/dev/mapper/vg_ha-slash filling up fast

FreePBX 13.0.195.17
Asterisk 13.19

I’ve got a Freepbx HA configuration where it’s showing /dev/mapper/vg_ha-slash is going from 50% to 75% in a 12 hour period. I deleted a bunch of httpd error logs and that reduced it to 50% but less than 10 hours later it’s back to 71% except this time the log files are not the culprit. I’ve tried running du -kscx * from the root to see what folders are using a bunch of disk space but nothing shows that it can account for the vanishing disk space.

Any suggestions as to what to look for?

As root

du -xh --max-depth=1 /|sort -h

the last line is the biggest, so iterate

du -xh --max-depth=1 /var/|sort -h

probably

du -xh --max-depth=1 /var/log/|sort -h

when you are at the end of the tree, look for the biggies.
