Description Joe Christy 2010-08-05 15:08:43 UTC 
Summary:

SELinux is preventing /usr/sbin/smartd "mknod" access .

Detailed Description:

SELinux denied access requested by smartd. It is not expected that this access
is required by smartd 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.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Joe Christy 2010-08-05 15:25:55 UTC 
This seems to be a regression with my last yum update & reboot around 1900Z 2010-08-2.

This machine has a 3ware 9650SE RAID card.  I used to see selinux complain about the context of the /dev/twX devices that are necessary to see the individual discs in the array after a reboot, since F8, I can't recall when the problem was solved, alas.
Comment 2 Daniel Walsh 2010-08-05 18:42:40 UTC 

Miroslav can you add

	allow $1 self:capability mknod;

to storage_create_fixed_disk_dev

Then turning on smartmon_3ware boolean will give you this access.
