Add more details to the description of the fsid_guid dataset property
6333 ZFS should let the user specify or modify the fsid_guid of a dataset


 575        this property at file system creation time by using the -o copies=N
 576        option.
 577 
 578      devices=on|off
 579        Controls whether device nodes can be opened on this file system. The
 580        default value is on.
 581 
 582      exec=on|off
 583        Controls whether processes can be executed from within this file
 584        system. The default value is on.
 585 
 586      filesystem_limit=count|none
 587        Limits the number of filesystems and volumes that can exist under this
 588        point in the dataset tree. The limit is not enforced if the user is
 589        allowed to change the limit. Setting a filesystem_limit to on a
 590        descendent of a filesystem that already has a filesystem_limit does not
 591        override the ancestor's filesystem_limit, but rather imposes an
 592        additional limit. This feature must be enabled to be used (see
 593        zpool-features(5)).
 594 









 595      mountpoint=path|none|legacy
 596        Controls the mount point used for this file system. See the Mount
 597        Points section for more information on how this property is used.
 598 
 599        When the mountpoint property is changed for a file system, the file
 600        system and any children that inherit the mount point are unmounted. If
 601        the new value is legacy, then they remain unmounted. Otherwise, they
 602        are automatically remounted in the new location if the property was
 603        previously legacy or none, or if they were mounted before the property
 604        was changed. In addition, any shared file systems are unshared and
 605        shared in the new location.
 606 
 607      nbmand=on|off
 608        Controls whether the file system should be mounted with nbmand (Non
 609        Blocking mandatory locks).  This is used for SMB clients. Changes to
 610        this property only take effect when the file system is umounted and
 611        remounted. See mount(1M) for more information on nbmand mounts.
 612 
 613      primarycache=all|none|metadata
 614        Controls what is cached in the primary cache (ARC).  If this property

 576        option.
 577 
 578      devices=on|off
 579        Controls whether device nodes can be opened on this file system. The
 580        default value is on.
 581 
 582      exec=on|off
 583        Controls whether processes can be executed from within this file
 584        system. The default value is on.
 585 
 586      filesystem_limit=count|none
 587        Limits the number of filesystems and volumes that can exist under this
 588        point in the dataset tree. The limit is not enforced if the user is
 589        allowed to change the limit. Setting a filesystem_limit to on a
 590        descendent of a filesystem that already has a filesystem_limit does not
 591        override the ancestor's filesystem_limit, but rather imposes an
 592        additional limit. This feature must be enabled to be used (see
 593        zpool-features(5)).
 594 
 595      fsid_guid=value
 596        Sets the dataset fsid_guid. The fsid_guid is a 64-bit unsigned integer,
 597        used to construct the vfs id when mounting a dataset.  This property
 598        should only be set if you need the vfs id to be identical on two
 599        systems, for example in a NFS migration scenario.  When the fsid_guid
 600        is changed for a file system, the file system and any children that
 601        inherit the mountpoint are unmounted, then remounted. If the file
 602        system was shared, existing NFS clients will require a remount.
 603 
 604      mountpoint=path|none|legacy
 605        Controls the mount point used for this file system. See the Mount
 606        Points section for more information on how this property is used.
 607 
 608        When the mountpoint property is changed for a file system, the file
 609        system and any children that inherit the mount point are unmounted. If
 610        the new value is legacy, then they remain unmounted. Otherwise, they
 611        are automatically remounted in the new location if the property was
 612        previously legacy or none, or if they were mounted before the property
 613        was changed. In addition, any shared file systems are unshared and
 614        shared in the new location.
 615 
 616      nbmand=on|off
 617        Controls whether the file system should be mounted with nbmand (Non
 618        Blocking mandatory locks).  This is used for SMB clients. Changes to
 619        this property only take effect when the file system is umounted and
 620        remounted. See mount(1M) for more information on nbmand mounts.
 621 
 622      primarycache=all|none|metadata
 623        Controls what is cached in the primary cache (ARC).  If this property
