Description of problem:

Creating directories and files fails on the NFS mount, if selinux is enabled on NFS-ganesha server. However, it succeeds when selinux is permissive.

Version-Release number of selected component (if applicable):
ceph version 10.2.10-11.el7cp 

How reproducible:
3/3

Steps to Reproduce:

1. Install nfs-ganesha-rgw and edit the ganesha.conf file as per doc https://access.qa.redhat.com/documentation/en-us/red_hat_ceph_storage/2/html-single/object_gateway_guide_for_red_hat_enterprise_linux/#exporting_the_namespace_to_nfs_ganesha
2. Enable selinux. (setenforce 1)
3. Start the Ganesha service "systemctl start nfs-ganesha", it starts successfully.
4. Mount using NFsv4, try creating directories and files. (it fails with cannot create directory ‘dir1’:Read-only file system)

[root@magna085 ubuntu]# mount -o vers=4.1 magna085:/ mnt1
[root@magna085 ubuntu]# cd mnt1
[root@magna085 mnt1]# ls
[root@magna085 mnt1]# mkdir dir1
mkdir: cannot create directory ‘dir1’: Read-only file system
[root@magna085 mnt1]# 



Actual results:
Not able to write on the NFS mount 

Expected results:
Should be able to write on the NFS mount
