This patch is not fully tested and leaves some related bugs unfixed.
Intended behaviour of the code now:
pe_start in the lvm2 format PV label header is set only by pvcreate (or
vgconvert -M2) and then preserved in *all* operations thereafter.
In some specialist cases, after the PV is added to a VG, the pe_start
field in the VG metadata may hold a different value and if so, it
overrides the other one for as long as the PV is in such a VG.
Currently, the field storing the size of the data area in the PV label
header always holds 0. As it only has meaning in the context of a
volume group, it is calculated whenever the PV is added to a VG (and can
be derived from extent_size and pe_count in the VG metadata).
"test" never prints anything. Therefore, "return $(test ...)" is equivalent to
just "return;" which means success in sh (same as return 0). We can however,
thanks to set -e, use "test foo = bar" as an assertion.
PS: test a == b is invalid syntax. It is either = or -eq: = is textual and -eq
is numeric comparison.
for losetup, break out of the loop when successful setup of loop device,
and only look at 7 loop devices (default loop module setting)
for blockdev, use old option if new one is not available
- add lvcreate rejects repeated invocation test
- fix pvs metadata test for partial failure test
- add pvchange reject --addtag to lvm1 pv test

Original code would create "*.so" symbolic links if there were no actual
files ending in "so". The second iteration would then cause an error
in the test logs.
Failure to check for label_write() return code caused the following test
to indicate it passed when it really failed:
pvcreate rejects labelsector > 1000000000000
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.
- 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. ;-)
Fix 'make check' to use DMDIR to check DM_DEV_DIR support in dmsetup.
Add basic test cases for mirrored LV.
Add basic test cases for lvconvert mirror.
Add basic test cases for pvmove.
Jun'ichi Nomura <j-nomura@ce.jp.nec.com>
Add new vgsplit and vgmerge tests.
Dave Wysochanski <dwysocha@redhat.com>
* test/t-000-basic.sh: Invoke initial test of lvm with its "version"
argument, so that the behavior of the tool doesn't depend on whether
readline was enabled at configure time.
Author: Jun'ichi Nomura <j-nomura@ce.jp.nec.com>
Committer: Jim Meyering <meyering@redhat.com>
This makes the tests more reproducible and helps isolate
them from any existing LVM set-up.
* test/Makefile.in (abs_builddir): Define.
(init.sh): Emit definition of abs_builddir.
* test/lvm-utils.sh (unsafe_losetup_): Keep only the portable,
iterative approach.
(dmsetup_has_dm_devdir_support_): New function.
(init_root_dir_): New function.
Invoke init_root_dir_ for all but the first test.
* test/test-lib.sh (this_test_): Adapt to test-name change.
Invoke lvm-utils.sh much later (after tmpdir creation), and
only if the current test is not being skipped.
Remove useless abs_top_srcdir definition.
Rename t0->test_dir_rand_.
* test/t-lvcreate-pvtags.sh: Skip this test if the available
version of dmsetup is not new enough.
Use global, $G_dev_, rather than hard-coded "/dev".
* test/t-lvcreate-usage.sh: Make --verbose output more useful.
Author: Jim Meyering <jim@meyering.net>
Committer: Jim Meyering <meyering@redhat.com>
* test/Makefile.in (srcdir, top_srcdir): Use @srcdir@, etc.
(top_builddir, abs_srcdir, abs_top_builddir, abs_top_srcdir): Likewise.
(so_name): Remove definition.
(.bin-dir-stamp): No longer create symlink in $(DMDIR) tree.
Prompted by suggestions from Alasdair Kergon.
* test/t1000-lvcreate-usage.sh (cleanup_): Redirect to a file,
rather than to /dev/null.
Change wording of some test titles.
Suggestions from Alasdair Kergon.
* test/Makefile.in: Add a copyright notice.
* test/lvm-utils.sh: Likewise.
* test/mkdtemp: Likewise.
* test/t0000-basic.sh: Likewise.

* test/test-lib.sh: Likewise.
Author: Jim Meyering <jim@meyering.net>
* test/t1000-lvcreate-usage.sh: New tests.
* test/Makefile.in (T): Add it.
Derived from test cases by Dave Wysochanski.
Author: Jim Meyering <jim@meyering.net>
* test/Makefile.in (so_name): Use @DMDIR@.
(.bin-dir-stamp): Create symlink only if @DMDIR@ is nonempty.
(lvm-wrapper): Emit LD_LIBRARY_PATH setting only if @DMDIR@ is nonempty.
Based on a patch from Jun'ichi Nomura.
