Hello Matthew, You can inherit the group, but not the user, of the containing folder. This can be achieved by making the folder setgid and then making sure that the client systems have a proper umask. See the attached PDF for a presentation that I conducted on this topic to my students in the past. On Thu, May 9, 2024 at 2:03 PM duluxoz <duluxoz@gmail.com> wrote:
Hi All,
I've gone and gotten myself into a "can't see the forest for the trees" state, so I'm hoping someone can take pity on me and answer a really dumb Q.
So I've got a CephFS system happily bubbling along and a bunch of (linux) workstations connected to a number of common shares/folders. To take a single one of these folders as an example ("music") the sub-folders and files of that share all belong to root:music with permissions of 2770 (folders) and 0660 (files). The "music" folder is then connected to (as per the Ceph Doco: mount.ceph) via each workstation's fstab file - all good, all working, everyone's happy.
What I'm trying to achieve is that when a new piece of music (a file) is uploaded to the Ceph Cluster the file inherits the music share's default ownership (root:music) and permissions (0660). What is happening at the moment is I'm getting permissions of 644 (and 755 for new folders).
I've been looking for a way to do what I want but, as I said, I've gone and gotten myself thoroughly mixed-up.
Could someone please point me in the right direction on how to achieve what I'm after - thanks
Cheers
