[SOLVED] One PC has NFS shares being mounted with system.nfs4_acl= attribute. Others do not.

I am sure that this is a local issue, but I am hoping that other eyes might help.
In a small local LAN, on one PC, when an NFS share is mounted then files are being with a system.nfs4_acl= attribute.

Code:

# getfattr -d -m "-" /mnt/tmp/root/unmanaged.sh 
getfattr: Removing leading '/' from absolute path names
# file: mnt/tmp/root/unmanaged.sh
system.nfs4_acl=0sAAAAAwAAAAAAAAAAABYBpwAAAAZPV05FUkAAAAAAAAAAAAAAABIAoQAAAAZHUk9VUEAAAAAAAAAAAAAAABIAoQAAAAlFVkVSWU9ORUAAAAA=

No such attribute appears when mounting NFS shares on the other PCs. All are running Slackware64-15.0 and get updates in unison.

This is not a show stopper, but leads to error messages like

Quote:

cp: preserving permissions for ‘<filename>’: Operation not supported

when running 'cp -av' that I would like to go away.

Somehow I have flicked something, but so far I cannot find the cause. Any ideas?

Do you see any difference for that mountpoint in /proc/mounts when comparing between your NFS clients?

Thanks for the interest. I think you have hit on something.
From the output of 'cat /proc/self/mounts' on Eagle, the PC that is seeing the setting of the attribute.

From the output of 'cat /proc/self/mounts' on Magpie, a PC that is NOT seeing the setting of the attribute.

Any idea what is causing the setting of nfs4 vers=4.2 when the share is mounted on Eagle?

[/EDIT]Never mind. Found it. Eagle was missing the /etc/nfsmount.conf file. Thanks again Henrik[/EDIT]
