Hi, I am curious what people think on this subject. In the case that you have a database running on hardware which has two separate data volumes (lets call them data1 and data2), what is the "best" way for PostgreSQL to use those two volumes? So sitting here I can think of two very simple ways of allowing PostgreSQL to use those two volumes: 1) Tablespaces with simple partitions - This is simply create them as /data1 and /data2 then run "create tablespace" to create an additional tablespace on the second data partition then move objects into it. 2) LVM - Use LVM to create one single partition (which encompasses both volumes, for the purposes of this I am assuming these volumes are already redundant behind hardware raid), then we have the default tablespace which sits on the larger LVM volume. So what do people think is the "best" way and why? By "best", I dont have any preconditions in mind, some people may consider blistering performance to be the number one concern and others may consider ease of maintenance to be the number one, either way both are valid interpretations of "best" and there might be different answers, hence I am wondering what people think is best and what makes it best? Thanks for your time.
