Hi all! I got quite far till now, and I documented my progress here:

I'd like to set up new OSDs with bluestore: the real data ("block") on a spinning disk, and DB+WAL on a SSD partition. But I do not use ceph-deploy, and never used ceph-disk (I set up the filestore OSDs manually). Google tells me that ceph-disk does not (yet) support splitting the components across multiple block devices, I also had no luck while attempting it anyways. (using Ceph 12.1 RC1) I just can't find documentation on how to set up a bluestore OSD manually: * How do I "prepare" the block, block.wal and block.db blockdevices? Just directing ceph-osd to the block devices via ceph.conf does not seem to be enough. * Do bluestore OSDs still use/need a separate journal file/device? Or ist that replaced by the WAL? http://docs.ceph.com/docs/master/ also has not very much information on using bluestore, is this documentation deprecated? Thanks for any hints, Martin
