Description Dave Malcolm 2008-05-05 20:27:53 UTC
Description of problem:
Having moved a drive from another machine, got two VolGroup00, so have to rename
one of them; getting AVC denial at command line:
vgrename qcnIiE-Q8L5-dxgy-xIof-hzfj-SpjE-RnHr4m VolGroup01
  Renaming "/dev/VolGroup00" to "/dev/VolGroup00" failed: Permission denied

Summary
    SELinux is preventing /usr/sbin/lvm (lvm_t) "rename" to VolGroup00
    (device_t).

Detailed Description
    SELinux denied access requested by /usr/sbin/lvm. It is not expected that
    this access is required by /usr/sbin/lvm 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
    Sometimes labeling problems can cause SELinux denials.  You could try to
    restore the default system file context for VolGroup00, restorecon -v
    VolGroup00 If this does not work, there is currently no automatic way to
    allow this access. Instead,  you can generate a local policy module to allow
    this access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385
    Or you can disable SELinux protection altogether. Disabling SELinux
    protection is not recommended. Please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.

Could you upgrade machine to at least 5.1 or preferably 5.2 policy

udev/lvm fixes might also have fixed.
