When you want to erase a full partition on cPanel, you may be wanting ultimately to free up more space on your directories. If you haven’t performed your scheduled system maintenance and general housekeeping for your computer setups, you may be getting a message that warns you that you’re about to use up all your space on your main user partition.
If you want to create a separate partition for your cPanel, you either have to reformat your whole computer or clear the partition cPanel is on and start over from scratch. Once you’re installed cPanel again, your system may run more smoothly sicne you’ve freed up a lot of space.
So if you’re having a problem with disk space, try clearing a full partition. How do you do this?
There are a few possible solutions. Usually, the /var directory fills up first. This is because the /var directory holds all of the system logs.
Keep in mind that this shows the space that is used and available in each directory, as well as the file sizes of each file in the current directory.
Once you’re done with bringing up the space for each directory,
|tail -5000 filename > filename.new
mv filename.new filename
The /usr directory also fills up due to Apache. To look at the Apache logs, run the following commands:
Take note that the the logs/error_log or logs/access_log files are sometimes very large. At this point, you can delete them or use the tail set of commands that are described above.
Another solution you can try is to clear up disk space. Here’s how:
Since cPanel is often installed on the /usr partition and it is typically small, your /usr partition can quickly reach 100% capacity.
Cleaning up Disk Space
You can find the core files in:
The name of the core files will follow this format.
where # is the number of the process that died.
You can safely remove these files.
Fixing the Issue
Forcing a cPanel update has fixed the issue.
Adjusting cPanel Notifications
In the Tweak Settings part of cPanel, you can adjust notifications for certain disk usage and other alerts. You need 10% free or at least 500MB for any partition containing cPanel. If the partition contains other items, like MySQL, you may want to have more space.
