Hi list,
I'm running a HA 2 node active / passive cluster with drbd and mysql.
I was told about the ocf monitoring function of the yet available
mysql ocf script.
well if its an OCF script it needs to implement some kind of
monitoring - its mandatory
whether the monitoring it does is any good is another question...
Could you tell me the advantages or disadvantages of implementing
this monitoring function?
its not optional :-)
I mean surely it does have benefits, but what if I my php
webapplications e.g. generate too much load, too large and complex
queries and the timeout value exceeds?
Then the server would restart or failover and then that would repeat
itself on and on and my ha-cluster wouldn't be a hacluster anymore.
Have you any experience what possible things could happen to a mysql
server and what would be the reasons for hang-up, crash, etc...?
Problem is, I can't estimate the load or amount of queries the
application will generate, as I don't have much experience in this
field and the DBs will grow over time.
Should I implement ocf monitoring or rather not?
I'm very thankful for any advice or hints about this matter, where
to get more information, or personal experiences with the stability
of mysql servers.
Thanks
Lino
