Yoann Moulin <yoann.moulin(a)epfl.ch> ==> ceph-users(a)ceph.io :
Is it better to put all WAL on one SSD and all DBs on
the other one? Or put WAL and DB of the first 5 OSDs on the first SSD and the 5 others on
the second one.
I don't know if this has a relevant impact on the latency/speed of the ceph system but
we use LVM on top of a SW RAID 1 over two SSDs for WAL & DB on this RAID1.
Cheers,
Lars
