GMS - Disk Space usage

Hi,

We are in the process of migrating from a BES solution to GMS. This weekend We added a user to the GMS and their account started to sync.

In Groupwise the mailbox claims to be just over 4GB in size with around 8000 items.

For three days the GMS complained about a high number of attachments being synced for this user, in some cases up to 400/min Avg, and this has eventually now subsided.

The problem I have now is that in the last 3days, whilst this sync took place I have lost over 30GB of disk space on the GMS server (/var/lib/datasync/mobility/attachments/.... ) and it's looking like I'm going to have to extend the sda2 partition.

We did notice that the GWCleanup script we run states that the same mailbox is around 33GB, but this is not reflected in the GW POA Server UI where it states 4GB.

Could you explain the discrepancy in the sizing differences of the mailbox and the space taken in the GMS please?



As an additional question, does the GMS sync the full mailbox from the GW POA or only the items based on the number of days to sync? Can the number of days to sync be set differently per user or even per device? (21 days is fine for a mobile but longer would be great for Outlook/autodiscover on the desktop)


Thanks

Mark

    Where did you check that? Did you also run a gwcheck to update mailbox
    statistics?

    Shared items? They only count for the owner.

    If you are just looking in the GW Admin interface, that only gets updated
    when the Audit GWCheck runs, which is why it is a part my recommended
    maintenance jobs. Otherwise you get this situation you have.

    How large are you allowing messages? And what date range are you keeping
    in GMS? I have a client with much larger mailboxes but what shows in
    GMS is so much smaller even at a 50MB limit in GMS (for the usual 30
    days)

    gwcheck runs weekly and the user has not had 29GB of mail since it ran. 4GB Sounds about right.

    Somebody told me that Groupwise deduplicates data in mailboxes. No idea if this is true.

    Hi,

    We only allow 10MB max and on the GMS I have dropped the number of sync days down to 21 days.

    This particular mailbox though has a lot of email in Japanese. Could the character set have any influence in this issue?

    Thanks all for reples

    Well, yes and no. Groupwise never duplicates data to boot, but of course
    GMS isn't groupwise. In Groupwise, when user A sends a 1GB mail to user
    B, the total amount of data in GW is 1GB, the mail exists only once.

    Obviously, when you sync that mail to two mobile phones, you end up with
    2GB, and so you do in GMS, as there is no shared storage.

    I don't think it would make a big difference. More likely this user
    has just gotten a large number of large messages recently.

    Does the user have many folders shared from others and is the shared
    folders option turned in GMS?

    Make sure you have a good round of schedule maintenance running on your
    system and that you check the resulting logs to make sure everything is
    being properly taken care of.
