We are trying to execute Filebench tests with NFS Ganesha and it most of the time hangs (filebench process stuck in D state) and does not complete the test. I have observed the following errors in ganesha.log: 2020-02-25T02:43:49Z : epoch 5e543710 : fsvm23 : ganesha.nfsd-34[::ffff:172.30.0.111] [svc_598] 405 :fsal_close :FSAL :open_fd_count is negative: -1 2020-02-25T02:46:27Z : epoch 5e543710 : fsvm23 : ganesha.nfsd-34[::ffff:172.30.0.111] [svc_731] 2144 :mdcache_lru_fds_available :INODE LRU :FD Hard Limit Exceeded, waking LRU thread. 2020-02-25T02:46:28Z : epoch 5e543710 : fsvm23 : ganesha.nfsd-34[none] [cache_lru] 1388 :lru_run :INODE LRU :Futility count exceeded. Client load is opening FDs faster than the LRU thread can close them. I was searching in the ganesha community for any similar issues and found these: https://bugzilla.redhat.com/show_bug.cgi?id=1713261 which is fixed by Frank in : https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/455570/ This patch is not in present in our repo yet and I was thinking of cherry-picking this change into our FSAL_VFS which is causing the issue. Frank/Soumya, Can you confirm if this fix is going to resolve this issue and if I cherry pick this alone or is there other changes required to resolve this issue please?
