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 git-svn-id: svn://svn.openwrt.org/openwrt/packages@19595 3c298f89-4303-0410-b956-a3cf2f4a3e73

|

The Linux Kernel Device Mapper is the LVM (Linux Logical Volume Management)
|
||||
Team\'s implementation of a minimalistic kernel-space driver that handles
|
||||
volume management, while keeping knowledge of the underlying device layout
|
||||
in user-space. This makes it useful for not only LVM, but EVMS, software
|
||||
raid, and other drivers that create "virtual" block devices.
|
||||
.
|
||||
This package contains the (user-space) shared library for accessing the
|
||||
device-mapper; it allows usage of the device-mapper through a clean,
|
||||
consistent interface (as opposed to through kernel ioctls).

define Package/lvm2/description
|
||||
This is LVM2, the rewrite of The Linux Logical Volume Manager. LVM
|
||||
supports enterprise level volume management of disk and disk subsystems
|
||||
by grouping arbitrary disks into volume groups. The total capacity of
|
||||
volume groups can be allocated to logical volumes, which are accessed as
|
||||
regular block devices.

# I got problems building with readline, so I originally just disabled it.

# CONFIGURE_ARGS += --disable-readline

# Apparently we have problems when "read"ing using O_DIRECT, maybe because
|
||||
# of uClibc. More specifically, with O_DIRECT lvm becomes erratic, showing
|
||||
# non-deterministic behavior: `lvs', `pvs' and friends can return anything
|
||||
# from empty lists, to completely correct result, as well as checksum errors,
|
||||
# complaints about missing volume groups, ... each run of the command can
|
||||
# return something different. The "root" of the problem is (maybe among
|
||||
# other places) in the "_io" function in dev-io.c, where calls to the "read"
|
||||
# function often return garbage, although not always. There's nothing
|
||||
# obviously wrong with the dev-io.c code, so the bug may just as well be in
|
||||
# uClibc or in the kernel (it appeared on the MIPS platform and could be
|
||||
# related to cache coherency issues).
|
||||
# Debian Lenny's lvm2 also disables O_DIRECT on "arm armeb hppa mips mipsel".
