Ceph » CephFS

When using ceph-fuse to mount the cephfs file directory, if there are multiple data pools built in FS, the capacity of all OSDs is displayed. If there is only one data pool in FS, it displays the correct capacity information.

Can be constructed as follows:

[root@hw110 tecs]# ceph df
