Quotas are very important to Samba (and Windows) admins. See e.g. http://www.samba.org/samba/docs/man/manpages-3/smbcquotas.1.html But I would defer to Metze and others on the server side to see whether XFS or the proposed ext4 quotas match the protocol requirements which Samba has to support. Does anyone know whether Samba can handle all of the remote quota admin operations on Linux/XFS today (and local enforcement)? --=20 Thanks, Steve -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
