Disk usage

FreePBX System Administration
1

A few weeks ago (just as I want on holiday) one of my clients mailed to tell me their FreePBX install wasn’t working. I logs in and noticed the disk was full. Since I was one foot in the plane, I expanded the volume and went on with my holiday. Now I have some time and am looking at different installs and see my own install also seems to be getting full. A few screenshots:

My client’s:

My own:

Another client:

The main difference is the first 2 are hosted on a Synology NAS and the last one on a Vultr server.

Main thing I’m wondering is “what is Other” and is there a way to clean files? I have already deleted larger log files

In ocasions when there is a disk storage leak, I normally use the following command to identify which are the folders with larger storage:

sudo du -h -d4 /boot /etc /home /opt /root /tmp /usr /var | sort -rh | head -n30

I ran that command on my own install and it gave me the following list:

5.1G /var
3.2G /var/www/html/admin
3.2G /var/www/html
3.2G /var/www
3.1G /var/www/html/admin/modules
2.6G /usr
1.3G /usr/lib
1.2G /var/lib
599M /home/asterisk
599M /home
597M /var/cache
596M /var/cache/yum/x86_64
596M /var/cache/yum
511M /usr/lib64
480M /usr/lib/firmware
476M /usr/lib/modules
449M /var/lib/mongodb
446M /usr/share
416M /var/lib/asterisk
385M /var/lib/mongodb/journal
358M /var/cache/yum/x86_64/7
350M /var/lib/asterisk/sounds
304M /home/asterisk/.package_cache/npm/6.4.1
304M /home/asterisk/.package_cache/npm
304M /home/asterisk/.package_cache
271M /var/log
244M /home/asterisk/.npm/_cacache
244M /home/asterisk/.npm
236M /usr/bin
235M /var/lib/asterisk/sounds/en

I however don’t know where I can clean up.

It depends on what FreePBX version you are using.
In FreePBX 17 /var/cache/yum can be completly removed (in Debian yum is not used) and MongoDB packages could also be removed.
I also find a bit strange 3.2G for /var/www/html/admin.
In my FreePBX 17 system, with only open source modules, it’s only 372M.
According with @penguinpbx, in a standard 17 install that folder has only 1.3G (see Drive Partition Layout Survey - #7 by penguinpbx).

I’m still on FreePBX 17 and I’m guessing there’s no way to upgrade from this version to Debian?

Are you running FreePBX 17 over CentOS?
Have you made a fresh install or an upgrade?

If your Linux distro is CentOS (which is not recommended/supported for FreePBX 17), /var/cache/yum is something normal to exist.

Regardless the Linux distro you are using, what is not normal in the disk usage that you reported for /var/www/html/admin (3.2G).

I have made a backup of my current install and I’m installing Debian as we speak. We’ll see what happens.
