Hello all, I have a few questions about Ceph: 1) Is it possible to run a cluster with "some" lantecy between monitor nodes? Latency will be 30ms at worst. 2) When using RBD what are the best practices for a direct mount using XFS filesystem? And for a qemu/kvm devices? I'm thinking about writeback, rbd_cache, ... 3) About the CRUSH map, how can I separate 2 pools on different OSD? I'd like to setup a cluster with different disks (like SATA/SAS) and I want to be able to specify on which disks (or OSD) my data are going to be write. Thanks in advance for any answer.
