Description of problem:
SELinux is preventing /usr/bin/bash from 'read' accesses on the file /usr/sbin/mdadm.

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

If you believe that bash should be allowed read access on the mdadm 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 sh /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
