I am setting up a new disk on the same node to replace it. What is the best procedure to migrate data (or COPY ) from the failing OSD to the new one? Is there any stardard method to copy the OSD from one to another? best regards, samuel huxiaoyu@horebdata.cn _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io -- May the most significant bit of your life be positive.
