I stayed away from LVM so I could run XFS without worrying. Used an old 600Mhz box and a hardware RAID controller, and mounted it with nfs. Can replace the controller if it fails, replace a drive that fails, and expand the array on line. Maybe I am deluding myself because I do not understand all the details of LVM and the potential for XFS to corrupt, but I have been more than happy with this setup and it is in heavy usage.
When they get on-line expansion working for adding devices (as I learned they are working on above) for software RAID, I think that would be my preference (most recoverable and cheapest). _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
