Description of problem:
systemctl restart nmb.service
SELinux is preventing /usr/sbin/nmbd from 'read' accesses on the file nmbd.pid.

*****  Plugin catchall_boolean (47.5 confidence) suggests  *******************

If you want to allow samba to share any file/directory read only.
Then you must tell SELinux about this by enabling the 'samba_export_all_ro' boolean.
You can read 'samba_selinux' man page for more details.
Do
setsebool -P samba_export_all_ro 1

*****  Plugin catchall_boolean (47.5 confidence) suggests  *******************

If you want to allow samba to share any file/directory read/write.
Then you must tell SELinux about this by enabling the 'samba_export_all_rw' boolean.
You can read 'samba_selinux' man page for more details.
Do
setsebool -P samba_export_all_rw 1

*****  Plugin catchall (6.38 confidence) suggests  ***************************

If you believe that nmbd should be allowed read access on the nmbd.pid file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep nmbd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
