Uninstalling Last Node in Cluster - What Happens to the Shared Disk?

    Hello all,

    I'm wondering what happens to a cluster's shared disk when you remove the
    last node in the cluster? The Windows cluster that we have is no longer
    needed and we would like to deactivate it, but the shared disk does contain
    a good deal of information on it that we would like to keep. Once the
    cluster is deactivated, does the shared disk become unusable and require
    re-partitioning/formatting or does the Windows disk manager have a facility
    to import the disk? I've got backups of the data, but it's a pain to
    restore from backup so I would prefer to not have to do it if possible. Any

  2. To the best of my knowledge, MSCS doesn't do anything to the shared disk
    when the cluster is ultimately dissolved. It should be a simple matter of
    presenting/attaching the disk to another server or simply re-accessing the
    disk from one of the existing "node" servers and manipulating the data

    Keep in mind that most of my experience is with CREATING clusters and not
    destroying them. :) You've covered your bases by ensuring that you have
    valid backups, so let it fly...

  3. If you change the LUN masking so that only one server can attach to the
    disks, then you should be fine to leave them attached to the last node.
