Description
On a benchmarking engagement, customer allocated 2x the estimated raw data size for disk space. However their accounting didn't take into account the requirement to get 3x the total disk space. Under this condition, engine had trouble compacting the files due to lack of disk space. However there was no alert or end user indication that indicated disk space was low. We need to add more alerting to indicate disk space is low on a cluster even if the steady state without compaction is in a comfortable range.
We need a new alert that indicates that "free space on disk for vbuckets is below the total size of the bucket data on 1 or more nodes". This will clearly indicate we have an issue and confusion will be prevented.
