Thanks to all for responses. Great thread with a lot of info.
I will go with the 3 partitions on Kingstone SDD for 3 OSDs on each node.
Thanks

Hi,
I have also posted on the OpenNebula community forum

Does anyone have any experience of changing the monitors in their Ceph cluster

Hi,
With 5 hosts, I could successfully create pools with k=4 and m=1, with the
failure domain being set to "host".
With 6 hosts, I could also create k=4,m=1 EC pools.
But I suddenly failed with 6 hosts k=5 and m=1, or k=4,m=2 : the PGs were never
created - I reused the pool name for my tests, th

Hi,
looking at the outputs below the following puzzles me:
You have two nodes but repl.size 3 for your test-data pool. With the

So either change to rep.size 2, or add another node ;-)

Hi all,
In the original paper (RADOS: a scalable, reliable storage service for

(primary copy, chain and splay).
Now the documentation only discusses primary copy. Does the chain scheme
still exist?
It would be much more ba

Generally speaking, it is going to be super difficult to maximize the

don't think Ceph is aiming at high performance storage.
