[Spacewalk-list] WEB TRACEBACK At Startup

[Trung Tran]

Hi,

Every time I start Spacewalk, I got this message:

I followed some old posts and ran 'cobbler check' and got:

The following potential problems were detected:
#0: fencing tools were not found, and are required to use the (optional) 
power management features. install cman to use them

I'm a bit lost now.  How shoud I fix this?

Thanks.
