Hello ml, I have been looking for an updated table like the one you can see here: https://ceph.com/geen-categorie/feature-set-mismatch-error-on-ceph-kernel-client/ Case in point we would like to use upmap on our ceph cluster (currently used mainly for CephFS) but `ceph feature` return: "client": [ { "features": "0x7010fb86aa42ada", "release": "jewel", "num": 69 }, ] despite the CephFS clients running with a fairly recent 4.15 kernel. If anyone has any pointers they would be most welcome Kind regards Mattia _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
