What clogs the Freepbx root partition?

Question

freepbx

Good afternoon. Freepbx question.
Installed Freepbx on sangome. The problem is that the freepbx-root partition is being clogged with something unknown. at what Home and Boot are not occupied and the free space does not decrease. Test PBX, five extensions, two trunks. There are almost no calls. 20 gig took a day. Previously, there was a 50 gig lvm partition, it clogged up in a week. df -h shows that the partition is occupied by 100 percent, lvdisplay shows that only 5 gigs are occupied in all folders.
Expanded to 100g. currently occupied by 20 gig.
Either this is normal and freepbx needs more than 50 gigs, or it's rubbish.
lsof | grep deleted doesn't help.

Answer 1

Something stuffed in /var , not otherwise. For example, Asterisk logs, call recordings uploaded by CDR. I would look in /var/log/asterisk and /var/spool/asterisk first.
