    might be wrong but, i think those jailed accounts are the cause?
    So, whats the best way around this please? im gonna say probably increasing the size?
    If so, how please?

    Hi,

    It cannot be the virtfs, the reason being it is on /home and it is s separate partition..
    Try releasing the space from the unwanted log file. This should be sufficient if those tend to get heavy with disk space utilisation ..

    Hi,

    Check the logs in the location:

    # cd /var/log/ && du -sch *
    # cd /usr/local/apache/logs && du -sch *
    # cd /usr/local/cpanel/logs && du -sch *

    You see the space it is utilizing...

    Hello,

    You can ignore those warning messages, and proceed to further examine the disk usage. EX:

    Code:
    du -sh /*
    Thank you.

    and now this...
    Sorry for the inconvenience!
    The filesystem mounted at / on this server is running out of disk space. cPanel operations have been temporarily suspended to prevent something bad from happening. Please ask your system admin to remove any files not in use on that partition.

    EDIT

    Looks like its the backups that are taking up the space, i had them at /backups/
    so i deleted some of them and it let me back in to cpanel, I thought that having
    them there would have just used up what ever space that was free on the drive
    evidently not, so i have moved them to /home/backups/ in the hope that that will
    suffice.....

    Hello,

    You may also want to consider storing backups on a remote server, or adding a new drive to the server for backup storage. Storing backups on the /home partition is discouraged and can prevent quotas from working properly.

    Thank you.

    Hi, sorry for the late reply..

    It looks like i can only have it set to a remote server as a secondary backup place only not as a primary
    Adding a new disk is not an option :(

    Oh, wait, i have just had another look, please let me know if i go wrong here?

    1). If i set backup DIR to /home/backup/
    2). Backup transfer to another server
    3). Have Retain backups in the default backup directory.

    Would that still mess with the quotas? or do i need to put the backup back to /backup and have the backups
    removed after transfer? thus saving on that partition space?

    You can uncheck "Retain backups in the default backup directory." and the backups will only remain stored on the remote destination.

    I recommend choosing the local directory with the most disk space, and then disabling the "Retain backups in the default backup directory." option. This will help ensure the local backups are successfully generated before the archives are moved to the remote destination. Once the transfer to the remote destination completes, the backups are then removed from the local directory (e.g. /backup).

    Thank you.
