+ 1 disk "boot" (ext4)
1 disk has RAID with btrfs.
SELinux is preventing mdadm from 'read' accesses on the dossier dma_heap.

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

Si vous pensez que mdadm devrait être autorisé à accéder read sur dma_heap directory par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
autoriser cet accès pour le moment en exécutant :
# ausearch -c "mdadm" --raw | audit2allow -M my-mdadm
# semodule -X 300 -i my-mdadm.pp
