Description of problem:i get all zeros with sar -d and mostly zeros with sar -b Version-Release number of selected component (if applicable):sysstat-5.0.1-2 How reproducible:always Steps to Reproduce: 1. sar -bd 2. see lots of zeros 3. Actual results:bunch of zeros Expected results:valid stats Additional info:i'm using lvm
The manpage states that sar -b only reports valid data on kernels older than 2.5. FC2 has a 2.6 kernel so no stats will be produced. On a personal system it is normal to see low values or zeros for stats on most of your devices most of the time.
