Cache inode entries can exist without the corresponding file being open. So I don't think there is a relation between Entries_HWMark and the number of file descriptors a process can open. > (2) For the given system limit, what is the cache inode setting. We are > using Ganesha 2.1. The number of cache entries is probably related to the available system memory rather than the number of files a process can open. Frank or anyone else, what is a good value on systems with 128GB or 256GB system memory?
