  • Exchange Cluster 2003 offline defragmentation

    Hi all,

    I have an Exchange 2003 SP2 Cluster, and need to do an offline defragmentation.
    We introduced an email archiving tool, and have moved about 50% of data off the information store.

    In E2k3 I will tanke offline the information store, and run the defrag.
    As I am running the cluster for half a year now, I am not sure if I can proceed in the same way with a cluster.

    Can I take the information store offline, without triggering any of the cluster functionalities? Failover or something else...

    Thanks for your answers in advance!

    Cheers
    Marc

    If you have plenty of disk space you could create a new mailbox database and move the users into that. Make sure the space you use is supported by the cluster though (i.e. it will failover). This way you keep everything but the users that are being moved at that time, up.

      Hi Andy,

      that is worth a try. Sounds not too bad.

      But I would still like to know, if I can dismount the database without triggering any alert within the cluster. If I can dismount it using the ESM, that would be good to know.

      Thanks!

      Cheers

        If you want to do an offline defrag it is total downtime of the entire Exchange environment. That makes a mockery of the usual reason for a cluster (no downtime).

        To be honest I am not actually sure if you can offline defrag a cluster. It is not something I have ever done.

        However as you are using clustering, that means Enterprise edition. Therefore I wouldn't even be considering it. Another store, move the data, drop the old store. Zero downtime, zero risk.

        Offline defrag is not risk free.

        Simon.

          Jep, thatīs what I have told my boss after Andys post.
          Unfortunately it is his decision to take... :-/

          So I will take the entire system down, and do an offline defrag.

          Will tell you how it ran out...

          Cheers
