The VXFS fsal is not yet ported for 2.3 or 2.4, so I am not able to check any performance diff with that FSAL. I will see if I can compaire performance with VFS fsal and ext4 fs on latest kernel (3.18.30) for 2.2. and 2.4 My attempt of compiling it failed for now with following errors, 14/04/2016 19:50:46 : epoch 570fa73e : tsserver : ganesha.nfsd-11841[main] vfs_lookup_path :FSAL :CRIT :Could not get handle for path /home/tushar/export, error Function not implemented 14/04/2016 19:50:46 : epoch 570fa73e : tsserver : ganesha.nfsd-11841[main] posix2fsal_error :FSAL :CRIT :Mapping 38(default) to ERR_FSAL_SERVERFAULT On Thu, Apr 14, 2016 at 8:25 PM, Tushar Shinde <[email protected]> wrote: > On Thu, Apr 14, 2016 at 6:16 PM, Malahal Naineni <[email protected]> wrote: >> Both are tunables in V2.3 version.
