    My /usr/tmpDSK is getting almost full, and I am getting a warn about that.
    I have followed this tutorial"
    [Removed - Outdated]
    I have increased the $tmpdsksize= to a value around 8 gb everything looks ok, when i check to my WHM disk usage I see that nothing has changed.
    Even if i redo the process to see if the charges were saved, there looks ok,
    What I should do?

    Hello,

    Please follow below steps to increase the /tmp disk space :

    So log into SSH and SU to root so we may being!
    Code:
     cd /dev 
    Create 100MB file for our /tmp partition. If you need more space, make count size larger.
    Code:
     dd if=/dev/zero of=tmpMnt bs=1024 count=100000 
    Make an extended filesystem for our tmpMnt file
    Code:
     /sbin/mke2fs /dev/tmpMnt 
    Backup your /tmp dir- I had mysql.sock file that I needed to recreate the symbolic link for. Other programs may use it to store cache files or whatever.
    Code:
    cd /
    cp -R /tmp /tmp_backup
    Mount the new /tmp filesystem with noexec
    Code:
    mount -o loop,noexec,nosuid,rw /dev/tmpMnt /tmp
    chmod 1777 /tmp 
    Copy everything back to new /tmp and remove backup
    Code:
    cp -R /tmp_backup/* /tmp/
    rm -rf /tmp_backup
    Now we need to add this to fstab so it mounts automatically on reboots.
    Code:
    vi /etc/fstab
    You should see something like this:
    Code:
    /dev/hda3               /                       ext3    defaults,usrquota        1 1
    /dev/hda1               /boot                   ext3    defaults        1 2
    none                    /dev/pts                devpts  gid=5,mode=620  0 0
    none                    /proc                   proc    defaults        0 0
    none                    /dev/shm                tmpfs   defaults        0 0
    /dev/hda2               swap                    swap    defaults        0 0 
    At the bottom add
    Code:
     /dev/tmpMnt             /tmp                    ext2    loop,noexec,nosuid,rw  0 0 
    Save the file

    Now you can check your /tmp disk space is increases. :)

    Hello :)

    The securetmp script will utilize 1% of disksize with a minimum of 500M and a maximum of 4G, based on the available space on the /usr partition (where the tmpDSK file is stored). You are welcome to manually create a /tmp partition if you prefer to use a larger size.

    Thank you.

    Hello,

    Please perform tune2fs -c for new tmp partition to adjust filesystem parameters.

    Hello,

    /tmp writing process running on server that why you face this issue. Please stop all services then try to backup the /tmp file.

    If still face issue then run below command :

    Code:
     lsof |grep /tmp 
    you will see what processes are still writing and you can kill them: kill -9 PID. or do

    Code:
    umount -l /tmp
    umount -l /var/tmp
    Then try to backup the your tmp directory and proceed for further steps.

    Thanks

    You could modify the following line in your /usr/local/lib/php.ini file:

    Code:
    eaccelerator.cache_dir="/tmp/eaccelerator"
    To:

    Code:
    eaccelerator.cache_dir="/home/eaccelerator"
    Then run the following commands:

    Code:
    mv /tmp/eaccelerator /home/
    /scripts/restartsrv_httpd
    Thank you.
