[gpfsug-discuss] RAID config for SSD's - potential pitfalls

[Marc A Kaplan]

Kevin asked: " ...  data pools they all must have the same replication, 
correct?"

Actually no! You can use policy RULE ... SET POOL 'x' REPLICATE(2) to set 
the replication factor when a file is created. Use  mmchattr or 
mmapplypolicy to change the replication factor after creation.  You 
specify the maximum data replication factor when you create the file 
system (1,2,3), but any given file can have replication factor set to 1 or 
2 or 3.
