Re: [ClusterLabs] Two related Cluster

2016-05-18 Thread ‪H Yavari‬ ‪ 
Hi,
Thank you for reply. 
I tested the first method "multi-site cluster". it was ok with ticket manually 
assignment. But I had issues with running Booth.I tested second method 
"constraints and attributes". I make a cluster with 4 nodes and define some 
constraints for nodes. But I have problems with node relations now.
I was searching in the docs then I found 
"http://clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Pacemaker_Remote/ch05.html".I
 thinks this is very close to my answer. Do you offer this solution?
Regards,H.Yavari

I think a single cluster using node attributes should be a lot easier to
understand and maintain, so I'd recommend that solution if it works out
for you.

Re: [ClusterLabs] Two related Cluster

Hi,
I begin to test. So I defined 2 clusters that are include: Cluster 1: App1 and 
App3   Cluster 2: App2 and App4
Now If I want enable IPaddr as a resource on clusters, this resource will 
assign to both nodes. while ip float should run only on App3 and App4.Should I 
use constraints to limit ip float resource to only one node in each cluster? so 
I should do this for other resource too and then use Booth for CTR?Any hints or 
sample save my life :)

I would say you have 2 options:

- 1 cluster with node attributes and these dummy resources I had
described previously in the thread. (Unless
  anybody has a better idea how to tackle this).
- 2 small clusters and use booth

Which one is better depends e.g. on where your servers are located -
timing/reliability issues with certain network connections
between them?
Bringing up the booth infrastructure is of course an issue as well...

Hi,
Thank you again. 
Servers are in one location. I read a few about Booth. But I'm afraid of 
ticketing. This servers are very sensitive. 
So with this situation you offer Booth or using attribute method??

Why do you want to have two clusters with the same set of nodes? A
single cluster can do everything that the two clusters could. If you
want to run certain resources on only some of the nodes, you can achieve
this with node attributes and location constraints.

Kristoffer

I mean when in cluster X , node A is online and node B is offline, in cluster Y 
nodes will have same status.

I'm not sure what you mean by a node changing, but there is booth [1]
which enables the transfer of resource ownership between multiple
clusters.
