How to the Root user of OS to change ownership of sub-directory created by root user of that OS (OS is Linux and mounted via NFS protocol of HNAS)? Because when I try to change it, but it can’t to change.
I understand what's wrong about the permission of HNAS system.
Please help guide to me to the concept about how to give the permission of File systems.
Example to try
- HNAS : NFS export of HNAS = “/nfstest1”
- Root OS : mount -t nfs xx.xx.xx.xx:/nfstest1 /mnt/nfstest1
- HNAS : Mapping UID = user, GID = user -> 10001 = user1, 10001 = user1
- HNAS : add option at "Access Configuration" -> 0.0.0.0 (rw, norootsquash)
- Root OS : "chown user1.user1 /nfstest1" or "chgrp user1 /nfstest1" (change perrmission from Root user)
- Root OS : ls -la /nfstest1 (as below figure)
- HNAS : ls -la /nfstest1 (but on HNAS do not change but it auto force change that path NFS export is 65534)
