For testing if "production ready" i'm implementing Multiple-User Time-Machine Backup with samba 4.8.0rc4 and zfsonlinux v0.7.6 and it's looking promising so far. Taking a closer look, i see quite high smbd cpu load on initial time machine run and with that, a lot of Metadata lookup misses, even after setting xattr=sa and dnodesize=auto in zfs (as recommended, see below excerpt from zfs manpage) furthermore, even with "log level = 0" i'm getting tons of entries in log.smbd, which seem to relate to time-machine. Maybe someone with deeper knowledge wants to have a look to judge if this is normal/expected behaviour or not. for me it looks very weird and i also wonder about the high smbd load. maybe it's because samba has tom maintain a lot of locked files, as timemachine sparsebundle image conists of multiple "bands" files from which many are opened and locked in parallel ?

The default value is legacy. Setting this property to a value other than legacy requires the large_dnode pool feature to be enabled. Consider setting dnodesize to auto if the dataset uses the xattr=sa property setting and the workload makes heavy use of extended attributes. This may be applicable to SELinux-enabled systems, Lustre servers, and Samba servers, for example. Literal values are supported for cases where the optimal size is known in advance and for performance testing. xattr=on|off|sa Controls whether extended attributes are enabled for this file system. Two styles of extended attributes are supported either directory based or system attribute based. The default value of on enables directory based extended attributes. This style of extended attribute imposes no practical limit on either the size or number of attributes which can be set on a file. Although under Linux the getxattr(2) and setxattr(2) system calls limit the maximum size to 64K. This is the most compatible style of extended attribute and is supported by all OpenZFS implementations. System attribute based xattrs can be enabled by setting the value to sa. The key advantage of this type of xattr is improved performance. Storing extended attributes as system attributes significantly decreases the amount of disk IO required. Up to 64K of data may be stored per-file in the space reserved for system attributes. If there is not enough space available for an extended attribute then it will be automatically written as a directory based xattr. System attribute based extended attributes are not accessible on platforms which do not support the xattr=sa feature. The use of system attribute based xattrs is strongly encouraged for users of SELinux or posix ACLs. Both of these features heavily rely of extended attributes and benefit significantly from the reduced access time The values on and off are equivalent to the xattr and noxattr mount options.
