At this point, FD 4 is the source file (./test.sh) and FD 5 is the destination file (/tmp/test.sh). > $ mount | grep patrice > /home/patrice type nfs4 > (rw,nosuid,nodev,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=X,local_lock=none,addr=Y) Looks like the error happens while trying to set the extended attributes on the destination file. I don't really know how xattr works, but it looks like it's trying to set an attribute named "system.nfs4_acl" on a file that's in the /tmp directory. I can't tell whether this is a bug in cp, or a bug in the kernel. Someone who understands xattr might be better able to help. > Finally, note that I am a «he» otherwise in French it's generally Patricia for > «her» > :-D My apologies. Patrice is a feminine name in English.
