Hi Jeff,
thank you for the hint. I set Entries_HWMark = 100 in MDCACHE Section of ganesha.conf and upgraded ganesha to 3.2 this weekend. Cache Pressure warnings still keep accuring, but not as frequent as before. Is there another suggestion I did miss?
Great. If it doesn't help, then it would be good to see the "ganesha_stats inode" output. That script is part of the nfs-ganesha-utils package. The output from my (idle) server looks like this: ----------------8<------------------- $ ./ganesha_stats.py inode Timestamp: Tue Apr 14 15:24:18 2020795806304 nsecs Inode Cache statistics Cache Requests: 0 Cache Hits: 2412 Cache Misses: 0 Cache Conflicts: 0 Cache Adds: 193 Cache Mapping: 386 LRU Utilization Data FSAL opened FD count : 0 System limit on FDs : 524288 FD usage : Below Low Water Mark LRU entries in use : 12 Chunks in use : 0 ----------------8<------------------- That should tell us something about the cached inodes that ganesha is holding onto. -- Jeff Layton <jlayton@redhat.com>
