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.
v2 changes:
Also added another method for auto detection of --dataalignment using
the topology information that is exposed in sysfs. Controlled via
'devices/data_alignment_detection' in lvm2.conf.
v3 changes:
Fixed 'devices/data_alignment_detection' patch (3/6) to retrieve the
minimum_io_size and optimal_io_size for partitions from the parent
device's 'queue/'. Both attributes are found in 'queue/'
v4 changes:
Simplified the _mda_setup() change in --dataalignmentoffset patch (1/6).
Improved the documentation and comments in all patches.
v5 changes:
Improved LVM2's support for partitions (in the MD and topology code paths).
Added MD, partitions, and topology tests to the testsuite.
v6 changes:
Added pe_align_offset to 'struct physical_volume'; Added
set_pe_align_offset(). After pe_start is initialized pe_align_offset is
added to it.
Mike Snitzer (6):
Add --dataalignmentoffset to pvcreate to pad aligned data area
Add devices/data_alignment_offset_detection to lvm.conf.
Add devices/data_alignment_detection to lvm.conf.
Improve ability to lookup primary device associated with partition
Retrieve MD sysfs attributes for MD partitions
Add MD, partition and topology tests to the LVM2 test-suite
