Description of problem:
SELinux is preventing /usr/bin/ksysguardd from 'read' accesses on the file mdstat.

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

If cree que de manera predeterminada, ksysguardd debería permitir acceso read sobre  mdstat file.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso momentáneamente executando:
# grep ksysguardd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
