Thanks Sage,

Hi everyone.
I have 83 osds, and every osds have same 2TB, (Capacity sumary is 166TB)
I'm using replicate 3 for pools ('data','metadata').
But when mounting Ceph filesystem from somewhere (using: mount -t ceph
Monitor_IP:/ /ceph -o name=admin,secret=xxxxxxxxxx")
then capacity sumary is showed "160TB"?, I used replicate 3 and I think
that
it must return 160TB/3=50TB?
Filesystem Size Used Avail Use% Mounted on
192.168.32.90:/ 160T 500G 156T 1% /tmp/ceph_mount
Please, explain this help me?
statfs/df show the raw capacity of the cluster, not the usable capacity.
How much data you can store is a (potentially) complex function of your
CRUSH rules and replication layout. If you store 1TB, you'll notice the
available space will go down by about 2TB (if you're using the default
2x).
