How to reclaim freed disk space after Telegraf filled all swap on Raspberry Pi Zero running Raspbian 9 Stretch?
/var/swap grew to 14GB, so I disabled swap with
dphys-swapfile and deleted the swap file.
cat /proc/swaps shows no open swap files, but
df -h still reports 100% in use.
du -m | sort -n shows 14GB at
., but I can't see a way to reclaim any of that freed space. Tried rebooting. Can't install
lsof because...Zero disk space.
