I do most of our testing using the command line parameters as well. >What version of fio are you using? Maybe there is a bug.

Installed on Ubuntu 13.04 from the default repositories (just did an 'apt-get install fio'). _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
