Hello, Had some basic Ceph questions. a. Ceph is strongly consistent and different from usual object, does that mean all metadata also, container and account etc is all consistent and everything is updated in the path of the client operation itself, even for a single site? Is it the same for block and file?
b. If it is strongly consistent, is that the case across sites also? How can it be performant across geo sites if that is the case? If its choosing consistency over partitioning and availability...For block, I read somewhere that it is now eventually consistent(AP vs CP) via DR. Gets a bit confusing with all the literature out there. If it is DR, isnt that slightly different from the Swift case? c. For block, is it CP on a single site and then usual DR to another site using snapshotting? d. For block, is it just a linux block device or is it SCSI?
