I'd like to build a cluster for storing large amounts of data.
The cluster would consist of slow (cheap) storage and fast (expensive)

I would like to migrate data from fast (expensive) storage to slow (cheap)
storage if it wasn't accessed for, say, 6 months.
Would ceph somehow help me achieve that?
We don't currently have that functionality. In principle it's certainly
something the system could do, and the underlying storage architecture
lends itself to that:
Hmm, since quite recently, Linux kernel has FS-Cache, which:
This facility is a general purpose cache for network
filesystems, though it could be used for caching other things
such as ISO9660 filesystems too.
I wonder if it could work with ceph and/or traditional filesystems, too?
