Windows 2008 cluster disk reserved

Postby guest » Thu Dec 29, 2011 9:54 am

I have 2 Windows Server 2008 servers and I'm using a Dell Equallogic SAN. these 2 servers are setup as a cluster. I originally configured them a few months ago and then I didn't touch them for about 2 months. Now I went back to them and all of the disks are showing up as reserved on both servers. There's no options in disk management, everything is greyed out.

I have tried to take the SAN offline, bring it back online and then bring the servers up 1 at a time. that didn't help.

It's the same for all of the SAN disks. I contacted Dell Equallogic and they do not see a reservation on the SAN. They asked me to contact Microsoft.

I verified that the Cluster service is running.

I also tried using "cluster node w2k8 /clear:3" where 3 is the number of the disk.

I also tried running the Validation tests again.

Ok, after running the validation tests, here's what FAILED:

1. NETWORK
-Validate IP configuration
Found duplicate IP address fe80::100:7f:fffe%12 on node mail3.test.com adapter Local Area Connection* 11 and node mail4.test.com adapter Local Area Connection* 11.


Local Area Connection 11 on MAIL4
Adapter Name Local Area Connection* 11
Adapter Description Teredo Tunneling Pseudo-Interface
Physical Address 02-00-54-55-4E-01-00-00
Status Not Operational
IP Address fe80::100:7f:fffe%12
Prefix Length 64

Local Area Connection 11 on MAIL3
Adapter Name Local Area Connection* 11
Adapter Description Teredo Tunneling Pseudo-Interface
Physical Address 02-00-54-55-4E-01-00-00
Status Not Operational
IP Address fe80::100:7f:fffe%12
Prefix Length 64


I have no idea what the Teredo Pseudo interface is.

2. STORAGE

Validate File System
Failed to online cluster disk 0 from node mail3.test.com, failure reason: The requested resource is in use.
An error occurred while executing the test. The string is null or empty. Parameter name: message

Validate Simultaneous failure
Failed to arbitrate for cluster disk 0 from node mail3.test.com, failure reason: The requested resource is in use

---------------------------------------------------------------------------------
After using the CLUSTER command, on Mail3 I'm able to access 2 of the disks by going to My Computer. However, 2 of the disks show up as failed in Disk Management and all 3 disks show up reserved.

If I go to Cluster Management, it shows as only 1 disk being OFFLINE on Mail3. The other disks show up as being Online.


Under Cluster Events, i see:

Event ID 1069
Source: Failover clustering
Cluster resource 'Cluster Disk 3' in clustered service or application 'Cluster Group' failed.

Event id 1037
Source: Failover clustering
The file system for one or more partitions on the disk for resource 'Cluster Disk 3' may be corrupt. Run the Validate a Configuration wizard to check your storage configuration. Optionally, you may want to run Chkdsk to verify the integrity of all volumes on this disk.

Event id 1038
Source: failover clustering
Ownership of cluster disk 'Cluster Disk 3' has been unexpectedly lost by this node. Run the Validate a Configuration wizard to check your storage configuration.

Found answer in another forum:

Sounds like stale PR....easiest is to use cluster.exe CLI to try clearing the PR. Here is a sample command

cluster node w2k8-cl1 /clear:3

3 = the number of the disk as seen in the disk Management interface.

You can also re-run all the validation storage tests ensuring you clear the check box in the wizard allowing the validation to run against all storage. Part of the validation process for storage is to clear all PRs on the drives.
---------------------------------------------------------------

After clearing the reservations, I went to Cluster Management and 2 of the disks showed online, the 3rd one showed offline and I was able to select the disk and put it online.

Then I ran the validation tests again and they all passed.

Apparantely it's normal for Windows 2008 disks to show up as reserved, according to Microsoft.

You can stop the cluster service in Failover Management on one of the nodes and then the other server should take over the drives. If you start the cluster service, that server will not automatically take over until you stop the cluster service on the other node.
