Expected Behaviour:

PiHole normally uses very less boot disk, I'm running PiHole in Proxmox LXC container. Previously i never faced such an issue of boot disk overflowing. please help to resolve this disk shortage issue

Actual Behaviour:

The boot disk is full and PiHole crashed over night after an update to V6, lost network since PiHole crashed now after restart the PiHole is working but the boot disk is still full

Debug Token:

Your FTL.log file is humongous!

Let's try to make some room, shear off the most recent 500 entries to keep, and get rid of the rest.

Please try:

sudo systemctl stop pihole-FTL

followed by

sudo rm /var/log/pihole/*.gz

sudo tail -500 /var/log/pihole/FTL.log > FTL.keep.log

sudo rm /var/log/pihole/FTL.log

and then

sudo systemctl start pihole-FTL

Thank you for the guidance, the size has significantly reduced.

Please see the output of ls -lah /var/log/pihole/

Hope this wold not reappear.
