Hi,
I think also it's much too complicate and the effort is not in any relation,
like Megor allready wrote the osd-journal
on SSD handle the speed.
But for the persistant device names you can easily use partlabel and select the
disk with something like
/dev/disk/by-partlabel/ext4-journal-15
I d
An interesting benchmark would be to compare "Ceph SSD journal" + "ext4 on
spinner" versus "Ceph without journal" + "ext4 on spinner with external SSD
journal".
I won't be surprised if the second outperformed the first - you are actually
making the whole setup much simpler and Ceph is mostly CPU

So you assume 3-way setup in Ceph: first drive for filesystem data, second
drive for filesystem journal and third drive for ceph journal?
