Or check whether such legacy data structures still exist in the mons? I'm not aware of an easy way to check the release a cluster started as. And unfortunately, there is no way to check for legacy data structures. If your cluster has used CephFS at all since Jewel, it's very unlikely there will be any in the mon stores. If you're not sure, best to upgrade through v15.2.14 to be safe. -- Patrick Donnelly, Ph.D. He / Him / His Principal Software Engineer Red Hat Sunnyvale, CA GPG: 19F28A586F808C2402351B93C3301A3E258DD79D _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
