/aha directory is full

E2E alert analysis report shows

File system used (%): File system =/aha is like the image below.

After further investigation we could not understand the reason as there are several directories that were created by ahafs directly and seems to be 0 byte in size. We do df -g (AIX system), but it shows only - for disk space. Kindly ask you to clarify the /ahafs mount procedure and how to look inside /ahafs. How to resolve this problem?

Thanks in advance!
