From 757a42719635495779462514458bbfbf12a37dac Mon Sep 17 00:00:00 2001 From: David Teigland Date: Thu, 20 Oct 2011 13:26:28 -0500 Subject: dlm: add node slots and generation Slot numbers are assigned to nodes when they join the lockspace. The slot number chosen is the minimum unused value starting at 1. Once a node is assigned a slot, that slot number will not change while the node remains a lockspace member. If the node leaves and rejoins it can be assigned a new slot number. A new generation number is also added to a lockspace. It is set and incremented during each recovery along with the slot collection/assignment. The slot numbers will be passed to gfs2 which will use them as journal id's.
