Reclaiming Disk Space

Hi.

Groupwise 2014 with SP

One of our sites is down to 12GB of space on their groupwise partition, we have no more space it can use, we've gone around setting up archiving on a lot of PC's even though auto archiving was set it doesn't seem to be doing it? Anyway setting up archiving individually on the archives is working on those mailboxes, they are going down but the space on the server isn't.

I know it only holds one copy etc... so that it's not directly proportional.

But, my question is about Reclaiming Unused Disk Space, is it a safe tool to run? I've not run it before so i'm thinking it's time to give it a whirl and see if it works it's magic on the database, but i generally just want to check that it's a safe tool to use, even if it doesn't claim back much space, it's how likely is it to corrupt the database, if it's a very low percentage then i'll happily give that a whirl Friday evening and see what it does.

The database is currently around 500GB
  • Hi,

    The Reclaim unused space options only affect the wphost.db or wpdomain.db files. As these are fairly small anyway, you will never see much of a gain.

    The GWCheck Reduce only option in the Expire/Reduce settings is the best way to reclaim what space you can.

    Also, are you running on NSS volumes? If so, ensure that "Salvage Files" is set to OFF.

    Cheers,

    Are you running regular GWchecks? If so, which ones?

    Well then time to find out where the space is going. I've found there are
    usually some big chunks that can be found, and to that point I wrote up
    http://www.konecnyad.ca/andyk/gwbig.htm
    I haven't updated it to GW 2014 yet, but the concepts and general places
    to work from are the same, just change ConsoleOne to the new web admin
    and you should be good to go.

  • Hi. Am just reading through your blog here are my first thoughts.

    It runs:- These Weekly
    Default Weekly Maintenance Event
    Default POA Disk Check Event
    It runs this Daily:-
    POA Structure Check which is Analyze / Fix and it just has a tick in structure check and fix any errors found.

    It's been steady for a while now but it's starting to eat up space, the more we put on archiving the more it seems to be eating space it's daft.

    I've got two more disks now on order to change the raid1 pair into a raid10 pair, but realistically we cannot get to the site to do this until at least a week and a half, and it's gone from 12gb to 9.5gb space overnight.

  • Hi,

    You might find this of some use: https://www.novell.com/documentation/groupwise2014/gw2014_guide_admin/data/adm_db_disk_space_reduce_user_message.html

    Specifically this:

    When users archive and empty messages in their mailboxes, the messages are marked for removal from the database (“expired”), but the disk space that the expired messages occupied in the databases is retained and used again for new messages. As a result, archiving and deleting messages does not affect the overall size of the databases.


    Hope that it helps.

    Cheers,
  • Thanks Laura, yeah I've read that in the past, but it does make a difference :)

    The odd little email might not, and it's not the most massive difference, but I've got this one users database down from 40.6GB to 29.3GB currently, and the available space on the Groupwise filesystem has gone up from 9.5GB to just over 15GB :) So it makes a difference. I'm just going to have to pick on a few of our biggest users and do this to get enough space to keep it going until we then double the space via new disks :)

  • Hi,

    Glad that you are getting space back :) The "Reduce Only" option can make a huge difference.

    Cheers,
  • 1 days solid archiving I've gone from 9.5Gb of space up to 28GB of space, and that is more than we had a month ago... So that should keep it going long enough for me to stick the second pair of disks in.

    Then it's rsync it each night for a week to an external backup disk, and then at the weekend, tell it to do a final rsync with GW shut down, then rebuild the disk array and rsync back, and hey presto :) double the space. Well that's the plan.

    That is the 'fun' in the world of databases, where some sort of cleanup
    jobs are needed along the way. I see I need to add another job to that
    list as it is one I have been implementing, a weekend Reduce messages run
    that also takes out the trash.

    And the built in GW archiving will generally take more space than keeping
    the mail within the POA as it is single instance of a message within the
    POA, but copies are made for each archive involved.
    Ex, If we are on the same PO and I send you and Laura a 1MB message, it
    gets stored just once, but when we archive it, it will take 3MB, 1MB in
    your inbox, 1MB in Laura's, and 1MB in my sent items.
