Hi,
Posted this in gluster-user mailing list but got no response so far, so i post in gluster-devel.
I found this test suite (https://github.com/Hnasar/pjdfstest) for me to test fuse mount gluster and there is some reported issue from the test. One of the error is as follow.
When i chmod 7777 to a file in fuse mounted gluster volume. the return stat value for the file is not 7777 instead of 4777.

Performing this operation in normal ext4 system produce correct result.
root@ubuntu16d:/mnt/g310mp# touch ~/testfile

Besides 7777, 3777 also an issue. The stat return is 0777.
My OS is Ubuntu 16.04 and my gluster version is 3.10.1 and the it is a simple volume with default parameter.
root@ubuntu16d:/mnt/g310mp# gluster volume info
Volume Name: g310
Type: Distribute
Volume ID: 114666c6-4884-436a-81a8-2deb3c0923ba
Status: Started
Snapshot Count: 0
Number of Bricks: 1
Transport-type: tcp
Bricks:
Brick1: 192.168.36.130:/mnt/g310brick
Options Reconfigured:
transport.address-family: inet
nfs.disable: on
for me, i seldom use those mode (3777 & 7777) but i cannot say for sure for others. So is this something i should be concerned about?
