Recovering from 109% full disk situation
-
I left ntopng historical data turned on for too long and not surprisingly it filled up the root file system.
It sure seems weird to report 109% of capacity used. This is on a Hyper-V virtual machine, here's a snapshot I grabbed before recovering:
[2.2.2-RELEASE][root@pfSense.trumpetinc.local]/var/log: df -hi Filesystem Size Used Avail Capacity iused ifree %iused Mounted on /dev/ada0s1a 3.9G 3.9G -316M 109% 290k 271k 52% / devfs 1.0K 1.0K 0B 100% 0 0 100% /dev /dev/md0 3.4M 108K 3.0M 3% 34 988 3% /var/run devfs 1.0K 1.0K 0B 100% 0 0 100% /var/dhcpd/dev [2.2.2-RELEASE][root@pfSense.trumpetinc.local]/var/log:Is this peculiar to FreeBSD and/or Hyper-V … or am I just not reading this correctly?
I tried uninstalling the ntopng package - but that, understandably failed. Using ssh I tried deleting one of the larger folders under the /var/db/ntopng (/var/db/ntopng/0) - it freed up around 500MB, but the firewall still would not pass traffic. Restoring back several days seemed to fix the problem.

There is reserved space, so usage can go over 100%.
After deleting ntopng's files, a filter reload (or reboot) likely would have brought things back to a sane state.

Thanks for enlightening me on the 109% full.
We did perform a reboot after freeing some disk, but it did not seem to help. I restored Sunday and Saturday - they too did not work. Restoring Friday night let things get back to norma.
