We need to use "--verifyudev" for dmsetup mangle command used in
the name-mangling test since without the --verifyudev, we'd end up
with the failed rename.
Also, add direct check for the dev nodes - node with old name must
be gone and node with new name must be present. Before, we checked
just the output of the command.
One bug popped up here when renaming with udev and libdevmapper
fallback checking the udev when target mangle mode is "none"
(fixme added in the libdevmapper's node rename code).
Use separate files for raid1, raid456, raid10.
They need different target versions to work, so support
more precise test selection.
Optimize duplicate tests of target avalability and skip
unsupported test cases sooner.
In cases where PV appears on a new device without disappearing from an old one
first, the device->pvid pointers could become ambiguous. This could cause the
ambiguous PV to be lost from the cache when a different PV comes up on one of
the ambiguous devices.
This is probably not optimal, but makes the lvmetad case mimic non-lvmetad code
more closely. It also fixes vgremove of a partially corrupt VG with lvmetad, as
_vg_write_raw (and consequently, entire vg_write) currently panics when it
encounters a corrupt MDA. Ideally, we'd be able to explicitly control when it is
safe to ignore them.
%FREE allocation has been broken for RAID. At 100%FREE, there is
still an extent left for certain tests. For now, change the test
to warn rather than completely fail.
Condition was swapped - however since it's been based on 'random'
memory content it's been missed as attribute has not been set.
So now we have quite a few possible results when testing.
We have old status without separate metadata and
we have kernels with fixed snapshot leak bug.
(in-release update)
Code uses target driver version for better estimation of
max size of COW device for snapshot.
The bug can be tested with this script:
VG=vg1
lvremove -f $VG/origin
set -e
lvcreate -L 2143289344b -n origin $VG
lvcreate -n snap -c 8k -L 2304M -s $VG/origin
dd if=/dev/zero of=/dev/$VG/snap bs=1M count=2044 oflag=direct
The bug happens when these two conditions are met
* origin size is divisible by (chunk_size/16) - so that the last
metadata area is filled completely
* the miscalculated snapshot metadata size is divisible by extent size -
so that there is no padding to extent boundary which would otherwise
save us

While stripe size is twice the physical extent size,
the original code will not reduce stripe size to maximum
(physical extent size).

Switch to use ext2 to make it usable on older systems.
Previous test has not been able to catching problem.
Multiple tests are now put in.
FIXME: validate what is doing kernel target when
the header is undeleted and same chunk size is used.
It seems snapshot target successfully resumes and
just complains COW is not big enough:
kernel: dm-8: rw=0, want=40, limit=24
kernel: attempt to access beyond end of device
When chunk size is different it fails instantly.
For checking this with lvm2 and this test case use this patch:
--- a/tools/lvcreate.c
+++ b/tools/lvcreate.c
@@ -769,7 +769,7 @@ static int _read_activation_params(struct
lvcreate_params *lp,
lp->permission = arg_uint_value(cmd, permission_ARG,
LVM_READ | LVM_WRITE);
- if (lp->snapshot) {
+ if (0 && lp->snapshot) {
/* Snapshot has to zero COW header */
lp->zero = 1;
lp->wipe_signatures = 0;
---
and switch to use -c 4 for both snapshots
When read-only snapshot was created, tool was skipping header
initialization of cow device. If it happened device has been
already containing header from some previous snapshot, it's
been 'reused' for a newly created snapshot instead of being cleared.
Skip over LVs that have a cache LV in their tree of LV dependencies
when performing a pvmove.
This means that users cannot move a cache pool or a cache LV's origin -
even when that cache LV is used as part of another LV (e.g. a thin pool).
The new test (pvmove-cache-segtypes.sh) currently builds up various LV
stacks that incorporate cache LVs. pvmove tests are then performed to
ensure that cache related LVs are /not/ moved. Once pvmove is enabled
for cache, those tests will switch to ensuring that the LVs /are/
moved.
Test currently fails with make check_cluster - so uses 'should'

Remove 'skip' argument passed into the function.
We always used '0' - as this is the only supported
option (-K) and there is no complementary option.
Also add some testing for behaviour of skipping.
