Hi Christoph, No. Splitting data and distributing it across multiple OSDs without generating parity chunks is not possible in Ceph (k=2,m=0 with erasure coding wouldn't make sens). Either you use replication or erasure coding with at least a coding chunck (m>=1). Regards, Frédéric. ----- Le 18 Nov 24, à 17:13, Christoph Pleger Christoph.Pleger@cs.tu-dortmund.de a écrit :
Hello,
Is it possible to have something like RAID0 with Ceph?
That is, when the cluster configuration file contains
osd pool default size = 4
and I have four hosts with one osd drive (all the same size, let's call it size s) per host, is it somehow possible to add four other hosts with one osd drive (again with size s) per host, so that the resulting Ceph block device is of size 2 * s?
Regards Christoph
