Technically correct, but I am guessing the OP is thinking of an actual pool of SSD's, rather than a Ceph pool. So to give a slightly different answer, no 1 cache pool can't tier multiple base pools. But multiple cache pools could be created on the same set of SSD's to accomplish this, keeping in mind available space. > > > > > Documentation only takes example with a single backend pool, or I > > didn't find the information. > > > > Thank you. > > > > Florent > > _______________________________________________ > > ceph-users mailing list > > ceph-users@lists.ceph.com > > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > _______________________________________________ > ceph-users mailing list > ceph-users@lists.ceph.com > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
