Hello, I've a cluster of 35 OSD (30 HDD, 5 SSD) with cache tiering configured. During tests it looks like ceph is not respecting target_max_bytes settings. Steps to reproduce: - configure cache tiering - set target_max_bytes to 32G (on hot pool) - write more than 32G of data - nothing happens
If I set target_max_bytes again (to the same value or any other option, for example cache_min_evict_age) ceph will start to move data from hot to base pool. I'm using ceph in version 0.80.4 (with cherry-picked patch from bug http://tracker.ceph.com/issues/8982. Is there away to make it work as expected? -- PS _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
