Reinstall the nodes one by one (with new OS) As long as the software version is the same (or at least, same major release), and your mons maintain quorum, you should be fine - we migrated from Ubuntu CEPH packages to croit.io's solution, one OSD node at a time, and it went very smoothly. You would probably want to add the extra mons first, then retire the old ones, in a rolling fashion. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
