I am using pacemaker, corosync and ocfs2 on Fedora 12 to build an
active/active cluster. When I try to start up o2cb resource with
ocfs2-tools-pcmk-1.4.3-3.fc12.x86_64 that comes with Fedora 12 it
produces
the following errors:
Dec 30 22:06:29 ilo150 corosync[3866]: [pcmk ] info: pcmk_notify:

Does anyone know if this is a problem on the ocfs2 side or corosync
side?
- Have you installed openais package?
- ocfs2_controld is using the CKPT service which is provided by openais
- not corosync.
really? I did not know that. So my best bet is either switch to openais
or
You might misunderstand what I said. It is not "switch to openais" but
"install
the openais as well". That is to say, both corosync and openais package
are needed :)
I am getting a little confused now and maybe I missed some information here.
On the other cluster where openais is in use I had to set the cluster
communication - authkey, totem and interface etc. With this one I am working
on I did pretty much the same in corosync. Now you are saying I need to turn
on openais to work with corosync but the question is where I should put
those settings? openais.conf, corosync.conf or both? and which package is
supposed to start up pacemaker processes which are done through corosync at
the moment:
1111 ? Ssl 0:10 corosync
1117 ? SLs 0:00 \_ /usr/lib64/heartbeat/stonithd
1118 ? S 0:03 \_ /usr/lib64/heartbeat/cib
1119 ? S 0:01 \_ /usr/lib64/heartbeat/lrmd
1120 ? S 0:00 \_ /usr/lib64/heartbeat/attrd
1121 ? S 0:00 \_ /usr/lib64/heartbeat/pengine
1122 ? S 0:02 \_ /usr/lib64/heartbeat/crmd
to use gfs with corosync then. I will try it out and post the result
here.
But gfs2 uses dlm as the lock manager, and dlm also uses CKPT service. So
eventually you also need the openais package.
DLM seems to have started fine in my cluster

Basically I have been following the doc "Cluster from Scratch Apache in
Fedora 11" at clusterlabs.org website only I am on Fedora 12
