This is a bug in dht it seems like. It is stripping PHASE1 flags unconditionally.
(gdb)
1212 DHT_STRIP_PHASE1_FLAGS (&local->stbuf);
(gdb) p local->stbuf.ia_prot
$18 = {
suid = 1 '\001',
sgid = 1 '\001', <-------
sticky = 1 '\001', <-------
.........
}
(gdb) n
1213 dht_set_fixed_dir_stat (&local->postparent);
(gdb) p local->stbuf.ia_prot
$19 = {
suid = 1 '\001',
sgid = 0 '\000', <-------
sticky = 0 '\000', <-------
...
This is leading to 7777-->4777(gdb)
1212 DHT_STRIP_PHASE1_FLAGS (&local->stbuf);
(gdb) p local->stbuf.ia_prot
$18 = {
suid = 1 '\001',
sgid = 1 '\001', <-------
sticky = 1 '\001', <-------
.........
}
(gdb) n
1213 dht_set_fixed_dir_stat (&local->postparent);
(gdb) p local->stbuf.ia_prot
$19 = {
suid = 1 '\001',
sgid = 0 '\000', <-------
sticky = 0 '\000', <-------
...

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.

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: onfor 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?Cw
