The only real issue I can see is with linear volumes, but those are stupid anyway - non of the gains but all the risks.Linear volumes may well be the most common ones. People start out with the filesystems at a certain size, increasing onto a second (new) disk later, when more space is required.Are they aware of how risky linear volumes are? I would discourage anyone from using them.
In what way are they risky? Cheers, Dave. -- Dave Chinner david@fromorbit.com
