Description Danie de Jager 2015-10-22 09:44:39 UTC
Description of problem:
SELinux is preventing df from 'getattr' accesses on the blk_file /dev/dm-3.

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

If you believe that df should be allowed getattr access on the dm-3 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 df /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
