Description Jake Jackson 2015-12-01 18:17:45 UTC
Description of problem:
My RAID1 suddenly disappeared. A restart didn't resolve the issue. So i ran
$ sudo mdadm --assemble --scan
and this alert went off.
SELinux is preventing mdadm from 'search' accesses on the directory /sys/firmware/efi/efivars.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
/sys/firmware/efi/efivars default label should be sysfs_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /sys/firmware/efi/efivars

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that mdadm should be allowed search access on the efivars 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:
# grep mdadm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
