Appendixes are nice to fill pages. The book is available in print also;

So basically I have two questions now:

shouldn't be there?
* Is there any way to get my nodes back to a clean status?
Thanks in advance,

Following up on my message that I've sent yesterday. In my 2-node test
cluster, sbd stonith works in an excellent way. In my customers 3-node
cluster it almost works in an excellent way. That is: I've got one node
that is in an uninterrupted STONITH loop. It comes up with a status

Yes, one should almost think so. That's why I think the SBD STONITH
plugin is a _huge_ step forward. :-) It just doesn't look doable to

Hi,
I have a small test cluster, using two nodes with SLES 11 + SLES HAE,
completely patched up to date. I've noticed that if one of the nodes
goes down, the cluster looses quorum (crm_mon -i 1 on the remaining node

Hi,
I'm still struggling with clvmd and trying to understand what's
happening, see the description I've sent earlier this week. Now I've
found something more specific, please tell me if I've found a bug or
not: (using SLES 11 with HAE)

Hi,
I'm working on different Xen HA projects, but sometimes get the idea
that I'm the only one on the planet doing such projects. Is there anyone
on the list involved in Xen HA projects? I would appreciate having the
opportunity to exchange some thoughts now and then.
Thanks,

Hi,
I'm trying to set up OCFS2 in a pacemaker environment (SLES11 with HAE),
in a 3 node cluster. Now I succesfully configured two volumes, the dlm
and the o2cb resource. But: if I shut down one of the nodes, at least
one other node (and sometimes even two!) is fencing itself.

Hi Tino,
I'm not Linbit, so you're probably not interested in my answer ;-P

I'm using it in Pacemaker, with clone resources for dlm and clvm and
individual resources for each of the logical volumes and it works
perfectly. Some cluster related stuff in my environment worked on cLVM
only, such as pvcreate on multipath devices (might be my ignorance

Hi,
I hope someone has configured the APC Master Stonith resource (which you
would use to have pacemaker to a device like the APC switched rack PDU),
as I have a - probably extremely stupid - conceptual question about it.
When I look at the options the resource has, it allows me to enter

Hi list,
I know there are a few people from my country on the list (and some
Germans that read Dutch). I've written a rather complete document that
describes how to create a high availability solution for Xen virtual
machines. About 80 pages if you also count the pictures. If anyone likes

Following this procedure in different environments, I always end up with the
