aebf2d5cdc Add experimental code for activation of thinp targets

10d0d9c7c4 Introduce revert_lv for better pvmove cleanup.
(One further fix needed to remove the stray pvmove LVs left behind.)
2011-09-27 22:43:40 +00:00
Alasdair Kergon
74e72bd75d Replace incomplete pvmove activation failure recovery code with a message.
As it stands, the recovery code can make things worse sometimes so it's
better to insist on a proper 'pvmove --abort' cleanup.

1c26860d82 Abort if _finish_pvmove suspend_lvs fails instead of cleaning up incompletely.
Change suspend_lvs to call vg_revert internally.
Change vg_revert to void and remove superfluous calls after failed vg_commit.

7ae124743e Use execvp for clvmd restart
Since execve passed only NULL as environ, we had lost all environment vars on
restart - thus actually running  'different' clvmd then the one at start.

Preserving environ allows to restart clvmd with the same settings
(i.e. LD_LIBRARY_PATH)

Add test for second restart.

807a5a7b13 Remove test for NULL
Since it's internal function and we always check for NULL value
before call - this is safe.

Just for case add nonnull attribute so analyzer might better
catch error.

5ce39c67e5 Replace test for NULL of root->child with test for NULL l
It's 100% equivalent test - since it always happen for the first iteration.
But the check for 'l' is understandable with analyzers - since analyzer
is not smart enough to deduce connection between  root->child == NULL.

90d106ef19 Restart CLVMD with same cluster manager
Add named cluster_ops to easily learn the name of the active cluster manager,
so we are able to restart singlenode manager in testing.

Add simple test for clvmd -S  (restart) and -R (refresh)
(though it needs some extensions).

f1ab501a58 Fix log_error() usage
Cosmetic - skip <bactrace> when error has been just printed in raid segtype.
Add missing log_error if allocation would fail for unknown segtype.

102dd99ca4 Allow overwrite for VERIFY_UDEV
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

13dd31381c Use Makefile for daemmons/common library.
Next iteration for better fit of lvmetad compilation.

Move build of libdaemon.a into common subdir Makefile.
libdaemon.a is device-mapper target.

518164ce96 Detect unusable nodes on fs
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.

d2c116058e CLVMD support for LVM_CLVMD_BINARY and LVM_BINARY
Read 2 environmental vars to learn about overide position for
CLVMD and LVM binaries.

We support LVM_BINARY in other script - and this way we could easily
test restart in our test-suite.

a039e204e7 CLVMD bugfix support for args -S -E
Bugfix:
Add (most probably unfinished) support for -E arg with list of exclusive
locks.  (During clvmd restart all exclusive locks would have been lost and
in fact, if there would have been an exclusive lock, usage text would be
printed and clvmd exits.)

Instead of parsing list options multiple times every time some lock UUID is
checked - put them straight into the hash table - make the code easier to
understand as well.

Remove  was_ex_lock() function (replaced with dm_hash_lookup()).

Swap return value for get_initial_state() (1 means success).

Update man pages and usage info for -E option.
