Hi, Since firefly, ceph can support cache tiering. Cache tiering: support for creating ‘cache pools’ that store hot, recently accessed objects with automatic demotion of colder data to a base tier. Typically the cache pool is backed by faster storage devices like SSDs.
I'm testing cache tiering, and everything goes well. But rados -h shows that: CACHE POOLS: (for testing/development only) cache-flush <obj-name> flush cache pool object (blocking) cache-try-flush <obj-name> flush cache pool object (non-blocking) cache-evict <obj-name> evict cache pool object cache-flush-evict-all flush+evict all objects cache-try-flush-evict-all try-flush+evict all objects rados -v ceph version 0.80.7 (6c0127fcb58008793d3c8b62d925bc91963672a3) Is cache tiering production ready? Thanks a lot! _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
