Disk space eaten up with no files RRS feed

  • Question

  • Stand alone exchange 2013 (virtualized on vmware 5.1) - Windows 2012 R2 Standard edtion

    Recently have noticed strange behavior.. of no mails being processed... after troubleshooting reckoned of low disk space on drive where transport queue was...we increased disk size.

    Disk size allocated is 60GB

    transport queue size is approx 4GB and still it shows only 10GB remaining.. as there is no other content than transport queue files.

    Similar is with our database drive.... database size is approx 60GB... (We have enterprise vault hence DB size doesn't increase much)... drive size is 159GB.... but free space is only 13GB... same here no files other than database....(Transaction logs are in different drive.

    Checked if snapshots are there.. or content in recycle bin.. but there is nothing... 

    how to reclaim this space... or get visibility what is eating up this. so much... we can't keep on increase size of disk...


    Cheers VP

  • First check the database size and log folder size by this command

    Get-MailboxDatabase -Status | select ServerName,Name,DatabaseSize,EdbFilePath

    Make sure logs are getting truncated by your backup

    Please check these if database and log files not consuming the space

  • Hi vp98,

    Please check if you have high number of files in count. If yes then it could be the limitation of how files are stored in filesystem.

    Check if there is a difference in 'size on disk' and 'size' property of the folders or files.

    Link below for details:

    I believe you have already checked hidden and system files from Explorer->View->View Tab, note if you have VSS enabled or have system snapshots created it would not show up the count\correct size easily.

    Check if VSS is enabled on the volume.

  • Hi,

    First, you need to verify whether the disk space is used by mailbox database file and queue database file.

    If not, you can use Disk Clean-up to free disk space. For more details about Disk Clean-up, you can ask in the Windows Server forum which is staffed by more experts specializing in this kind of problems.
