Comment on openais: an alternative to clvm with cman by Dave

I’ve now also had success using clvm directly with corosync on Squeeze by compiling clvm by changing –with-clvmd=cman to –with-clvmd=corosync.

The above patch to /etc/init.d/corosync is still needed if you plan to layer o2cb (OCFS2) on your cLVM as o2cb depends upon openais services.

Sorry JCL – I really should create my own blog ;)

To help Googlers find this page, the output you would receive when starting clvmd -d without the above patch would be similar to this:

root@xen5.tst:/etc/corosync# clvmd -d
CLVMD[7276f7a0]: Jul 5 16:27:12 CLVMD started
CLVMD[7276f7a0]: Jul 5 16:27:12 Cannot initialise OpenAIS lock service: 12

CLVMD[7276f7a0]: Jul 5 16:27:12 Can’t initialise cluster interface

Thanks for the kind words ;)

I hit another issue with using a patched clvm on Debian Squeeze today which I have resolved using the following patch to /etc/init.d/corosync (thanks to Michael Schwartzkopff who has alerted the Debian corosync maintainer). As of corosync-1.2.1-4 this is not yet patched in the Debian package. I have provided the required change as a unified diff here for people who follow the above and hit this issue. In addition to this patch please add

OPENAIS_SERVICES=yes

to your /etc/default/corosync.
