Re: Disconnected XenServer 6.5 Master server

[Dag Sonstebo]

OK, cool. What is host 3? (select * from cloud.host where id=3 in the db). 
Is this the old poolmaster? If this is the old poolmaster you probably want to 
put this into maintenance mode in CloudStack.

Re: Disconnected XenServer 6.5 Master server

[Dag Sonstebo]

I would first of all check your new master thoroughly with the below commands, 
then check your XS slaves - do a “more /etc/xensource/pool.conf” on all of them 
to check that they all agree point to the new poolmaster (in fact carry this 
step out on the new master as well). If not you may have to do a “xe 
pool-recover-slaves”. There may be other steps required as well – you may have 
to disable HA temporarily (xe pool-ha-disable) + do some xe-toolstack-restarts.

Once you are fully happy the XenServer cluster is healthy you might have to 
restart your cloudstack-management service.

Re: Disconnected XenServer 6.5 Master server

[Dag Sonstebo]

Are the other XS hosts showing as healthy in CloudStack? This can sometimes be 
a XenServer issue – where a new poolmaster isn’t assigned properly.

Check the current state of your cluster (“xe host-list / xe pool-list / more 
/etc/xensource/pool.conf”) + if it’s not healthy you may need to do a “xe 
pool-designate-new-master” (or worst case “xe 
pool-emergency-transition-to-master”).
