I tried it on a mini-cluster (4 Raspberries) with 16.2.7. Same procedure, same effect. I just can’t get rid of these objects. Is there any method that would allow me to delete these objects without damaging RGW?

I believe this issue may have beenn fixed as part of [1], backported to v16.2.7 [2]. Maybe you could try upgrading your cluster and recheck. > > > Thanks, > > Soumya > > > [1] https://tracker.ceph.com/issues/53222 > > [2] https://tracker.ceph.com/issues/53291 > > > > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
