I used to use rsync to copy files after nfs mount.

When I tried it in a new RHEL server , I got the error message
rsysnc chown .... failed. Invalid argument (22)

Can anybody help me

Are you copying from RHEL to Windows?

Make sure both target and destination is using file system that supports chown, or ext# file system.

or just do an rsync -av <your parameters source - destination>

or post the rsync command you supplied.

Sorry for the delay in reply. I was not in station for few days.
I am copying files from Linux to Linux
Command is
rsync -azv --delete source destination

works fine for me. Can you copy the actual command plus error message and paste here as a quote?

Regards

The invalid argument (22) message more-or-less happens with any connectivity issue. It is trying to set the ownership of the transferred file. Unfortunately, rsync is not the world's best at producing meaningful error messages.

Provide us with the actual rsync command that you are trying to use, and tell us a little bit more about that share ... and your permissions to it.

Remember that NFS is very peculiar with regards to owner-ids. Does this owner-id (uuid number ...) exist on both servers? Does the share allow you to change it, or does it "squash?"
