I was looking into some custom fileserver options and noticed two facts about ZFS - support for L2ARC (albeit not persistant across reboots, which is a downer) and OpenSolaris being a dead meat. Then I found out that some patches were already floating around linux mailinglists, patches about hot data relocation, but unfortunately nothing definitive. So I would like to ask here: what is the status of hot data relocation functionality? I haven't had a chance to try out btrfs myself, but from what I see it sure looks promising and seems like an option worth waiting on (I mean this from fileserver with SSD cache point of view). So keep up the good work, and thanks for an answer, if there will be one :) Take care, b.
