The following was filed automatically by setroubleshoot: Résumé: SELinux is preventing mdadm "read" access on .mdadm.map. Description détaillée: [mdadm has a permissive type (mdadm_t). This access was not denied.] SELinux denied access requested by mdadm. It is not expected that this access is required by mdadm and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Autoriser l'accès: You can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

For some reason a file .mdadm.map was created under /dev.
Doug, Any reason this file is created in /dev rather then under /var/run/mdadm? Is this file being created by mdadm?
Yes, /var/run/mdadm is often times read only when we are doing the initial incremental assembly of arrays. If mdadm can not create its map file, then it doesn't do incremental assembly properly. The map file was moved to /dev because it is always read/write by the time we are doing incremental assembly and therefore solves the issue.
Fixed in selinux-policy-3.6.31-2.fc12.noarch /dev/.mdadm.map -- gen_context(system_u:object_r:mdadm_map_t,s0)
