Comment on Exchange 2010 RTM DAG using Server 2008 R2 – Part 1 by dkroep

I think I get it now. The FSW is mainly used to get a majority i thought the replication was also a part of the FSW's job. (Explains the resource question) But the replication NIC takes care of that. So when it goes down you still have 2 nodes replicating which can both have mounted databases in use. But when the FSW is down you can't get a 2/3 majority and that could cause split brain if something happens to the replication NiC.

Thanks for your time you've helped a lot.

I did not utilize the script, but the manual process did work for us in our OCS R2 environment.

The user account does not seem to work well with me. Does not allow me to logon, and I am sure about my password. Anyone else face this??

Nothing really happens if the FSW goes down if you still have majority. Majority is 50% + 1. So if you have 2 DAG Nodes and 1 FSW, if your FSW goes down, you still have 2 nodes up so you still have majority. Just bring back up the server that has the FSW and all is well. The FSW doesn't take up much space at all. It's nothing you have to plan for. It's probably only a few MB in size (I'd have to check our server). The FSW takes up no real resources at all, nothing you would have to account for.

If for some reason, your FSW server dies, just set the Set-DatabaseAvailabilityGroup cmd to create a new FSW on a different server.

Hi,

1st let me say Great! guild,

i followed this guild and i eventually am able to complete the intallation, however i am unable to start any of the 2 services, they start and stop , 1st i was using a certificate with my oce server pool, then i lately change it to another certifictae with the GC server name and sip.domain name and ocspool name as SAN.

this is the error i get from the event log:

The Microsoft Office Communications Server 2007 R2, Group Chat Server MGCLOOKU could not stop due to an exception Object reference not set to an instance of an object..

An error MGCLOOKU is stopping due to an unhandled exception.

Update to my service none starting issues, 1st i changed the account service to administrator which had more rights than other account , and started the services and they started, but they only start one at a time, the two services would not stay on running at the same time, then i added all rights to the ocschat account and restarted the services again this time they started,

so i am not sure what account member is missing yet that stoped the GC services from starting, i will use process of elimination later to find that out….

but now i still cannot logon to the GC server as administrator
i get:

Cannot sign in. Your sign-in address, server settings, or password may be incorrect. If your sign in information is correct and the problem persists, please contact your system administrator.

and nothing on the GC Event log server, any ideas?

i also am now running the SQL on the same server as the GC, i previously was using the same as my OCS front end server,
Question,…what is the pool name when u are using an SQL server on the same GC server which is a memeber server? is it the FQDN of the server it self?….my OCS pool name is ocspoo.ct.com…..my GC server name is Main.ct.com….my GC instance i created was name GCPool on the member server. what then is the Pool name of this GC SQL? or do i have to create a pool using the installation cd? cos right now i had to fill in the gap using my ocs pool i created for my FE server…

First of all thanks for the article Elan really nice.
I am going to install the FSW on a server outside of a 2 noded DAG like you did but what happens when the FSW server goes down?
Is it easy to recover?
How much HD space is required for the FSW?
Does the FSW take a lot of the server's resources?
