Comment 3 for bug 1905581

Another work around to this issue is to simply delete the collectd samples database on the active controller using the following commands.

sudo pmon-stop collectd
sudo pmon-stop influxdb
sudo rm -rf /var/lib/influxdb/data/collectd/"collectd samples"
sudo pmon-start influxdb
sudo pmon-start collectd

Of course the last week of samples data is lost but the root fs space is recovered.

Currently assessing if additional measures need to be taken.

There is no plan to move the influxdb into its own filesystem as an update to address this issue.
That sort of fix would be implemented as an enhancement feature outside the scope of this report.
