Description Amit Upadhye 2020-12-09 05:55:33 UTC

Description of problem:

Moving to foreman-2.1 katello-3.16 we experienced hanging tasks on some of our test-systems.

The reason was that candlepin or rather the Artemis-service used by candlepin started blocking requests as soon as the disk-usage rose above 90% (even though this meant that 200GB were still free).

To avoid that users run into this issue, there should be a check to make the root-cause visible.

Version-Release number of selected component (if applicable):

Foreman 2.1(6.8) onward

Observations:
We have a check to make sure the candlepin directory (/var/lib/candlepin) has enough space now and if space is more than 90 PERCENT then it points to https://bugzilla.redhat.com/show_bug.cgi?id=1898605
