Hi,

I am trying to configure a 2012 Hyper V cluster but I am getting problems when trying to use the shared storage. Here is what I've done so far:

1. Installed 2012 server OS on 2  hosts (same specs)
2. Enabled the ISCSI service on both hosts
3. Created a host group on the SAN and added the two hosts into it
4. Created a virtual disk of 1.2Tb and assigned it to the host group
5. From the two hosts, I can see the virtual disk created in step 4 from Disk Manager
6. Initialized the disk from one of the hosts and did a format (NTFS) and assigned it a drive letter (on both hosts)
7. Enabled Failover Cluster tool from both hosts
8. From one of the hosts, I created a cluster
9. In the cluster wizard, I included both hosts
10. Cluster is created successfully and the two hosts are seen as Nodes
11. In the storage option (of the failover cluster) I added a disk (which is the one in step 5)

Now the problem is here. Let's say that I did all of this from host 1...

12. When I create a virtual machine, the wizard asks you to choose between host1 and host 2
13. If I choose to create the virtual machine on host 1, I can see the disk mentioned in step 5 and store the files there
14. But if I choose host 2, I cannot see the disk mentioned in step 5
15. If I go on host 2 > Disk Management.. I cannot set anything on the disk because an error pops out saying that this disk is in use by a cluster and that I need to switch the disk into maintenance mode

I then found that I need to use a quorum disk so I created another disk and called it Quroum (3Gb) and set the quroum disk by the cluster quorum wizard. This led to nothing and I remined with the same problem.

Could someone please help me and tell me what I am doing wrong? A step by step HOWTO would really be appreciated as I did not found any specific help on the web.. everyone saying different things :/

Thanks and looking forward to hear from anyone :)

Regards,
Justin

What you missed is that you didn't make your volume where you store the VMs a cluster shared storage volume. Remove your existing VMs, because when you go to a CSV the path changes to c:\clusterstorage\volumename .
Volumename

Your quorum disk only needs to be 100 mb or smaller. I haven't figured out how small you can make it. No need to waste space on it.

Hi kevinhsieh,

thanks for your reply. The problem I am facing now is when I try to create a new storage pool, there is no storage subsystem listed.

Any ideas?

Thanks for your help

Why are you creating a new storage pool? You can re-use your existing 1.2 TB volume for the CSV.
