  1. Customers and resellers are unable to login into Parallels Plesk Panel. The following exception is displayed:

    ERROR: Session_Exception
    Not enough disk space.
  2. Parallels Plesk Panel administrator can login into control panel, but warning is displayed:

    Not enough disk space.


There is less than 5 megabytes of free disk space on disk partition where Plesk's session directory (/usr/local/psa/admin/sessions) is located.


  1. Determine on which disk partition sessions directory is located:

    [root@pp11 ~]# df /usr/local/psa/admin/sessions
    Filesystem           1K-blocks      Used Available Use% Mounted on
    /dev/sda0             10317104  10312421      4683  97% /usr
  2. Free some disk space on the partition.
