[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
