Copying via NFS - file permissions

Post by pkf » Sun Jul 22, 2018 6:55 am

I copy files from linux to qnap via NFS. Can I copy them in such way that the copied files would be accessible by qnap users who have access to certain shared folder? Now it doesn't work, looks like I have to manually change the files permissions after copying. Thank you.

Well, welcome to NFS. U*x mask, users (sid), group (gid), ACLs, ... it's all under the full control of the NFS client, where you mount the stuff. Consider to migrate towards using SMB instead of NFS mounts.

As long as each user's UID number is the same on the linux machine and the QNAP, it should be easy.
Then it can be done using cp -p (Preserve)
