Description

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.
Example:

The glusterfs process spawned by the mount command has the "--dump-fuse" option as seen below:
root 27505 1 0 Oct04 ? 00:00:30 /usr/sbin/glusterfs --dump-fuse=dumpfile --volfile-server=10.70.43.18 --volfile-id=/arbiter /mnt/arbiter
