I understand this needs to be purchased from Red Hat in order to get access to it if you are using the Red Hat subscription management system. I expect you could drag over the CentOS RPM but you would then need to track updates/patches yourself (or minimally reconcile differences between Red Hat and CentOS). In summary: XFS on Red Hat is a paid-for-option. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
