  45 define Package/libdevmapper/description
  46   The Linux Kernel Device Mapper is the LVM (Linux Logical Volume Management)
  47   Team\'s implementation of a minimalistic kernel-space driver that handles
  48   volume management, while keeping knowledge of the underlying device layout
  49   in user-space.  This makes it useful for not only LVM, but EVMS, software
  50   raid, and other drivers that create "virtual" block devices.
  51   .
  52   This package contains the (user-space) shared library for accessing the
  53   device-mapper; it allows usage of the device-mapper through a clean,
  54   consistent interface (as opposed to through kernel ioctls).

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

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