    Description

      Race is painful when you switch your cluster from walCompaction=false to walCompaction=true.

      The same FileCompressor instance will use different segmentAwares due to start0() is called twice which leads to inconsistent behaviour and errors during compaction, basically we will try to archive files twice concurrently.

      See reproducer in attachment.
