1064 .It Sy fsid_guid Ns = Ns Sy value Ns
1065 Sets the dataset fsid_guid. The fsid_guid is a 64-bit unsigned integer, used to
1066 construct the vfs id when mounting a dataset.
1067 This property should only be set if you need the vfs id to be identical on two
1068 systems, for example in a NFS migration scenario.
1069 When the fsid_guid is changed for a file system, the file system and any
1070 children that inherit the mountpoint are unmounted, then remounted. If the
1071 file system was shared, existing NFS clients will require a remount.
