- I stand chastised. There are other reasons for doing it. I was assuming that
- if you knew enough to do performance tuning type stuff then you would
- ignore the post in instances where it was necessary. But there are a lot of
- people out there (even ones who can do the performance tuning) who seem to
- think that it's *necessary* to muck around with lvs in order to modify
- filesystems.
