David, Thank you. I have it currently as...
$ ceph osd df ID WEIGHT REWEIGHT SIZE USE AVAIL %USE VAR PGS 3 10.00000 1.00000 9313G 44404M 9270G 0.47 1.00 372 4 10.00000 1.00000 9313G 46933M 9268G 0.49 1.06 372 0 10.00000 1.00000 9313G 41283M 9273G 0.43 0.93 372 TOTAL 27941G 129G 27812G 0.46 MIN/MAX VAR: 0.93/1.06 STDDEV: 0.02 The above output shows size not as 10TB but as 9313G. So should I reweight each as 9.313? Or as the TiB value 9.09560?
