From 9a51ab1c1b3c1e21f076cdd571bbe6ca7d1b504c Mon Sep 17 00:00:00 2001 From: Philipp Reisner Date: Mon, 20 Feb 2012 21:53:28 +0100 Subject: drbd: New disk option al-updates By disabling al-updates one might increase performace. The price for that is that in case a crashed primary (that had al-updates disabled) is reintegraded, it will receive a full-resync instead of a bitmap based resync.
