Hello I am setting up a new ceph cluster (probably Mimic) made up of servers that have a mixture of solid state and spinning disks. I'd like CephFS to store data of some of our applications only on SSDs, and store data of other applications only on HDDs.
Is there a way of doing this without running multiple filesystems within the same cluster? (E.g. something like configuring CephFS to store data of some directory trees in an SSD pool, and storing others in an HDD pool) If not, can anybody comment on their experience running multiple file systems in a single cluster? Are there any known issues (I am only aware of some issues related to security)? Does anybody know if support/testing of multiple filesystems in a cluster is something actively being worked on and if it might stop being "experimental" in near future? Thanks very much, Vlad _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
