I would love to see this, but it might be good to look at all the LVM
software available and decide what we want just to make sure no good
features are left out. Also, I believe that there was a group of
people working on a logging file system for linux and I think they were
keeping the idea of resizing the file system in mind. I don't remember
the URL for the project web page though.

I have never used the IRIX volume management software, but I do use the
Digital Unix advfs file system, and I like it a lot. I found the man
page for advfs on line at:

http://www.rz.uni-wuerzburg.de:5000/advfs(4)

I know that Sun and IBM have similar software, but I don't have any
information on those either. Perhaps someone else will.

Thanks again for bringin this up.

Jim
