# Low Disk Space on filesystem.root

I’m receiving the following warning on my TensorBook:

“Low Disk Space on filesystem.root - The volume filesystem.root has only 77.3 Mb disk space remaining”

The TensorBook (April 2022) is running Ubuntu 20.04.4 and Lambda Stack.

John,

The normal Ubuntu install has all the software in the same partition.

(/, /usr, /tmp, /var, and /home). (There is also a separate small /boot/efi partition that you do not need to worry about unless it gets full).

You may have a second drive on your system, that you could move your home or other data.

The following would show what you have for drives and if they are mounted.

```
$ lsblk | egrep -A 10 “^sd|^nv”
```

To see what directory is taking up the most space:

(The -x and --exclude is to eliminate other directories).

```
$ sudo du -x --exclude=“/proc” -s /* | sort -n
```

- Then you can pick a sub directory to see what in there is taking the most space and continue.

```
$ sudo du -s /home/* | sort -n
```

And additional tool will display it graphically:

```
$ sudo apt install xdiskusage
$ sudo xdiskusage /
```

Solutions:

1. You could potentially move data to another drive.
2. Remove unneeded data or software, or archive it to a remote drive/server.
3. Compress data (especially large text-based data).
4. Get a larger drive.

Thank you, Mark. The problem turned out to be in the /var/log syslog file. I had screen sharing enabled, which resulted in many attacks on my system from outside agents. The attacks were unsuccessful, but each attempt was logged in syslog. I cleared syslog to zero and disabled screen sharing – problem solved. Thanks to Lambdalabs support (Calvin Wallace) for help in solving this issue.
