From 9dbe9610b9df4efe0946299804ed46bb8f91dec2 Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Wed, 31 Oct 2012 10:37:10 +0000 Subject: GFS2: Add Orlov allocator Just like ext3, this works on the root directory and any directory with the +T flag set. Also, just like ext3, any subdirectory created in one of the just mentioned cases will be allocated to a random resource group (GFS2 equivalent of a block group). If you are creating a set of directories, each of which will contain a job running on a different node, then by setting +T on the parent directory before creating the subdirectories, each will land up in a different resource group, and thus resource group contention between nodes will be kept to a minimum.
