From 9e5844fda2400b5668188baf0ae3b7a68bb176b5 Mon Sep 17 00:00:00 2001 From: Travis Kemen Date: Fri, 12 Feb 2010 01:37:02 +0000 Subject: [PATCH] Here is LVM support for OpenWRT. It introduces 3 new packages: - kmod-dm for the device mapper kernel module. - kmod-libdevmapper for the device-mapper library. - kmod-lvm2 for the lvm tool. Note that it currently does not create the symlinks for all the lvm tools, so you have to use lvm pvs rather than just pvs. Thanks Stefan Monnier SVN-Revision: 19595 --- .../files/etc/hotplug2-common.rules | 6 ++++ package/kernel/modules/block.mk | 29 +++++++++++++++++++ 2 files changed, 35 insertions(+) diff --git a/package/base-files/files/etc/hotplug2-common.rules b/package/base-files/files/etc/hotplug2-common.rules index d6dd6e8a9b..a7aba35a93 100644 --- a/package/base-files/files/etc/hotplug2-common.rules +++ b/package/base-files/files/etc/hotplug2-common.rules @@ -34,6 +34,12 @@ DEVPATH is set, SUBSYSTEM ~~ (input) { makedev /dev/input/%DEVICENAME% 0644 } +DEVICENAME == device-mapper { + nothrottle + makedev /dev/mapper/control 0600 +} + + DEVPATH is set { nothrottle makedev /dev/%DEVICENAME% 0644 diff --git a/package/kernel/modules/block.mk b/package/kernel/modules/block.mk index b1804337cd..34c6f99276 100644 --- a/package/kernel/modules/block.mk +++ b/package/kernel/modules/block.mk @@ -360,6 +360,35 @@ endef $(eval $(call KernelPackage,nbd)) +define KernelPackage/dm + SUBMENU:=$(BLOCK_MENU) + TITLE:=Device Mapper + # All the "=n" are unnecessary, they're only there + # to stop the config from asking the question. + # MIRROR is M because I've needed it for pvmove. + KCONFIG:= \ + CONFIG_BLK_DEV_MD=n \ + CONFIG_DM_DEBUG=n \ + CONFIG_DM_CRYPT=n \ + CONFIG_DM_UEVENT=n \ + CONFIG_DM_DELAY=n \ + CONFIG_DM_MULTIPATH=n \ + CONFIG_DM_ZERO=n \ + CONFIG_DM_SNAPSHOT=n \ + CONFIG_MD=y \ + CONFIG_BLK_DEV_DM \ + CONFIG_DM_MIRROR + FILES:=$(LINUX_DIR)/drivers/md/dm-*.$(LINUX_KMOD_SUFFIX) + AUTOLOAD:=$(call AutoLoad,30,dm-mod dm-region-hash dm-mirror dm-log) +endef + +define KernelPackage/dm/description + Kernel module necessary for LVM2 support +endef + +$(eval $(call KernelPackage,dm)) + + define KernelPackage/pata-rb153-cf $(call KernelPackage/ata/Depends,@TARGET_adm5120_router_le) TITLE:=RouterBOARD 153 CF Slot support
