I would like to second this question, as I wasn't able to find anything in the documentation so far. did you just alter the ceph osd service files to taskset the osd process to specific nodes or are there configuration switches, which I didn't yet find, to tell ceph how many cores per OSD should be used? -- Mit freundlichen Grüßen / Regards Sven Kieske Systementwickler / systems engineer Mittwald CM Service GmbH & Co.
