Windows 2008 server - disk reserved

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.

What is the status of the disks on cluster administrator?
Online/offline/failed/pending?

John

I'd ask the same questions...What is the status of the disks in cluster
administrator? Online/offline/failed/pending?

Ok, after running the validation tests again, 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.

For Teredo issue, see
http://blogs.msdn.com/clustering/arc...6/8773796.aspx

For your disks, delete the failed/offline disks from cluster adminstrator.
This will cause them to stop showing up "reserved" but of course does not
necessarily resolve your problem. Once you've taken the disks out of
cluster, run thru the validation again for these disks and see if it passes.
If not, you'll likely need to engage your storage vendor.

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.
