Hello Ceph list! Is there a known problem with NFS4 ACLs and CephFS? After I have set the permissions with a Windows Samba client everything seems to be fine. But if I try: $getfattr -n security.NTACL -d /xyz /xyz: security.NTACL: No such attribute CephFS (Ceph 16.2.5) is mountet via the Ubuntu 20.04 kernel (5.4.0-80-generic). There was a problem in the past but it should be fixend in 5.4 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b8fe918b090442447d821b32b7dd6e17d5b5dfc1 Best, Alex _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
