Hi, If you do not have a CephFS filesystem that was created with a Ceph version older than Firefly, then you can ignore this message. If you have such a filesystem, you need to run a special command at some point while you are using Jewel, but before upgrading to future versions. Please see the documentation here: http://docs.ceph.com/docs/jewel/cephfs/upgrading/ In Kraken, we are removing all the code that handled legacy TMAP objects, so this is something you need to take care of during the Jewel lifetime. Thanks, John _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
