[Sonali Jadhav]

Hi,

Has anyone managed to update/add doc for upgrading xenservers (like from 6.2 to 
6.5) with pool HA configured ?

Hi Remi,
I am interested in the doc update as well.  Please include how to enable poolHA 
as part of the upgrade process.  I am assuming one must first upgrade to a 
version of ACS that supports it.
thanks,
Carlos

Re: XenServer upgrade in CloudStack environment

[Remi Bergsma]

Yes, I think it does. This article was written before mayor changes were made 
(who elects the new poolmaster and such). Now that we should use XenServer 
poolHA, this procedure also should be altered accordingly. 

When I have some spare time, I’ll document how to properly do it with regards 
to poolHA being turned on. If you have questions before that, just ping me.

Remi

Hi,

I did the same as Martin at CS 4.5.1 and it went OK. Does this depend 
on CS version?

Vadim.

This is a mandatory step that disconnects all xen servers in the cluster
from while upgrade is going on.

You can go through

XenServer upgrade in CloudStack environment

[Mārtiņš Jakubovičs]

Hello all,

Yesterday I upgraded one of my CloudStack Cluster's which run on 
XenServer. As XenServer dokumentation suggest, after applying patches, 
need to restart a host, and first must be pool master server. I set 
master server to maintenance mode in CS, when all instances migrated I 
restarted a host. After some time I start to receive e-mails from CS, 
that other hosts in cluster are down too, not only a master server. My 
compute offerings are HA enabled so I receive e-mails with failed 
restart attempt on HA instances. At least, when master come online CS 
didn't restart any instances and I get away with just a little scare.


What is correct way to do upgrade no XenServer hosts in CloudStack 
environment? Patches, like XS 6.2 SP1 
 require to restart pool 
master first.


I use ACS 4.3.2 with XenServer 6.2.

Best regards,
Martins
