Title: Apparently I am using 109% of my Disk Space?
Post by: JRC on June 08, 2021, 03:05:46 am

So I went to install a plugin on my opnSense box, and got an error that I did not have enough free space, that I had -4Gb free.

The DF commend returns:

Code: [Select]

:/ % df -h
Filesystem                     Size    Used   Avail Capacity  Mounted on
/dev/ufs/OPNsense               50G     50G   -4.0G   109%    /
devfs                          1.0K    1.0K      0B   100%    /dev
tmpfs                          8.2G    564K    8.2G     0%    /tmp
devfs                          1.0K    1.0K      0B   100%    /var/dhcpd/dev
devfs                          1.0K    1.0K      0B   100%    /var/unbound/dev
So I am using more than 100% of the drive??

How do I clean this up?

The issue appears to be flowd.log in my logs folder, it's nearly 30Gb in size.

How do I set it so that this log is rotated at a much smaller size, say 10mb?

Same here.

Digging into the code, flowd log files (`/var/log/flowd.log*`) appear to be managed by `/usr/local/opnsense/scripts/netflow/flowd_aggregate.py (https://github.com/opnsense/core/blob/stable/21.1/src/opnsense/scripts/netflow/flowd_aggregate.py)` which should be keeping a maximum of 10 files of 10 MB each.  I can't see any other process that tidies up these logs, so it's possible the daemon has fallen over and the rc script (https://github.com/opnsense/core/blob/stable/21.1/src/etc/rc.d/flowd_aggregate) managing the process never properly recovered.

Manually running `/usr/local/opnsense/scripts/netflow/flush_all.sh all (https://github.com/opnsense/core/blob/stable/21.1/src/opnsense/scripts/netflow/flush_all.sh)` should tidy things up.

Sorry, in my case, Sensei was filling up the HDD.
It was running in Monitoring mode and somehow its DB grows indefinitely.
