Getting "chmod: changing permissions of : Operation not permitted" error on nfs client where nfs share has been exported from AIX server

Solution Verified - Updated -

Issue

  • While trying to change permission getting below error :
chmod: changing permissions of : Operation not permitted
  • no_root_squash will not work in AIX.
  • The same filesystem is shared to other AIX clients where we can modify the files.
  • But on RHEL client we are facing the issue when I change the permissions of the files in the filesystem.

Environment

  • Red Hat Enterprise Linux(RHEL) 7
  • NFS Version 3
  • IBM AIX NFS Server
