We use shared directories for projects in our hpc cluster and use acls to achieve this. https://www.redhat.com/sysadmin/linux-access-control-lists -- Paul Mezzanini Platform Engineer III Research Computing Rochester Institute of Technology Sent from my phone, please excuse typos and brevity ________________________________ From: duluxoz <duluxoz@xxxxxxxxx> Sent: Thursday, May 9, 2024 2:03:02 AM To: ceph-users@xxxxxxx <ceph-users@xxxxxxx> Subject: Forcing Posix Permissions On New CephFS Files 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 Dulux-Oz _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
