Re: [linux-lvm] How does LVM-Cache work?

Dne 26.2.2013 19:44, Leo Antonio napsal(a):
Hello, everyone.

I'm willing to do research about second-level cache using SSDs and I think
that the best way to do this is using LVM/Device Mapper, because other
implementations are based on FUSE, virtualization layers, and others.

What I'm trying to do is to develop a subsystem that will put hot blocks/PEs
on SSDs-Cache, as well as group related blocks/PEs on cache automatically. Not
simply put on SSD the most  used files or directories.

The problem is that I could not find any documentation about DM or LVM to help
my research and development.

Could you point me to some documentation or what's the best way to accomplish

Look for all-caches branch for dm-cache target:

My assumption is - it's most probably already developed and on its way for upstream inclusion.
