Does QFS run in addition to other file systems on the storage nodes or does it manage disks directly? You see, I was thinking that maybe ZFS + QFS might be a good idea and would like to know if it's possible. Also, is QFS available for FreeBSD and/or SmartOS storage nodes and clients? How about CoreOS and Debian, are storage nodes and clients available for those?
