Whole purpose of NUFA is to give affinity to local disks. In a replicated mode, writes
have to be written across servers. We implemented NUFA solely for HPC scratch processing.
For most work loads, plain distribute is recommended.
See this example below: You need local-volume-name option. Make sure you also include
write-behind, read-ahead and io-cache translators for performance.
volume nufa
type cluster/nufa
option local-volume-name `hostname` # note the backquote, so 'hostname' output will be
used as the option.
subvolumes node01 node02 node03 node04
end-volume
