> It's possible that GEODE can throw a DiskAccessException stating that the
> current file system usage exceeds the critical threshold, but the exception's
> message states that the file system usage is UNDER the critical threshold, as
> follows. This appears to be only an error in what is logged and GEODE really
> is over critical.
> org.apache.geode.cache.DiskAccessException: For DiskStore: dmDiskStore_3604:
> Critical disk usage threshold exceeded for volume
> /var/vcap/data/scratch/serialParRegHABridgePersistParOffline-0516-200217/vm_2_bridge3_disk_1:
> the file system is 5% full, which exceeds the critical threshold of
> 5.203678%.
> The problem is that GEODE rounds the file system usage before logging it in
> the message in the method DiskUsage.update(float, float), and this can cause
> the problem when it gets rounded down:
> double use = 100.0 * (total - remaining) / total;
> recordStats(total, remaining, elapsed);
> String pct = Math.round(use) + "%"; <=====
