    When I logged onto WHM today I saw the error message "The last attempt to update cPanel & WHM was blocked.". When I view the current disk usage in WHM I see this...

    /dev/sda3 9.8G 6.9G 2.4G 75% /usr

    How do I rectify this situation so I can continue to get updates?


    I did search the forums and saw a related thread from a year or o back but it did not offer any help to me.

    I'm running into the same problem and there is enough disk / inodes available when I begin.

    Here's a df -h and df -i I took while upcp running:

    Hello :)

    You will need at least 3G of free space for the "/usr/local/cpanel" directory. This is referenced in our change log:

    Fixed case 135913: Increase update/install blocker to 3GB from 1.6GB for /usr/local/cpanel.

    Thank you.

    The primary issue I see is that your /usr partition does not use the recommended size when utilizing advanced partitioning:

    Advanced Partitioning

    Ideally, you should always use the recommended partition setup as referenced here:

    Installation Guide - OS Configuration

    Without repartitioning, your only alternative is to remove or move existing files from the /usr partition to free up space. Have you checked to see what is taking up the most space on that partition? This document can help with that:

    Manage HD Space

    Thank you.

    Re: The last attempt to update cPanel & WHM was blocked.

    Ouch. Last week it was only 1.6GB needed.

    - - - Updated - - -

    Thank you for the links. Unfortunately the 10GB /usr partition is exactly how Softlayer provisioned my cPanel servers, apparently before the recommended space was announced to be 16BG (or perhaps they just didn't know that bit of info when they provisioned my dedicated servers).

    This is truly a dilemma, because I think we've cleaned up as much of the /usr partition as possible. Repartitioning would mean an OS reload, and that would create many hours of downtime and kill my small business.

    Looks like the only option left is to move and symlink mysql somehow, which makes me really nervous :(

    Re: The last attempt to update cPanel & WHM was blocked.

    How does one go abut repartitioning. BTW the partitions were set up at the default values by my server host (softlayer) when I leased my server. Perhaps if they are using non-recommended settings as their defaults, someone from cPanel ought to enlighten them!

    Question is how do I reallocate the disk space? I have a huge amount of unused space in /dev/sda8 /home and would like to reduce that and increase the volumes that are short.

    Repartitioning isn't really practical without reinstalling the OS. That being said, I don't really see any data that you could move to another partition. Unfortunately, backing up or transferring your accounts and reinstalling the OS with the recommended partition setup is really the best route to take to address this issue.

    Thank you.

    So us long time customers...have accounts that were set up with the "Correct partitions sizes" at the time.

    I would suggest that the Staff at cPanel come up with a non destructive fix. Perhaps a setting allowing us to configure a user account in home (with lot's of space) that can be used to perform the upgrade.

    Other than that. Without support, why pay for this?

    Agree 100%. A lot of us have been using cPanel for many years. We had our servers set up to the recommended parameters when they were provisioned. Changing the rules in the middle of the game without regard for your long time custom,ers is pretty much telling us that we do not matter. This is absolutely 100% an issue for cPanel to address and to do so extremely quickly.

    Someone from cPanel needs to be come actively involved in this thread and take ownership of the issue immediately.

    Just an update.

    I when back and forth with SoftLayer and cPanel. Both had a look at the server. But the issues is still not resolved.

    Again I urge cPanel to publish a non destructive fix.

    You folks understand your software and it's requirements and are best suited to solving this issue. Please tell us you will help!

    I recommend opening a feature request via:

    Submit A Feature Request

    This will allow other users to vote and add their feedback to the request.

    Thank you.

    Hi kernow, I had mistakenly thought of /var instead /usr in my previous post , so moving mysql would not be a solution since that exists in /var and the issue is actually that cPanel now wants more free space in /usr in order to update. (But thank you for making a suggestion and providing the link you did).

    As with other users who have been with Softlayer (formerly ThePlanet) and paying cPanel licenses for many years there, Softlayer provisioned all of my latest servers in year 2012 with a 10GB /usr partitions and now I'm stuck at 11.46.15 unless I either buy new servers that aren't in the budget and migrate everything or reload OS (which would kill my business especially at holidays due to downtime involved) , and so my only practical hope at the moment would be if cPanel would please make it so that updates only required 1.6GB of /usr free as it was the standard needed just 3 weeks ago.

    After upping to 11.46 build 15 I was suddenly hit with this newest requirement of 3GB /usr free without warning and it has put me in a very difficult situation.

    As others have said - I plead with cPanel to publish a non destructive fix.

    Is it possible at all for cPanel to go back to just the 1.6GB free required in /usr that it was a few weeks ago?

    I cannot seem to free-up more than 2.4GB in /usr on my servers. :(

    well this is fookered up...... I just had this server re provisioned in the last year and now you want me to destroy the work? WTF... Worst part is that it is shutting down WHM to resellers as the stupid thing fills up now..

    There must be a better way here...

    Hi cPanelMichael,

    I'm trying to submit a feature request right now with the subject:

    Work-around for cPanel not updating if /usr has less than 3GB free

    (as shown in attached screenshot)

    But it just sits and churns forever.

    Can you recommend a subject that would be more suitable / friendly with the feature request system?

    Thank you.

    I put in a ticket. Went around and around. Then Chris Dillon Technical Analyst III of cPanel, Inc. got involved and gave me the steps to move /usr/local/cpanel into my /home. I am running the update now. I would suggest that Chris publish the steps here to help out others.
