Mount Point on the 2003 cluster

[ashley75]

I need to create mount point on Windows 2003 cluster, I did follow the below link, but have question since I am not clear:

1. So let say if you have 5 luns that all of the nodes on the cluster can see, I would think you have to create the first disk first let say G drive and mount all other luns onto this G drive, is it correct?

2. Assume you got all of the luns mount to disk G, so if the lun that allocated to Disk G went bad, all other four luns that were depend on G went bad as well?

3. Once you got mount point completed, will you see disk G with 500G from explorer or you only see 100G physically?

thanks

Yes, you would actually create the mount point in the G Drive.
So what you would do is initialize the new LUN in disk administion. Create new partition, when you get to the assign drive letter phase and choose "Mount in the following empty NTFS folder." Click browse, choose g: drive and create a new folder called, something like, clusterDateMountPoint.

Yep...

3. Once you got mount point completed, will you see disk G with 500G from explorer or you only see 100G physically?
For some reason only the 100G physical. But I believe when you add data to the mount point is doesn't take away from the physical disk free space.

I would only use mount points if you have an issue with running out of drive letters. If you set up mount points in a cluster, remeber they have to be set up a cluster resources as well....

We have just such as issue on a SQL Server where we are running out of drive letters and will be setting up mount points to hold the database files.

One thing that I did notice is that you will want to make the mount points dependant on the G drive, and any software which will be using those mount points (such as SQL, Exchange, etc) should be dependant on the mount points as well as the G Drive.

When I was first testing the mount points in a cluster I noticed that the SQL Server didn't validate that it was dependant on the mount points like it does on the drive letter. I had sure to setup the SQL Server to be dependant on the mount points as well as the drive letters so that SQL wouldn't start before the mount points are online.
