df command cannot report accurate size and capacity
Details: If you run the df command on a filesystem in an NFS
client, df reports a filesystem size of 0 (zero) bytes and a capacity
of 8 EB (maximum capacity). Because Object Storage does
not have quotas and can store an unlimited amount of data, there is not a way to report
filesystem size. Because the Object Storage bucket does
not report storage usage, there is not a way to report capacity.
Workaround: You can run the du command to get usage, however this
command is metadata intensive and takes longer to report usage. You could also list all
objects in Object Storage and add the object size to
determine current Object Storage usage. However, this
method doesn’t take into account the amount of data stored in the filesystem cache. You
can also explore out‑of‑band mechanisms that approximate storage usage.
