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. Signed-off-by: David Teigland <teigland@redhat.com>
