This is a a known issue with write allocate file systems and snapshots. I haven't seen this before on v13 without any snapshots. A few questions: - How many file systems? - How old are the file systems? - How much churn has there been on the file system? - Was this an upgraded v6 or created as v13? - How many files on test? ... as well as any other things that occur to you to characterize the file system.
