[ceph-users] How to move OSD form 1TB disk to 2TB disk

I know another way: out 1TB osd, up 2TB osd as osd.X without data, then rados will backfill the data to 2TB disks. Now I use rsync to mv data form 1TB disk to 2TB disk, but the new osd coredump. What's the problem? ceph version:0.80.1 osd.X host1 with 1TB disks host2 with 2TB disks on host1:

-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 You will want size=4 min_size=2 if you want to keep I/O going if a DC fails and ensure some data integrity. Data checksumming (I think is being added) would provide much stronger data integrity checking in a two copy situation as you would be able
