Description of problem:
SELinux is preventing mdadm from 'read' accesses on the directory dma_heap.

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

If you believe that mdadm should be allowed read access on the dma_heap directory 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:
# ausearch -c 'mdadm' --raw | audit2allow -M my-mdadm
# semodule -X 300 -i my-mdadm.pp
