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

  63   This is LVM2, the rewrite of The Linux Logical Volume Manager.  LVM
  64   supports enterprise level volume management of disk and disk subsystems
  65   by grouping arbitrary disks into volume groups. The total capacity of
  66   volume groups can be allocated to logical volumes, which are accessed as
  67   regular block devices.

  73
  74 # Apparently we have problems when "read"ing using O_DIRECT, maybe because
  75 # of uClibc.  More specifically, with O_DIRECT lvm becomes erratic, showing
  76 # non-deterministic behavior: `lvs', `pvs' and friends can return anything
  77 # from empty lists, to completely correct result, as well as checksum errors,
  78 # complaints about missing volume groups, ... each run of the command can
  79 # return something different.  The "root" of the problem is (maybe among
  80 # other places) in the "_io" function in dev-io.c, where calls to the "read"
  81 # function often return garbage, although not always.  There's nothing
  82 # obviously wrong with the dev-io.c code, so the bug may just as well be in
  83 # uClibc or in the kernel (it appeared on the MIPS platform and could be
  84 # related to cache coherency issues).
  85 # Debian Lenny's lvm2 also disables O_DIRECT on "arm armeb hppa mips mipsel".
