Xenserver pool HA in Cloudstack
Hi,
I have Xenserver cluster setup with 4 Hosts in it. I was wondering about HA configuration of xenserver pool. But at some places I saw that cloudstack HA and Xenserver HA both are different . And One shouldn't use Xenserver HA, since Cloudstack HA is by default active. Is it true?
Yours sincerely,

Hi, Geoff:
We have followed your blog to implement Xenserver pool HA feature, thanks for sharing it.
I have one suggested update to your blog post, in case other people may encounter the same issue we had.
In your script for enabling pool HA, it left HA timeout to the default value. This default timeout value may not be long enough to prevent premature hypervisor self fencing. In our case, all three of our XenServers went into self fencing during a planned NetApp cluster maintenance when cluster head switchover happened.
Here is a Citrix support doc describing how to set new HA timeout values:
http://support.citrix.com/article/CTX139166
Thanks,
Yiping

Posted by Serg Gorodnichy <s....@gmail.com>.
Hi Geoff,
thank you for your article. I'm trying to enable pool HA but ending up with
the following error message:
The restore could not be performed because this backup has been created by
a different (incompatible) product version
I have ACS 4.4.1-NONOSS_3 with XS 6.2 patched up to XS62ESP1013 installed.
I see 2 files were created under MGMT-HA mount, but HA is still not
enabled. Could you please let me know what might be wrong?
Thanks

RE: Xenserver pool HA in Cloudstack
Posted by Geoff Higginbottom <ge...@shapeblue.com>.
Hi Yuri,
To be totally honest, I've not tested upgrading XenServer once the Pool HA has been enabled, but I would imagine you first disable the Pool HA, then proceed with the upgrade, then re-enable HA at the end.
I would still set manage.xenserver.pool.master=false whilst upgrading the Pool Master.
Regards
Geoff Higginbottom

Hi Geoff
If the pool master is managed outside the cloudstack, does it mean that there is no need to set manage.xenserver.pool.master=false when applying patched to the Xen cluster with pool HA enabled ?
Will it just be enough to unmanage the cluster in cloudstack , disable the pool HA on the cluster and proceed with the hotfixes or should I follow the procedure described in the documentation?
Thank you
Yuri

RE: Xenserver pool HA in Cloudstack
Posted by Yuri Kogun <yk...@outlook.com>.
Hi Geoff
If the pool master is managed outside the cloudstack, does it mean that there is no need to set manage.xenserver.pool.master=false when applying patched to the Xen cluster with pool HA enabled ?
Will it just be enough to unmanage the cluster in cloudstack , disable the pool HA on the cluster and proceed with the hotfixes or should I follow the procedure described in the documentation?
Thank you
Yuri

RE: Xenserver pool HA in Cloudstack
Posted by Geoff Higginbottom <ge...@shapeblue.com>.
Hi Ian,
When I say
" If the Pool Master goes down a Slave will take over and all VMs which were running on the failed Pool Master will be automatically restarted on alternate Hosts, but only as long as their Compute Offering had the ‘Offer HA’ feature enabled."
I am saying that if the Pool Master fails, then a new Pool Master will automatically take over and all HA VMs auto restart on alternate Hosts with no admin interaction. The reason for this blog is that since the release of Hotfix XS62ESP1004 if you do not configure Pool HA then in the event of a Pool Master failure you will need to manually promote a new Pool Master.
So as long as you enable Pool HA, you do get a self-healing cluster from the point of view that a new Pool Master is allocated, but yes you do then manually need to fix the failed host then enable it to re-connect to the pool by disabling HA, then re-enabling HA which is a manual process.
Regards
Geoff Higginbottom

Agreed. Very good article. I have a question though - is it really appropriate to describe this as “self-healing”, when there are manual steps to be performed in case of failure of the Pool Master?
Typically, I use this term to refer to situations where the master fails,
a different host gets elected master, and all is well. Then when the old
master is brought back online, it just becomes a normal pool member, like the rest of the hosts. No “emergency mode”, etc…

Re: Xenserver pool HA in Cloudstack
Posted by Ian Forde <if...@marketo.com>.
Agreed. Very good article. I have a question though - is it really
appropriate to describe this as “self-healing”, when there are manual
steps to be performed in case of failure of the Pool Master?
Typically, I use this term to refer to situations where the master fails,
a different host gets elected master, and all is well. Then when the old
master is brought back online, it just becomes a normal pool member, like
the rest of the hosts. No “emergency mode”, etc…

The link you referenced is a design doc for a possible future feature, this is NOT in CloudStack as of today.
@Sonali,
As promised, here is a link to the article I have been working on today covering the use of XenServer HA with CloudStack,
http://shapeblue.com/cloudstack/xenserver-native-ha-with-cloudstack/
In summary if you have installed XS62ESP1004 then you MUST start using XenServer HA on your XenServer Clusters, if you don’t, and the Pool Master goes down, no new Pool Master will be elected.

RE: Xenserver pool HA in Cloudstack
Posted by Geoff Higginbottom <ge...@shapeblue.com>.
Hi Yuri,
Whilst testing this, I killed off the Host Masters approx. 10 times, and on about 2 occasions the old Pool Master did automatically re-join as a slave, but on the other 8 occasions they did not.
I think it depended on how long they were down for, so a simple reset of the host was OK, but if it was down for say 10 mins then the recovery steps were required etc.
I have applied patches up to and including XS62ESP1014 but you say you have only applied up to XS62E014 which is pre SP1 and more importantly pre XS62ESP1004 which is the patch which triggers the requirement for this configuration.
Regards
Geoff Higginbottom

Hi Geoff,
Great article. Just wanted let you know that I tested the configuration on my test environment and everything worked as you described, apart from the 'Recovering from Host Failures' bit.
In my case the former master came up after reboot and joined the pool as a slave. No manual steps were needed. Below is the extract from the messages on the host.

@Suresh,
The link you referenced is a design doc for a possible future feature, this is NOT in CloudStack as of today.
@Sonali,
As promised, here is a link to the article I have been working on today covering the use of XenServer HA with CloudStack,
http://shapeblue.com/cloudstack/xenserver-native-ha-with-cloudstack/
In summary if you have installed XS62ESP1004 then you MUST start using XenServer HA on your XenServer Clusters, if you don’t, and the Pool Master goes down, no new Pool Master will be elected.

Hi,
I have Xenserver cluster setup with 4 Hosts in it. I was wondering about HA configuration of xenserver pool. But at some places I saw that cloudstack HA and Xenserver HA both are different . And One shouldn't use Xenserver HA, since Cloudstack HA is by default active. Is it true?

Subject: Xenserver pool HA in Cloudstack
Hi,
I have Xenserver cluster setup with 4 Hosts in it. I was wondering about HA configuration of xenserver pool. But at some places I saw that cloudstack HA and Xenserver HA both are different . And One shouldn't use Xenserver HA, since Cloudstack HA is by default active. Is it true?
Yours sincerely,

Sonali,
There have been some changes recently and as luck would have it today I am working on a blog article for www.shapeblue.com covering the correct way to configure HA in XenServer. It's due to go live later today, I'll respond to this thread once it's live.
Regards
