To check how much space on the Solid State Drive (SSD) is already in use or still is at your disposal, you must first connect via SSH to the Gigaset T300/T500. Then following command can be issued:

df -h

[root@T300 ~]# df -h
File system Size Used Avail Use% Mounted on
/dev/sda3 5.3G 3.4G 1.7G 67% /
/dev/sda1 99M 9.6M 85M 11% /boot
/dev/shm 497M 0 497M 0% /dev/shm

When issuing this command you can see from left to right the following data:

  • Total size of hard disk
  • Used space
  • Still available disk space
  • Used space in %

Find large files

If the hard disk is getting full, it may be worthwhile to search for the cause. A first step here would be to look at, what files take the most space.

Therefore the following command can be used on the SSH console.

ls -lahS $(find / -type f -size +10000k)

Here is a list of all files generated are larger than 10MB, in descending order according to their size.

Remove unneeded files

With the standard Linux Commands, unnecessary or unwanted files are found. These can be old log files, tcpdumps, etc.
These unnecessary files can then be removed or moved over a file transfer to an external system. Only delete files for which you are 100% sure that they are not needed for the operation of the Gigaset T300/T500. The deletion of critical system files can not be undone, and can only be fixed by reinstalling the system.

If the hard disk of a system is 100% full, this will lead to a shut-down of the system.
