Well, no, not really. Some of the resources should've been configured. Most importantly, the one I already mentioned; DLM. Sure, you can have everything outside of pacemaker, but what's the point of pacemaker then? By just recompiling lvm to support openais, you still need DLM which supports pacemaker. For that, in Lucid, you have to recompile RedHat Cluster Suite, which is the source of DLM, and enable support for pacemaker in it. Of course, you could just use ubuntu-ha PPA and then you wouldn't have to compile anything by your self. Once you have those packages in place, you must start dlm_controld.pcmk, which brings DLM to pacemaker and then start clmvd on top of it. In case you don't want/have DLM, you have to look into the old and abandoned EVMS (unsupported everywhere). Your setup can't work anywhere. You need DLM. -- You received this bug notification because you are a member of Ubuntu High Availability Team, which is a direct subscriber. https://bugs.launchpad.net/bugs/719333 Title: CLVM not locking LV's properly even when set to "exclusive" Status in lvm2 - Logical Volume Manager: Unknown Status in “lvm2” package in Ubuntu: Invalid Bug description: Binary package hint: lvm2 Hello, i got Ubuntu Lucid Server + openais + lvm + clvm running on a central storage.
