From 0fe8ed5ccb19cf5fc4a55af1b44a6664c971b5af Mon Sep 17 00:00:00 2001 From: "Bryn M. Reeves" Date: Wed, 26 Apr 2017 14:15:15 +0100 Subject: [PATCH] lvm_scan.sh: use -K when calling lvchange The --ignoreactivationskip/-K switch was added to LVM2 in 2.02.99 (July 2013) and is used to control the activation of volumes with the activation skip flag set: without -K these volumes will be ignored when 'lvchange -ay $LV' is issued. This prevents an LVM2 thin-privisioned snapshot from being used as the root device when booting with rd.lvm.lv=vg/lv since the activation skip flag is set for these snapshots by default (the legacy non-thinp snapshots do not set this flag and can already be activated and used as a root device by specifying appropriate values for rd.lvm.lv). This is only used in the rd.lvm.lv case since in that situation we are activating one or more named LVs specified by the user: the flag is not given when calling 'vgchange' since this may cause many unwanted volumes to be activated during early user space. Users wishing to use a specific snapshot volume should specify it with 'rd.lvm.lv'.
