Hi all, I was wondering what happens when reads are issued to an RBD device with no previously written data. Can somebody explain how such requests flow from rbd (client) into OSDs and whether any of these reads would hit the disks at all or whether OSD metadata would recognize that there is no data at the offsets requested and returns a bunch of zeros back to the client?
