hy guys,
my colleague gave me a tip, that the stonith ressource on node 1, when node
2 is offline, won't work cause of a false state (cant reach the asm module
of node 2) and so the other ressources (vg, lv) can't start.
Based on this I modified the ibmrsa plugin in following way:
I changed the return value of "/usr/lib64/stonith/plugins/external/ibmrsa"
in line 44 to 0, so that there is no false state for the stonith device and
the remaining node (node 1) can start the ressources.
So this problem is fixed for our needs.
The other question concerning the storage is still open.
Further I mentioned, that I have no problem, when a node loses the
connection to the gateway (ping ressource), but I have a problem with this.
Because when the connection is up again,
the ring stays faulty and won't return. Not even when I manually try to
make the ring clean again with "corosync-cfgtool -r". - I also open a call
@ novell concerning this problem.
The strace ouptut from" corosync-cfgtool -r" can be found in the
attachement.
(See attached file: strace_output_corosync-cfgtool_-r.txt)
thx for replies.

cluster resource [Pacemaker] 2 node cluster with
manager clvm, configuration help
<pacemaker at oss.cl needed...
usterlabs.org>
hy,
as I told you, I am going to test the clvm cluster with the new service
packs vor SLES11 and the HA edition.
The versions in there are following:
"pacemaker-1.1.2-0.2.1"
"corosync-1.2.1-0.5.1"
"openais-1.1.2-0.5.19".
The problem that only one ring is supported by the dlm is now gone and I
have it running with 2 rings right now.
Including a ping ressource, the loss of connection is also covered and
works fine.
The only problem I have is, when I power off the node, which holds the
volume group and logical volume ressources: the ressources on the cluster
go in unclean state (stonith, vg, lv resources).
The failover of the ressources then doesn't work, till the node gets power
again. I maybe think, that this has something to do with my stonith
ressource, because as soon as the asm module gets power again, the failover
of the ressources to the running node works. We already updatet the asm
module to the newest version, but this didn't help.
Another question I have is following: Is it possible, that the cluster
checks the loss of fiber channel connection to the storage. (We are
connected to the storage via fc switches, and have 2 paths) We tried
pulling of the fiber channel connection, and could recognize that our
volume group we defined, fails. The group fails, but no failover happens
nor anything else.
I add my configuration, maybe you see a configuration failure. If you need
log files, please tell me.
Thx for your replies.

hy,
thx for your answers.
I tried out, modifying the crm file, didn't get any new output. I wanted to
use the opensuse packages, because they were newer then the sles11 packages
which are in the hae extension.
finally novell managed to make the sp1 for sles11 and the hae extension
available, i'll download it, and try it out in the next few hours, hope
that it works with the new versions.
we'll see, i'll inform u then.
thx.

Looking again at the code, it is most probably that the package
just can't be used on SLES, i.e. that the python paths for
modules differs. You can verify that with 'rpm -ql | grep /crm/'
and compare the output to the paths from the error message.
