Failure on pipe kills lv command and produces memory stacktrace.
Add 'true' for empty grep/sed to avoid generating stacktrace.
This should help with long time (7min) for this test on Lenny testing maching
(mimage was filler with stacktrace and each word was used as LV name).
This lvconvert is now able to complete operation automatically without question.
So remove 'echo y |' - it's breaking pipe on some bash versions.
i.e.:
+ echo y
./t-lvconvert-mirror-basic.sh: line 104: echo: write error: Broken pipe
while command has completed this operation succesfully
Currently the test are not properly working with new code.
Use settings for the previous behaviour.
FIXME: update tests to properly test new allocation policies.
Add a small fix that preserves pe_start for lvm1 PVs when being converted.
(this fix needs to be replaced with something more clever, but let's have this working now)
Add configurable option to define minimal size of
of block device usable as a PV.
pv_min_size() is added to lvm-globals and it's being
initialized through _process_config.
Macro PV_MIN_SIZE is unused and removed.
New define DEFAULT_PV_MIN_SIZE_KB is added to lvm-global
and unlike PV_MIN_SIZE it uses KB units.
Should help users with various slow devices attached to the system,
which cannot be easily filtered out (like FDD on /dev/sdX):

Instead of implicitly syncing udev operation in clustered and
file locking code - call synchronization directly in lock_vol() when
the operation unlocks VG
The problem is missing implicit fs_unlock() in the no_locking code.
This is used with --sysinit on read-only filesystem locking dir.
In this case vgchange -ay could exit before all udev nodes are properly
synchronised and may cause problems with accessing such node right after
vgchange --sysinint command is finished.
Add test case for vgchange --sysinit.
As the option 'set -e -o pipefail' is very sensite on pipe breaking
stop using '-q' for grep commands.
Otherwise this command (with large enough table) would fail:
dmsetup table | egrep -q
with exit code 141 (128 + SIGPIPE)
As Peter suggested, he prefers to keep '-o pipefail' - so make sure all
piped commands will read the whole output and will not exit too early.
Instead of checking $LOCAL_CLVMD set during some 'aux' execution which
doesn't seem to be propagated to this shell - check for existance of pid
file of clvmd process - so this test is skipped in singlenode cluster test.
Harness seems to be able to busyloop in while cycle and not moving forward
for certain buffer - so check whethere there was some progress.
This fix allows to continue after failed cluster test.
Fix gcc warning for hiding global variable 's' -> sig.
- somewhat neater, more consistent and more readable output
- possible to set any lvm.conf value: aux lvmconf "section/key = value"
- LVM_TEST_NODEBUG to suppress the (lengthy) "## DEBUG" output
- back-substitution on test output ($TESTDIR/$PREFIX -> @TESTDIR@/@PREFIX@)
- support code moved from test/ to test/lib/ --> less clutter
to lvm.conf in the activation section: 'snapshot_autoextend_threshold' and
'snapshot_autoextend_percent', that define how to handle automatic snapshot
extension. The former defines when the snapshot should be extended: when its
space usage exceeds this many percent. The latter defines how much extra space
should be allocated for the snapshot, in percent of its current size.
Current lvm1 allocation code seems to not properly
map segments on missing PVs.
For now disable this functionality.
(It never worked and previous commit just introduced segfault here.)
So the partial mode in lvm1 can only process missing PVs
with no LV segments only.
Also do not use random PV UUID for missing part but use fixed
string derived from VG UUID (to not confuse clvmd tests).
If some lvm1 device is missing, lvm fails on all operations
# vgcfgbackup -f bck -P vg_test
Partial mode. Incomplete volume groups will be activated read-only.
3 PV(s) found for VG vg_test: expected 4
PV segment VG free_count mismatch: 152599 != 228909
PV segment VG extent_count mismatch: 152600 != 228910
Internal error: PV segments corrupted in vg_test.
Volume group "vg_test" not found
Allow loading of lvm1 partial VG by allocating "new" missing PV,
which covers lost space. Also this fake mising PV inform code
that it is partial VG.

For now force it in lvm.conf (otherwise it fails on older systems like RHEL5
where are these options disabled by default).
FIXME: it should test and detect both versions.
detected alignment.
NOTE: lvm2 doesn't detect MD 1.2 metadata (now the default on RHEL6) so
for now I'm forcing 1.0 metadata. This was needed to be able to reuse
the existing loop devices but recreate the md device with different
raid0 striping.
