(such as ppc64 and s390x).
Node-specific files are referred to as local files. A node slot
number is appended to the local file. For example: journal:0000
belongs to whatever node is assigned to slot number 0.
Set each volume's maximum number of node slots when you

utility to increase the number of node slots as needed; the value
cannot be decreased.

Specify the block size when you create the volume.
Options are 512 bytes (not recommended), 1 KB, 2 KB, or 4
