cde70f94db Substantial rework of the functional test support code. Some new features:
- somewhat neater, more consistent and more readable output
- possible to set any lvm.conf value: aux lvmconf "section/key = value"
- LVM_TEST_NODEBUG to suppress the (lengthy) "## DEBUG" output
- back-substitution on test output ($TESTDIR/$PREFIX -> @TESTDIR@/@PREFIX@)
- support code moved from test/ to test/lib/ --> less clutter

2b3a4adff8 Change default alignment of pe_start to 1MB.
The new standard in the storage industry is to default alignment of data
areas to 1MB.  fdisk, parted, and mdadm have all been updated to this
default.

Update LVM to align the PV's data area start (pe_start) to 1MB.  This
provides a more useful default than the previous default of 64K (which
generally ended up being a 192K pe_start once the first metadata area
was created).

Before this patch:
# pvs -o name,vg_mda_size,pe_start
  PV         VMdaSize  1st PE
  /dev/sdd     188.00k 192.00k

After this patch:
# pvs -o name,vg_mda_size,pe_start
  PV         VMdaSize  1st PE
  /dev/sdd    1020.00k   1.00m

The heuristic for setting the default alignment for LVM data areas is:
- If the default value (1MB) is a multiple of the detected alignment
  then just use the default.
- Otherwise, use the detected value.

In practice this means we'll almost always use 1MB -- that is unless:
- the alignment was explicitly specified with --dataalignment
- or MD's full stripe width, or the {minimum,optimal}_io_size exceeds
  1MB
- or the specified/detected value is not a power-of-2

e357c9fc0c Explicitly use non-clustered vgcreate in test.
(So the tests can run under cluster locking and do not require
cluster mirror or snapshots.)

Add vgscan before block device readahead change
(flush long running process - clvmd - dev cache.)

9b2147f608 Fix vgsplit to only move hidden 'snapshotN' LVs when necessary.
This bug has been around for a long time as far as I can tell.
Without this fix, a vgsplit would unconditionally move the
'hidden/internal' snapshot LVs, and result in corrupted metadata
in the following case:
vg1: contains lv1, lv1snap, both on pvset1
vg1: contains lv2, on pvset2

"vgsplit vg1 vg2 pvset2"
would result in "snapshot0" hidden LV being moved to vg2, and
the origin and cow being left in vg1.  The tools detect the
corruption in vg2, but not in vg1.

6381666df4 Update vgsplit tests.
- Add validation on pv_count, lv_count, and snap_count after split
NOTE: Some of these counts are misleading.  If you compare "lvs" output
with these counts you will be left scratching your head what a "logical volume"
really is.  ;-)
