DF Operation Reports File System as 100% Used (0% Free)

Symptom: Running the df command on a mounted file system unexpectedly reports zero available space (100% used, 0% free), rather than a realistic value.

Cause: The mount target that exports the file system has its Reported Size value set incorrectly.

Solution: Reset the mount target's Reported Size (GiB) to the default value of 8589934592 GiB. For instructions, see To set the file system reported size.
Important

Changing the Reported Size in the mount target affects all file systems exported through the mount target.
