Use only selected paths for finding .so in builddir.
So if builddir constains some embeded subdirs with some more
occurences of project (i.e. 'make rpm' build subdir)
those library paths will not get into list.
In order to support striped raid5/6/10 LV reshaping (change
of LV type, stripesize or number of legs), this patch
introduces the changes to call the reshaping infratructure
from lv_raid_convert().
Changes:
- add reshaping calls from lv_raid_convert()
- add command definitons for reshaping to tools/command-lines.in
- fix raid_rimage_extents()
- add 2 new test scripts lvconvert-raid-reshape-linear_to_striped.sh
and lvconvert-raid-reshape-striped_to_linear.sh to test
the linear <-> striped multi-step conversions
- add lvconvert-raid-reshape.sh reshaping tests
- enhance lvconvert-raid-takeover.sh with new raid10 tests

When the test would need to try to write some large amount of data
we can give it 'zero' segments - for obvious reason such written data
can't be verified but in some test cases it doesn't really matter.
Usage follows 'error_dev' style.
For now test suite is not supporting any combination of
error/delay/zero segments so only 1 type could be used per PV.
Check 'dmsetup version' is called before starting any more
advanced logic in $DM_DEV_DIR.
Call also replaces mkdir as it creates needed path with control node.
- support shrinking of raid0/1/4/5/6/10 LVs
- enhance lvresize-raid.sh tests: add raid0* and raid10
- fix have_raid4 in aux.sh to allow lv_resize-raid.sh
and other scripts to test raid4

Since we still experience occasiaonal test failure - slow
things down even more to avoid race.
Add support for 'quick' table changes between normal & delayed tables.
0 interval leads as of now to a busy loop with lvmetad and command.
Avoid testing this patological case.
TODO: Code should possibly translate zero interval into some small
sleep. With lvmpolld it's already 1/10s
Add simple helper/wrapper check function to check result
of dmsetup call i.e.:
check grep_dmsetup table vg-lv "grep_expected"
check grep_dmsetup status vg-lv -v "grep_unexpected"
'lvchange --resync LV' or 'lvchange --syncaction repair LV' request the
RAID layout specific parity blocks in raid4/5/6 to be recreated or the
mirrored blocks to be copied again from the master leg/copy for raid1/10,
thus not allowing a rebuild of a particular PV.
Introduce repeatable option '--[raid]rebuild PV' to allow to request
rebuilds of specific PVs in a RaidLV which are known to contain corrupt
data (e.g. rebuild a raid1 master leg).
Add test lvchange-rebuild-raid.sh to test/shell doing rebuild
variations on raid1/10 and 5; add aux function check_status_chars
to support the new test.

When logging to epoch files we would like to prevent creating too large
log files otherwise a spining command could fulfill available space
very easily and quickly.
Limit for to 100000 per command.
TODO: it might be better to log dmeventd messages with test output
just like we do with clvmd - maybe we will switch to this one
instead of extra DMEVENTD log file in future....
Add config for mkfs to get more predicatable results
when using mkfs across variety of distributions.
In future maybe use this per all tests as default.
For now user has to specify in a test MKE2FS_CONFIG envvar to use it.
When force removing thin-pool we loose 'real' access to hidden device,
and if such pool is in suspended state, any thin volume cannot be
dropped. It likely should be also checked by dmsetup, but meanwhile
apply simple logic - try to force remove first all higher minors first
with assumption we first create thin-pool and then thin volume
and there are usually not being released lower dm numbers to
get the order wrong.
For raid1 use chunksize as bitmap-chunk specification.
Always enforce usage of bitmap - getting comparable outcome
as lvm2 raid support uses.
Add udev_wait after stopping md array - as in fact leg-device
are still in use by target even command has finished.
(mdadm --stop causes WATCH rule wakeup, and
ioctl(STOP_ARRAY) returns IMHO to early - it should finish
and fsync work on leg devices first).
Using lvm1 metadata with lvmetad is not generally allowed,
but nothing has prevented creating new lvm1 metadata with
lvmetad (missing error checking in pvcreate/vgcreate.)
Various tests are using lvm1 with lvmetad and happen to
work because of the missing error checks.
This commit fixes the tests so they won't fail when the
lvm1/lvmetad error checking is fixed. A new variable
LVM_TEST_LVM1 is defined and is used in the scripts to
decide if lvm1 metadata should be tested. LVM_TEST_LVM1
is not defined when lvmetad is being tested, and the
combination of LVM_TEST_LVM1 and LVM_TEST_LVMETAD can
be used to verify the desired lvmetad+lvm1 behavior.
Rather then skipping whole test - just do not use it.
Failing tests that have required delay need to deal with reality
and shell either check for HAVE_DM_DELAY and skip portion
of test or using should when needed.
Avoid running tests, when prefix already exist in the system.
As prefix just uses PID number, we may hit a case for long
running tests, where devices from some previous runs were not
properly cleared away - detect this and fail early.
(Such machine should be inspected and fixed).
Hopefull 4.3 will be fixed and test will be updated to let
raid test running again.
Meanwhile using md-raid may effectively kill kernel,
so leave at least other tests running.
Since now we enable those by default when compiled with those daemons,
explicitely disable them in tests when needed.
Alphabetically sort configurables.
Introduce LVM_TEST_LVMETAD_DEBUG_OPTS to allow to override
default debug opts for lvmetad.
However could be still overloaded on command line:
make check_lvmetad LVM_TEST_LVMETAD_DEBUG_OPTS="-l all"...
Better name for aux function.
First use normal -TERM, and only after a while use -KILL
(leaving some time to correctly finish)
Print INFO about killed processes.
New lvmconf function is using bash associative arrays - however
older systems like RHEL5 doesn't provide this feature. In this case
stay with older variant.
Restore support for use case like this:
aux lvmconf 'tags/@foo {}'
some tests left dangling bg processes originating in
lvm2 commands being able to spawn any bg polling process
(lvchange, vgchange, pvmove, lvconvert...)
Initial fn 'add_to_kill_list' should collect processes with
specific parameters (proc's command line and parent processes ID).
After testing finishes the fn kill_listed_processes should remove these
listed by 'add_to_kill_list'.
Unfortunately it proved to be prone to an error especially in scenarios
where cmd line of initiating command contained characters required to
be espaced before passing to shell script to make it work correctly.
(Or if cmd spawned more than one bg process with same cmd line. i.e.:
vgchange or lvchange).
The new implementation is much simpler. It uses env. variable (LVM_TEST_TAG)
for marking a process desired to be killed later or during test env. teardown.
(i.e.: LVM_TEST_TAG=kill_me_$PREFIX to kill only processes related to
current test environment)
When test is executed on real device - lets try a more complete
cleanup - discard whole device first and try to wipe any
headers it might be left from previous test.
When test suite is used from installed rpm package
we need to handle things better.
This patch is rather first approach - expecting few more
tweaks needed.
Enhance 'not' to manage autodeletion of log files in right cases.
Use separately marked epoch log files for clvmd and dmeventd.
Properly manage stack tracing for new debug.log names.
Previous commit has made have_cache & have_thin producing
false return value.
Fix it and at the some time provide much better reconfiguring
warning message.
If the test machine is missing needed and configured binaries
it will produce TEST WARNING result.
Put in pvmove background process into list quickly.
Update API for aux add_to_kill_list()/kill_listed_processes().
Run on 'background' (&) only non-background pvmoves.
If the system is correctly configure (cache & thin tools are present)
avoid 'extra' rebuild of configuration.
On the other hand - if some tool is missing - duplicate ##LVMCONF should
make it more straighforward to see.
Reenable TESTDIR & PREFIX replacement.
Since we need to replace string in proper order (1st. @TESTDIR@,
2nd. @PREFIX@), drop map and use plain string.
Drop timestamp logging when 'stacktracing'
When clvmd starts, it starts it's own command logging into debug.log.
This is interferring with our other command debug.log.
As as sideeffect we may experience log from command,
followed but lots of zeros and continued with clvmd log.
Fix it by renaming debug.log and now we could also print this trace
to get full list of clvmd activity nicely.
Also improve some post-mortem prints from udevadm and dmsetup to
make the output more usable.
Use common code for error_dev & delay_dev.
Both functions now take list of sectors.
From now on we could delay just 'extent' section, while
keeping running lvm commands fast (having native metadata area).
When we use /dev/loopX device - shift first PV1 sector by 1M
so /dev/loop0 and dm device do not appear as same device.
Also notify lvmetad once 'devs' are created - so in case this
command is called in the middle of test - lvmetad properly
drops its metadata for these devices.
Drop used test.img file between reuse so the 'prepare_vg'
always starts with zeroed disks.
When LVM_TEST_AUX_TRACE is set, allow shell tracing of aux commands.
Avoid busy-looping on CPU while reading socket pipe
and always call read only when select tells there is
something for read.
Change the batch output to old nicer output.
Make sure there is 'control' node before clvmd is started.
Somehow 'clvmd' is not allowed by selinux to create one.
TODO: Check is selinux policy is right here...
Add more time for tests, since debug kernels are getting slower...
and we add more and more tests.
However many test should be shortened to avoid testing disk-perfomance
and focus on lvm functionality...
(Often we should probably test with inactive volumes when we check
metadata operation of lvm2)
We may need to support option for 'DEEP' longer testing.
Also something like LVM_TEST_TIMEOUT_FACTOR might be useful
though it would be much better if test suite could approximete
from system perfomance test lenght...
Instead of rereading device list via cat - keep
the list in bash array. (Also solves problem
with spaces in device path)
Move usage of "$path" out of lvm shell usage,
since we don't support such thing there...
disable_dev can't use transaction - since it may lead occasionaly to
weird error - example could be nomda-missing.sh test case.
Here occasionaly device instead of being removed was left as
error device and testing different code path (which is unfortunatelly
buggy)
When we want to test 'error' device - 'aux error_dev()' should be used.
