You have a <cman/> to close the cman stanza in cluster.conf, but no
actual <cman parameter1=1 parameter2=2> to open it. Is this correct?
The cman stanza is where you would define expected_votes on the
cluster, so not having this present is perhaps the reason why ccsd
believes the cluster is inquorate?
thanks. I didn't see that. I've been using the GUI tools to
manipulate the cluster.conf file so that I could hopefully avoid
omissions just like this one. Since obviously that isn't working, it
seem to me that I'm going to have to shut all the cluster services
down, edit the clutser.conf file by hand, propagate it out there. or
is there a quicker way to do that with cman_tool or somesuch?
Thanks in advance
I tend to use the GUI tools myself for that same reason, but it's
happened to me before as well (and by the looks of one or two of the
posts here, we're not the only ones).
So I guess conga and the system-config-cluster aren't 100% at building
config files that work. Sometimes they get in a twist and you have to
get your hands dirty :-)
To fix this, I think (from memory) you need to copy
/etc/cluster/cluster.conf to an alternate location on any one of the
nodes (i.e. cp /etc/cluster/cluster.conf /tmp)
Then modify the alternate version from having <cluster
config_version=xxx> to be config_version=xxx+1 (or otherwise increment
the number to one that is higher than has been previously used). For
example you would change <cluster config_version=37> to <cluster
config_version=38>.
Then add the appropriate <cman> line with all the options that are
appropriate (including expected_votes). To give you an example of where
the line should sit, here is an excert from a working two-node cluster:
</clusternodes>
<cman expected_votes="1" two_node="1"/>
<fencedevices>
In otherwords, put the <cman> after </clusternodes> but before
<fencedevices>.
Then run:
[root@node01 ~]# ccs_tool update /path/to/fixed/cluster.conf
It should distribute the new file to all nodes in the cluster.
