Yes, reads are served from primary OSDs.. Adding OSD nodes should definitely increase your performance, but, you need to see first whether you are getting the desired performance (or maxed out) with
the existing cluster or not. Please give some more information about your cluster and let us know what IOPs are you getting for what block size ? Thanks & Regards Somnath From: ceph-users [mailto:ceph-users-bounces@xxxxxxxxxxxxxx]
On Behalf Of Le Quang Long Hello, I'm having a concern about CEPH Read IOPS. I'm not sure how Ceph settles Read request: - Whether only primary OSD or all replica OSDs reply read requests ? - Do I increase Read IOPS by supplementing OSD nodes to cluster? If not, is there any method to do? Thanks and regards. PLEASE NOTE: The information contained in this electronic mail message is intended only for the use of the designated recipient(s) named above.
