Description Richard Shaw 2011-01-26 12:56:15 UTC
SELinux is preventing /usr/sbin/smartd from 'ioctl' accesses on the blk_file /dev/sdc.

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

If you want to fix the label. 
/dev/sdc default label should be fixed_disk_device_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /dev/sdc

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

If you believe that smartd should be allowed ioctl access on the sdc 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 smartd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comments:

I tried restoring context on /dev/sdc in case that's what was wrong but it didn't seem to help.

Comment 1 Richard Shaw 2011-01-26 12:57:38 UTC
Also just noticed the first setroubleshoot error that looks to be related:


SELinux is preventing /usr/sbin/smartd from 'read' accesses on the blk_file sdc.
