All,
I've inherited a couple of RHEL5.1 clusters and in
an effort to improve their performance have attempted to add a couple of
hueristics to the quorumd section of cluster.conf. The existing quorumd
section is as follows:
<quorumd device="/dev/mapper/mpath2"
interval="1" tko="10" votes="1">
<heuristic interval="2"
program="ping -t1 -c1 216.187.173.1" score="1" tko="5"/>
</quorumd>
When I change that section to:
<quorumd device="/dev/mapper/mpath2"
interval="1" tko="10" votes="1">
<heuristic interval="2"
program="ping -t1 -c1 216.187.173.1" score="1" tko="5"/>
<heuristic interval="2"
program="/path/to/script.sh" score="1" tko="5"/>
</quorumd>
And attempt to load the new configuration using
system-config-cluster (via the file->open menu command) I get the following
error message:
(In a pop-up dialog)
Relax-NG validity error : Extra element quorumd in
interleave
/path/to/config/cluster_v30.conf:2: Relax-NG
validity error : Element cluster failed to validate content
/path/to/config/cluster_v30.conf fails to
validate
The ONLY change I am making from a working config
file is to add the second hueristic to quorumd, so I'm certain that the
validation error is coming from that line. So my questions are two-fold
when I looked around the internet what I could gather is that the entity causing
the XML validation error is missing a field. Is this the case?
Everything I could find in the documentation and looking through this mailing
list leads me to belive that my approach is correct. Second question: is
system-config-cluster just being overly paranoid? I can load the config
file using 'ccs_tool update' from the command line without errors.
Thanks for any help you can
provide!
