Welcome to StashFS
This is a current work of progress. As such, I'll post a few things, on here, but it may not be updated frequently or at all useful. Realistically there needs to be some other development work done as an underpinning to make this practical for use. Once that is in place, then I'll be taking another look at this and investigating ways to make this make more sense.
I have a reasonable prototype of this system. It will hopefully be posted up in the next few days. I'll be using it and working out some more of the bugs that end up coming up and seeing if I can work out some more features into it, such as readahead, etc. Some information on how to use it will also be posted with a copy of the source being realesed under a reasonable license.
Writeup (May 11th). Here is a realtively stable version of the stashfs writeup. This was submitted as part of my Senior Honors Thesis.
