Development Management has reviewed and declined this request. You may appeal this decision by reopening this request. Build version : glusterfs-3.12.2-20.el7rhgs.x86_64 Mounting the volume with the "-odump-fuse=PATH" mount option is successful. The mount command generates a binary file with "PATH" as the file. Example: # mount -t glusterfs -odump-fuse=dumpfile 10.70.43.18:/arbiter /mnt/arbiter The above command generated a binary file with the name "dumpfile". Using "parsefuse" to view the fuse-dump in a human readable format it can be seen that the FUSE traffic b/w kernel and glusterfs-client is logged in the fuse-dump.
