Disconnected XenServer 6.5 Master server

Hello,

Master server got disconnect (problem with HDD's) and now, can't
stop/restart some of VM's.

There is enabled HA, but they are not restarting on another server.

Anyone have idea, how to do it manually?

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.

Hello,

pool master and slaves all is ok. Master new server, and slaves working

xe pool-ha-disable
The operation could not be performed because HA is not enabled on the Pool

I restarted cloudstack-management service, but anyway, VM's showing online

Re: Disconnected XenServer 6.5 Master server

Posted by Dag Sonstebo <Da...@shapeblue.com>.
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

Posted by Dag Sonstebo <Da...@shapeblue.com>.
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”).

    Master server got disconnect (problem with HDD's) and now, can't
    stop/restart some of VM's.
    
    There is enabled HA, but they are not restarting on another server.
    
    Anyone have idea, how to do it manually?
