However, it does not (obviously) show up as a resource controlled by pacemaker in crm_mon; "0 resources configured." ocfs2 also works, but has to be started manually on reboot because obviously clvmd isn't running yet ... (see below)
I'm a newbie to pacemaker configuration, so I haven't yet figured out how to get clvmd set up as a service with pacemaker. I have it started manually right now. This obviously isn't proper, and some RTFM would definitely solve the issue, but I'd like to go home at some point tonight... Queries, some of which are ocfs2-specific and you can skip them if you can't answer: 1) Where are the dummy examples for adding clvmd to pacemaker? 2) What other pieces do I need to add to /etc/init.d/ and set to start? 3) Right now, after starting clvmd I need to run pvscan and lvscan before I can see the lvm2 volume, whereupon I can start ocfs2 and mount the volume. How do I automate this process, or will pacemaker do it for me once I have it configured properly? 4) I'm using the standard o2cb cluster stack; do I need to change this for pacemaker? (again, obviously it's working, but...) 5) Fencing. Does ocfs2 handle the fencing, or do I need to find and install a fencing manager that I haven't found so far? I sincerely apologize for the newbie questions, and I promise that "I'm blogging this" and once I've got it working and repeatable, it'll be googleable. -K >>> Lars Marowsky-Bree <l...@suse.de> 4/24/2009 6:24 AM >>> On 2009-04-23T18:44:35, Karl Katzke <kkat...@tamu.edu> wrote: > > Howdy! > > I'm attempting to get CLVM set up on OpenSuSE 11.1 with pacemaker and openais. So far I *seem* to have most things installed, but I'm having difficulty getting the lvm groups to talk. I don't think cLVM in 11.1 works as-is. Which packages did you install? We fixed it in SLE11 HA, but that was post-11.1; though Factory should have all the code, so should the openSUSE build service. > Before I start reinventing the wheel and asking a whole load of stupid > questions, has anyone produced a howto on getting clvmd set up with > lvm2?

It is quite simple; change the locking type in lvm.conf to 3, add the ocf:pacemaker:controld and ocf:lvm2:clvmd resources as clones to the configuration, and then vgcreate -c etc will simply start working. It's also documented in the SLE11 HA docs; they are LGPL, but due to the release pressure, we've not yet sync'ed the latest copy to the outside I think.
