While testing out a new configuration of XCache, I ran into this error message: ``` 181209 23:08:36 8835 XrdFileCache_Cache::ConfigParameters(): pfc.diskusage should have lowWatermark < highWatermark. ``` I was quite befuddled, as the `pfc.diskusage` setting is reasonable: ``` pfc.diskusage 0.90 0.95 ``` Turns out that `totalSpace` is multiplied by the watermarks -- and I had set the cache directory to something that didn't exist, resulting in the high-water mark and low-water mark both being set to zero. Let's just fail instead (or, lacking that, allow this strange configuration to be non-fatal). -- You are receiving this because you are subscribed to this thread.
