SELinux is preventing /usr/sbin/glusterfsd from 'unlink' accesses on the sock_file 204632be8e98e418b07cf4a7dc8a06a0.socket.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that glusterfsd should be allowed unlink access on the 204632be8e98e418b07cf4a7dc8a06a0.socket sock_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 glusterd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
