Description of problem:
The glusterd daemon does not have permission to write to the socket /var/run/glusterd.socket due to SELinux constraints. This is similar to the bug in 911480, but that report has no information about how to solve the problem.

How reproducible:
All servers I have have this problem. It seems to be randomly solved by running audit2allow, but sometimes the audit.log cannot be parsed by audit2allow and then I am clueless as how to fix it :-/

# sealert -l f7a6d843-eb7c-498b-887f-d5b414b205d2
SELinux is preventing /usr/sbin/glusterfsd from write access on the sock_file .

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

If you believe that glusterfsd should be allowed write access on the  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
