From db07d85ef6395d4768c6cdceeb2ea4878bd2a3f4 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 11 Oct 2012 14:22:17 +1100 Subject: md: make sure manual changes to recovery checkpoint are saved. If you make an array bigger but suppress resync of the new region with mdadm --grow /dev/mdX --size=max --assume-clean then stop the array before anything is written to it, the effect of the "--assume-clean" is lost and the array will resync the new space when restarted. So ensure that we update the metadata in the case.
