Re: clustering question



MNS does, but MNS with FSW (which the post was about or read it wrong) only work on 2 node clusters. Longhorn changes that, but we don't have Longhorn yet :) FSW and MNS = 3 nodes :) Sorry for the confusion.

MNS without FSW is best served with 3 nodes or any odd number after that - agreed.

Actually, MNS requires at least 3 nodes and you can have up to 8 in 2003. You can setup a 2 node cluster as MNS but a failure of one node will cause the failure of the other.

There's some good articles on MNS on this TechNet site.

MNS currently only works on a 2 node cluster (that will change in the future with Longhorn). More answered below...

I am trying to learn and test clustering using windows 2003 enterprise edition and currently just an MSA 500.


Cool, great hardware. HP is an excellent resource and they will answer most any question you have.

What I want to understand is....should I be using MNS or the physical disk as the quorun resource...from what I understand it seems that if you have a 2 node cluster you should use the physical disk as the quorun resouce and if its a multi node cluster you should use MNS.


If you want to avoid a single point of failure with regards to your Quorum drive - yes.

Also I did not set up MNS right at the start ? I used the physical disk as my quorum resource ( shared disk) , how do I revert back to MNS ? any easy way ?

Not a problem, you can switch to MNS after the fact. Easy http://msmvps.com/blogs/clustering/archive/2006/07/09/Majority-Node-Set-_2800_MNS_2900_-with-only-2-nodes_3F00_.aspx


is this a good link ?

No really the complete story, see the link I posted above.



I am still a little cofused as far as setting up groups are concerned...i set up a cluster group and a MSDTC groups for SQL 2005....the MSDTC group now owns the shared disk resource instead of the cluster group...is this normal ?

I can answer that it depends. See http://msmvps.com/blogs/clustering/archive/2004/10/25/16672.aspx


Finally what is this stuff about the file share wintness....are people using it in production ?


We are using it on 14 clusters currently. I love it, works great.

Any help will be appreciated...
thanks !
