I can set quotas on any sub-directory. Is this intentional? The documentation (https://docs.ceph.com/en/octopus/cephfs/quota/#quotas) says > > > CephFS allows quotas to be set on any directory in the system. > > Any includes the fs root. Is the documentation incorrect or is this a bug? I'm not immediately seeing why we can't set quota on the root, but the root inode is special in a lot of ways so this doesn't surprise me. I'd probably regard it as a docs bug. That said, there's also a good chance that the setfattr is getting intercepted before Ceph ever sees it, since by setting it on the root you're necessarily interacting with a mount point in Linux and those can also be finicky...You could see if it works by using cephfs-shell. -Greg > > Best regards, > ================= > Frank Schilder > AIT Risø Campus > Bygning 109, rum S14 > _______________________________________________ > 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
