Dear Cepher, On a Ceph node (Luminous 12.2.13), i had a HDD with smartctl inidicating going to fail soon but still operational, and i would like to replace it now. It is no fun to rebalance the data and then get a new disk in and do rebalanance again. I am thinging of using ceph-objectstore-tool to copy the data from the failing HDD to a new HDD on the same ceph node, with the same OSD ID. Is it possible, and how? thanks in advance for advice, samuel huxiaoyu@horebdata.cn
