Subject RE: Management Server won't connect after cluster shutdown and restart
Date Fri, 29 Aug 2014 20:16:54 GMT
Hi Ian,

I've seen this kind of behaviour before with KVM hosts reconnecting.

There’s a select …. WITH UPDATE; query on the op_ha_work table which locks the table, stopping other hosts updating their status. If there are a lot of entries in there they all lock each other out. Deleting the entries fixed the problem, but you have to deal with hosts and vms being up/down yourself.

So check the op_ha_work table for lots of entries which can lock up the database. If you can check the database for the queries that it's handling - that would be best.

Also check that the management server and MySQL DB is tuned for the load that being thrown at it.
(http://support.citrix.com/article/CTX132020)
Remember if you have other services such as Nagios or puppet/chef directly reading the DB, that adds to the number of connections into the mysql db - I have seen the management server starved of mysql connections when a lot of hosts are brought back online.

Hi Ian,

So the root of the problem was that the machines where not started up in the correct order.

My plan had been to stop all VMs from CS, then stop CS, then shutdown the VM hosts.  On the other end the hosts needed to be brought up first and once they are ok then bring up the CS machine and make sure everything was in the same state it thought things were when it was shutdown.
 Unfortunately CS came up before everything else was the way it expected it to be and I did not realize that at the time.

To resolve I went back to my CS db backup from right after I shut it down the MS, made sure the VM hosts were all as expected and then started the MS.
