Description Ian Pilcher 2013-09-23 16:13:28 UTC
Description of problem:
I get this denial every time I shutdown a VM that uses logical volumes as virtual disks.
SELinux is preventing /usr/sbin/mdadm from 'read' accesses on the blk_file dm-12.

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

If you believe that mdadm should be allowed read access on the dm-12 blk_file 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
