In situations where the available capacity on one or more disk pools falls below a low-space threshold, the Job Engine engages low-space mode. This mode enables space-saving jobs to run and reclaim space before the Job Engine or even the cluster becomes unusable. When the Job Engine is in low-space mode, new jobs are not started, and any jobs that are not space-saving are paused. Once free space returns above the low-space threshold, jobs that have been paused for space are resumed.
The space-saving jobs are:
Once the cluster is no longer space-constrained, any paused jobs are automatically resumed.
