The server does not have enough free disk space.
Check disk usage:
# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/pl-var 129G 129G 0 100% /var /dev/mapper/pl-root 96G 12G 79G 100% / /dev/sda1 190M 19M 162M 100% /boot tmpfs 3.9G 0 3.9G 0% /dev/shm
- Free up some space or increase the disk size. Also
du -sh directory_pathcan be used to find the disk usage of directories.
