Currently, I have 3 OSDs in 3 different hosts:
# ceph osd tree:
ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF
-1 0.03908 root default
-3 0.00980 host node1
0 hdd 0.00980 osd.0 up 1.00000 1.00000
-9 0 host node2
-5 0.00980 host node3
1 hdd 0.00980 osd.1 up 1.00000 1.00000
-7 0.01949 host node4
2 hdd 0.01949 osd.2 up 1.00000 1.00000
When I insert data into the pool, the data is equally distributed on 3 OSDs. (3 replicas)
However, I want the osd.2 to hold more data since it has more space.
What additional data should OSD 2 hold?
The pool has a size of 3, i.e. all data objects have three copies.
The cluster only has 3 OSDs, so each OSD gets one copy.
In this configuration your available capacity is that of the smallest
OSD. You cannot use additional space in larger OSDs.
Such a heterogenous setup is only possible with a large number of OSDs
where the placement groups can be assigned more flexible to the OSDs.
