Linux appears cp:preserving permissions for ' filename ': Operation not supported error and resolution __linux

Problem:

The following error always occurs when using the CP and MV commands on Linux today to manipulate files on NFS

cp:preserving permissions for ' filename ': Operation not supported

Reason:

This error is due to the support of the CP and MV commands for ACLs, the MV command maintains ACL settings information, and the CP command retains ACL settings when using the-p,-a parameter. However, if you move from an ACL-enabled file system to a file system that does not support ACLs or a copy of an ACL attribute, you get an error like the following

cp:preserving permissions for ' filename ': Operation not supported

Files that have ACLs set on Ls-l can be seen in this case,

-RW-RW----+ 1 Allen Chen 0 June 2 09:52 filename

There is a plus sign at the end of the first column.

Solution:

Modify the/etc/fstab file to specify ACL options for the file system to mount, as follows:

<HOST>:/DATA/EXPORT/PCC       /PCC        NFS
