 |
|
Hi,
I have a NFS export mounted on two Gentoo machines. Copying a file from the export one Machine 1 fails with the following:
| Code: | cp -fpPRH "/mnt/buildsupport/downloads/imx-gpu-viv-6.4.3.p4.6-aarch64.bin" "."
cp: preserving permissions for ‘./imx-gpu-viv-6.4.3.p4.6-aarch64.bin’: Operation not supported

Where is "." located, what file system is it, and does it support permissions?

Its an ext4 partition on both Machine 1 and Machine 2.
After the cp command fails the file does exist and if I execute the following command it completes with no error.
| Code: | | cp -fpPRH "imx-gpu-viv-6.4.3.p4.6-aarch64.bin" "imx-gpu-viv-6.4.3.p4.6-aarch64.bin.2" |
