Hi Emmanuel, regarding stopping state. We had a similar issue. see subject: MDS Upgrade from 17.2.5 to 17.2.6 not possible We solved this by failing the MDS, which was in the stop state, but I don't know if that's a good idea in general. What does the log of the mds (stopping) shows? We observed "waiting for strays to migrate" Best, Henning _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
