Exchange 2010 runing out of Space RRS feed

  • Question

  • Hello everyone,

    I need some help with the problem we are having. As the subject says we are running out of space here fast, so, I would really appreciate if some can help me out.

    Here is how our Exchange 2010 is setup.

    - Mailboxes on a physical server

    - CAS is on Hyper-V

    - We have four DB that are mounted (one for US (USDB), three for remote locations users (RDB1, RDB2, RDB3)

    - USDB, RDB1 & Public folders are on the same drive. That drive is 375GB.

    This drive is running out of space. On this drive

    USDB = 290 GB

    RDB1 = 79.1 GB

    Public folder = 368 MB

    So, as I write this, out of 375GB we only have 4.49 GB left and the space is reducing very fast.

    Now, so far I have been transferring users email to their personal folder that resides on their local hard-drives and also deleting some old emails accounts but this does not seems to help. Even when I purge the disabled mailboxes from the "Disconnected Mailboxes".

    Some one from another thread said something about "WHITE SPACE". So, used that command and this is the result:

    Command

    -Get-MailboxDatabase -Status | select
    name,@{l="Size";e={$_.databasesize.togb()}},@{l="White
    Space";e={$_.availablenewmailboxspace.togb()}}

    It gives the following information:

    NAME                                       SIZE                               White Space

    USDB                                        268                                  27

    RDB1                                        73                                     31

    So, my question is:

    - Considering the size of the DB is this white space considered very large/big ?meaning it only gives number but it does not provide any information as to how much space these numbers are taking.

    - Is it worth remove these white space? meaning is it going to make any difference as to increase some space on the drive?

    - If it is worth it then I would really appreciate if someone provide the steps on how to remove these white space.

    I would really appreciate if someone can shed some light on it. If I have missed out on any information then please do let me know.

    Thank,

    Wasim

  • Hi

    I think that I provided that script for someone in the past, not sure if you got it from one of my posts.  The white space is in GB so it's about 10% of the database. 

    You will not be able to run an offline defrag of that database as you will need about 250GB free space - so you are going to need some extra storage in your server.

    Yes, it could be yours. I got it up from one of the threads when i was looking for a solution to my problem.

    I found another script from the aforementioned link that also works great like your and gives little more information:

    Here is that script

    Get-MailboxDatabase -Status | ft name,databasesize,availablenewmailboxspace -auto

    This script gives white space in GB.

  • You need to offline the mailstore to shrink it.

    http://exchangeserverpro.com/defrag-exchange-2010-mailbox-database/

    This will give you some breathing room, but you need to get more storage for that server.

  • Thanks for the reply. I will try that after reading that article.

    Any idea how much those white spaces are taking?
