mdatp directory consume lot of space in linux.

Hi,

 We have configured yum repo for defender in linux, in client machine installed defender and it uses 46GB of space in below path still increasing the space, Can you help on this please?

 

Below path using 46GB.

/var/opt/microsoft/mdatp/definitions.noindex

 

  • Ram_roshith, it's not expected for the "Security Intelligence Updates" (aka signatures/definitions) to take up that much of disk space.
    Check that the permissions are correct.
    You could try changing the locations of the path where they are downloaded to, use the 'mdatp definitions' command, and look at the 'path' switch.
    If this doesn't help, please open a Microsoft CSS Security MDE support ticket.
    Thx,

      yongrheemsft Thanks for the update, please find below output of mdatp definitions command.

       

      [root@Testsrv ~]# mdatp definitions
      Expected one of:
      update Check for security intelligence updates
      path Manage security intelligence updates path

        Hi Ram_roshith, actually, it was to find the following command:
        mdatp definitions path set --path /new location/
        where /new location/ is the path where you might have the right permissions.
        Then restart wdavdaemon
        Thx.
