How to solve jenkins 'Disk space is too low' issue?

Question

I have deployed Jenkins in my CentOS machine, Jenkins was working well for 3 days, but yesterday there was a Disk space is too low. Only 1.019GB left.

Answer 1

This is actually a legitimate question so I don't understand the downvotes, perhaps it belongs on Superuser or Serverfault. This is a soft warning threshold not hard limit where the disk is out of space.

• For hudson see where to configure hudson node disk temp space thresholds - this is talking about the host, not nodes

Jenkins is the same. The conclusion is for many small projects the system property called hudson.diagnosis.HudsonHomeDiskUsageChecker.freeSpaceThreshold could be decreased.

In saying that I haven't tested it and there is a disclaimer
