Hello List,
i have 3 Node with size = 2 and min_size = 2 (i will change it to
size=3). Connected via 10GBit. IPerf shows about 8.8GBit/sec.
I just want to make sure everthing is okay until here. ( since i have
a rbd benchmark problem )
The Nodes have HDDs (spinning rust) and here is "ceph tell os
Hello,
is there a difference between those two benchmarks?

Hohoho Merry Christmas and Hello,
i set up a "poor man´s" ceph cluster with 3 Nodes, one switch and
normal standard HDDs.
My problem; with rbd benchmark i get 190MB/sec write, but only
45MB/sec read speed.
Here is the Setup: https://i.ibb.co/QdYkBYG/ceph.jpg
