Re: fstest for fuse mount gluster

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

Will update bug with same info

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.

root@ubuntu16d:/mnt/g310mp# touch test
root@ubuntu16d:/mnt/g310mp# chmod 7777 test

Performing this operation in normal ext4 system produce correct result.

root@ubuntu16d:/mnt/g310mp# touch ~/testfile
root@ubuntu16d:/mnt/g310mp# chmod 7777 ~/testfile
root@ubuntu16d:/mnt/g310mp# stat ~/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?
