Hi all, The release notes are missing an upgrade step that is needed only for clusters *not* managed by cephadm. This was noticed in https://lists.ceph.io/hyperkitty/list/ceph-users@xxxxxxx/thread/7KSPSUE4VO274H5XQYNFCT7HKWT75BCY/ If you are not using cephadm, you must disable FSMap sanity checks *before starting the upgrade*: ceph config set mon mon_mds_skip_sanity 1 After the upgrade is finished and the cluster is stable, please remove that setting: ceph config rm mon mon_mds_skip_sanity Clusters upgraded by cephadm take care of this step automatically.
