Cool, thanks for the link :D The comment seems a little discouraging though: "Bcache looks like it's about ready for non critical use". That's about the same state as btrfs or zfsonlinux is currently in (both of which I use mostly for dev purposes btw). If you have more experience with bcache (whether good or bad) let us know. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
