Hi, I am running ganesha 3.5. I have a directory structure such that it has 25000 directories with each one of them contain 500 files. The ChunkSize is set to 1000 and Entries-HWMark is set to 50000 in the ganesha configuration. I run a script to list all the 25000 directories. I ran the list command three times. No other clients were interacting with server. Through the stats tool, I retrieved the chunk count value. 1st Run: Chunk Count: 58335 2nd Run: Chunk Count: 69792 3rd Run: Chunk Count: 73270 From my understanding, the Chunk Cache stores the directory information about a directory. So with 25000 directories with 500 files each, ideally the chunk count should be around 25000. One for each directory. And on subsequent runs, it should not increase. I have not configured the Chunk_HWMark value. So it is set to the default 100k. I suspect there is some chunk ref leak that is causing the chunk count to grow.
