    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?

    Hi,
    I have a similar problem. The disk is listed as 'reserved'. Please let me know what you think. Thanks,

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

    Re: Windows 2008 server - disk reserved

    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.

    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.

    Re: Windows 2008 server - disk reserved

    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.

    Re: Windows 2008 server - disk reserved

    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.
