All,
I just came across a new package.
It is very young in its development, but it may have some basic functionality by summer and I would love to see it in OS 11.2.
It is a HSM (Hierarchical Storage Manager). http://code.google.com/p/fscops/
I'm not aware of a good GPL HSM in Linux currently.
With SSDs coming on strong, by the fall it would be great to have the ability to bring heavy i/o files up to SSD for processing, then push them back to rotating disk for less intense activity.

You can create a package of it and submit it to Contrib ;)

There are going to be patches to the kernel. And I don't think they can be implemented as a module. ie. the interface is pretty intrusive to the filesystem. I think they are looking at ext3 for their first effort.
Thus I assume Contrib is not really doable?

You should contact the kernel maintainers on opensuse-kernel ML. They can tell you more.

In fact, there is nothing like no-kernel-policy-in-contrib. But I don't think, that it's reasonable and kernel requests to Contrib will be rejected ;-)

Look at kernel-module-packages (KMPs), that might be an option how to do it - and kmps should be possible in contrib,

Yes, IMHO KMPs should be accepted in contrib unless they are backports of drivers already included in the official kernels.
However I think that patched kernels are a no go ;-)

Isn't that rather unlikely to be technically possile for a general HSM facility rather than a new filesystem type, if it's implemented in current File Systems, or the VFS layer then a module doesn't help.
What Greg Freemyer suggested, sounds rather similar to the generalised CacheFS, which is under consideration for mainline, if benchmarks can support it's effectiveness. There a fast SSD (or disk) can be used as 'backing' store, for slow disk or network filesystems.
Perhaps Greg Freemyer, could take a look Dave Howell's CacheFS, which should be fairly mature now?
