Description Saurabh 2015-07-13 09:48:15 UTC
Description of problem:
created a volume of 6x2 type, kept the configuration of the volume as default, mean to say that acls disabled and root_squash disabled.

Executed pynfs MKSOCK test and it failed

Version-Release number of selected component (if applicable):
glusterfs-3.7.1-9.el6rhs.x86_64
nfs-ganesha-2.2.0-5.el6rhs.x86_64

How reproducible:
always

Steps to Reproduce:
1.create a volume of type 6x2, start it
2. configure nfs-ganesha, mount the volume with vers=4
3. execute pynfs with MKSOCK as parameter,
time ./testserver.py  -v --outfile ~/pynfs.run.2 --maketree 10.70.44.92:/vol3  --showomit --rundeps  MKSOCK  > /export/pynfs-results-mksock-4.log

Actual results:
result of step3, 
[root@rhsauto009 mnt1]# cat /export/pynfs-results-mksock-4.log

From the brick log --> 

[2015-07-13 14:51:26.192714] E [MSGID: 113022] [posix.c:1165:posix_mknod] 0-vol3-posix: mknod on /rhs/brick1/d1r13/tree/socket failed [Permission denied]

Brick process denies creation of the socket files.

Same test passes on our setup (which has selinux disabled)  - 

[root@192 nfs4.0]# ./testserver.py  -v --outfile ~/pynfs.run.1 --maketree 192.168.122.205:/vol1 --showomit --rundeps  MKSOCK

Will check after enabling selinux.
