Description
Hi all,
I build a ceph cluster on a single host, with 1 mon, 3 osds. One osd created on a file path, two osds created on two hdd partion(1.8T, 1.9T) seperately.
Cluster health status is good, but rados df shows the total capacity is 30G.

Can any one figure out what may the problem be? Thanks in advance~

Can you show the message from "ceph osd df"?

the osd partitions are probably small. 'ceph osd df' and a regular 'df' on the osd host(s) will help.

Hi jianpeng, Sage,
Thanks for your attention. It seems that bluestore doesn't support paritioned block device nor directory use as osd. When I use a full disk as osd, everything works fine.
Is it designed so or it's a bug that when use bluestore only full disk can be used as osd?
