How to change files ownership in mount point

Currently, I have two mount points which mount to the same hard drive at start up as follows:

mount -F /.../draw/draw

mount -F /.../scan/scan

Draw slice stored drawings which have "drafter"(owner) and "draftergr"(group) in file names.

Scan slice stored drawings which have "nobody" (owner) and "nogroup" in file names.

I want to move (log on as "drafter") all drawings from scan to draw but the error appears : permission denied or not owner of the file.

I can not change the file owner from nobody to drafter in mount point either.

Would you suggest a solution to me , I appreciate for your help.

Thanks in advance.

Why not? What is the error you're getting when you try doing this ?

At first I think this to be a permission related problem. When files aren't owned by your uid or group and you have no write permissions you're usually also not allowed to move them.

Look into chmod or perhaps chown is what I'd advice.

Hi Lion_O ,

Thanks for your message. I need to clarify that the SCAN mount point stored those drawings come from a scanner. The former Unix admin set up ownership of all files to Nobody (user) and Nogroup (group).

I can log on as Root ( I am a current admin) to change chown or chmod on any files except those drawings.

Can I modify the mount command such as

mount -F -o users /.../SCAN/SCAN

mount -F -o users /.../DRAW/DRAW

so that I can move those files from SCAN to DRAW.

Thanks for your suggestions.

Once again; what is the error message you're getting? And in addition; is all of this happening on an UFS filesystem ?

Because if you're using ufs then the 'users' extra option is likely not to do anything (check the mount(1M) and mount_ufs(1M) manualpages).
