[lvm-devel] [PATCH 0/3] LVM2 topology support



LVM2 topology support to properly align the PV's pe_start using the
associated 'alignment_offset' exposed in sysfs.

Provides manual configuration with pvcreate --dataalignmentoffset and
auto config control via 'devices/data_alignment_offset_detection' in
lvm.conf

Documentation was added to the lvm.conf and pvcreate man pages.

Testing with pvcreate + vgextend + vgreduce + vgextend + vgreduce ...
proved to maintain the pe_start from the initial pvcreate.

Mike Snitzer (3):
  cmdline: support for bytes and sectors
  pvcreate: --dataalignmentoffset
  Add devices/data_alignment_offset_detection to lvm.conf.
