aux updates:
prepare_vg now created clustered VG for cluster tests.
since dm-raid doesn't work in cluster, skip the cluster
test when someone checks for dm-raid target until fixed.
Aux function to replace PV with specifically damaged device.
Usage:
aux error_dev "$dev1" 8:32 96:8
Replaces from 8 sector 32 error 512b sectors
and from 96 sector next 8 sectors will fail on rw.
Rest of device is preserved.
For testing:
dd if="$dev1" of=x bs=512 count=104 conv=sync,noerror iflag=direct
When valgrind usage is desired by user (--enable-valgrind-pool)
skip playing/closing/reopenning with descriptors - it makes
valgridng useless.
Make sleep delay for clvmd start longer.
- logging is not controlled by "levels" but by "types"; types are
independent of each other... implementation of the usual "log level"
user-level semantics can be simply done on top; the immediate
application is enabling/disabling wire traffic logging independently
of other debug data, since the former is rather bulky and can easily
obscure almost everything else
- all logs go to "outlets", of which we currently have 2: syslog and
stderr; which "types" go to which "outlets" is entirely configurable
Add make help target.
Add LVM_TEST_PARALLEL to support parallel runs of tests
Work around the problem the dmsetup table/info may return error
by using dmtable and dminfo function that will use 'should'.
(Error happens when some concurently running process removes table
entry while dmsetup command resolves table entries inside the loop.)
Make the teardown really usable - it will try down to remove all the left
devices even from previous test runs
(the only missing piece is probably proper mdadm teardown)
Add few more local vars
Try to setup PATH and LD_LIBRARY_PATH just once.
Try shorter sleeps.
Indent
Add valgrind support:
env LVM_TEST_VALGRIND={0123} (the higher level, more commands tested)
env LVM_TEST_CLVMD=1 runs clvmd within valgrind.
env VALGRIND script name executed for each lvm command (def. is valg).
Smarted teardown - should minimize occurence of left dev entries
(using dmsetup remove -f only as last resort)
sort removed devices by open count before actual removal
Use "" around string that may contain spaces.
Set log/verbose and activation/retry_deactivation to defined value.
Remove debug.log after successful lvm command (easier to check output).
Currently we could not test special prefixes in our test suite.
As teardown will not find such device and basicaly busyloops here,
as at cannot remove such names.
This patch adds possibity to use:
vgcreate V_$vg1 $dev
Note: you still need to use $PREFIX somewhere in the name.
(And of course, it's really bad idea to use $PREFIX (=LVMTEST)
for normally used LVs)
The only purpose of this patch is to allow testing cluster with
special vg names that begins with V_ , P_....
When running tests it might be useful to have an override option when
testing on real /dev and some broken system (i.e. Debian and its rules).
So one can use:
LVM_TEST_DEVDIR=/dev LVM_VERIFY_UDEV=1 make check
Test whether nodes could be used on given filesystem where TMP
dir is being used and skip teardown quicker in fail case.
(makes the problem quickly obvious if you try to such fs).
Skip teardown_dev if we have not created any devs yet.
and do not mkdir /dev/mapper dir when LVM_TEST_DEVDIR is set.
Drop this test from t-000-basic.sh.
daemon/common code in a single libdaemon.a, which is completely private. This
is currently linked into the lvmetad binary, and will be linked into LVM (the
client part, since static linking only picks up only symbols that are actually
used). I have also added --enable/disable-lvmetad to ./configure; although the
current default is off, I expect this to be flipped to on shortly. There's no
LVM-side support yet, but when there is, even when built, it'll still need to
be enabled by an lvm.conf option.
Add config option to enable crc checking of VG structures.
Currently it's disabled by default.
For the internal test-suite this check it is enabled.
Note: In the case the internal error is detected, debug build with
compile option DEBUG_ENFORCE_POOL_LOCKING helps to catch the source
of the problem.
