Root Space 100% - Critical

Hi, everybody.

We (the “Gesinco” IT team) are in a rather conflictive situation.

It seems the /dev/mapper/s7_freepbx-root partition on our Sangoma FreePBX distro (version 12.7.5-1805-2.sng7) is 100% full. We’ve been having alerts at 95%, 96% but it always came back to 90% or so.

Now, it has reached 100% and we’ve been having trouble using the web GUI for administration. Thankfully we are still operational, but it’s something we’ve got to solve.

The question is: How can we expand the size of our root partition in our current filesystem configuration ? Or at least, How can we free some space on the root partition.

As you can see, we have a separate device for call recordings. Then, the tmpfs partitions and the boot partition:

Filesystem Size Used Avail Use% Mounted_on
/dev/mapper/s7_freepbx-root 34G 34G 214M 100% /
devtmpfs 5.8G 0 5.8G 0% /dev
tmpfs 5.8G 4.0K 5.8G 1% /dev/shm
tmpfs 5.8G 481M 5.4G 9% /run
tmpfs 5.8G 0 5.8G 0% /sys/fs/cgroup
/dev/sdb1 1.8T 102G 1.7T 6% /var/spool/asterisk/monitor
/dev/sda1 497M 220M 278M 45% /boot
tmpfs 1.2G 0 1.2G 0% /run/user/2
tmpfs 1.2G 0 1.2G 0% /run/user/0

We were surprised to notice how exponentially the used space on root has been growing.

Maybe there is something we’re missing, maybe something has been filling a great deal of space on the partition and we can’t tell what it is.

Any help or advice will be welcome.

Thanks in advance.

I’d check logs in /var/log/asterisk and backups in /var/spool/asterisk/backup

Since recordings are on a separate device, I’d say those are your likely suspects.

I had a system yesterday suddenly fill up /run but after reboot it has not happened again.

never had / fill before.
