be94410446 tests: fsadm test continue after fs repair
Test case where filesystem has been corrected via fsck.
In such case fsck returns '1' as success and should be
handled in a same way as '0' since fs is correct.

6226512ad2 get dev size when setting pv device
In some cases the dev size may not have been read yet
in set_pv_devices().  In this case get the dev size
before comparing the dev size with the pv size.

f3b723cd8d pvscan: rework to improve PVs without metadata
Restructure the pvscan code, and add new temporary files
that list pvids in a VG, used for processing PVs that
have no metadata.

The new temp files, in /run/lvm/pvs_lookup/<vgname>, allow a
proper pvscan --cache to be done on PVs that have no metadata.
pvscan --cache <dev> is only supposed to read <dev>, but when
<dev> has no metadata, this had not been possible.  The
command had to fall back to scanning all devices to read all
VG metadata to get the list of all PVIDs needed to check for
a complete VG.  Now, the temp file can be used in place of
reading metadata from all PVs on the system.

677f829e54 add label_read_pvid
To read the lvm headers and set dev->pvid if the
device is a PV.  Difference from label_scan_ functions
is this does not read any vg metadata or add any info
to lvmcache.

2c9bb67604 scanning: improve filtering control
Filtering in label_scan was controlled indirectly by
the fact that bcache was not yet set up when label_scan
first ran.  The result is that filters that needed data
would not run and would return -EAGAIN, which would
result in the dev flag FILTER_AFTER_SCAN being set.
After the dev header was read for checking the label,
filters would be rechecked because of FILTER_AFTER_SCAN.
All filters would be checked this time because bcache
was now set up, and the filters needing data would
largely use data already scanned for reading the label.
This design worked but is hard to adjust for future
cases where bcache is already set up.

Replace this method (based on setting up bcache, or not)
with a new cmd flag filter_nodata_only.  When this flag
is set filters that need data will not run.  This allows
the same label_scan behavior when bcache has been set up.
There are no expected changes in behavior.

bd272e3bce lvmcmdlib: lvm2_init_threaded
cmd context has 'threaded' value that used be set
by clvmd - and allowed proper memory locking management.
Reuse same bit for dmeventd.

Since dmeventd is using 300KiB stack per thread,
we will ignore any user settings for allocation/reserved_stack
until some better solution is find.
This avoids crashing of dmevend when user changes this value
and because in most cases lvm2 should work ok with 64K stack
size, this change should not cause any problems.

3e06061d82 cov: split check for type assignment

a17ec7e0ba dm: remove created devices on error path
DM tree keeps track of created device while preloading a device tree.
When fail occures during such preload, it will now try to remove
all created and preloaded device. This makes it easier to maintain
stacking of device, since we do not need to check in-depth for
existance of all possible created devices during the failure.

d2bdad28d1 tests: extend area covered by error target
Since 'BLKZEROOUT' streams out more block at once, at can easily
zero-out larger set of blocks after 1st. failing one.

So the test is adapted to fully 'hide' swap header under error target.

e7fff97b8d wipe_lv: use BLKZEROOUT when possible
Since BLKZEROOUT ioctl should be supposedly fastest
way how to clear block device start using this ioctl
for zeroing a device. Commonly we do zero typically
small portion of a device (8KiB) - however since we now
also started to zero metadata devices, in the case
of i.e. thin-pool metadata this can go upto ~16GiB
and here the performance starts to be noticable.

0fe58fc54f bcache: fix busy loop with too many errors
When bcache tries to write data to a faulty device,
it may get out of caching blocks and then just busy-loops
on a CPU - so this check protects this by checking
if there is already max_io (~64) errored blocks.

41f9e372c0 bcache: fix waiting problem for completed IO
Call _wait_all() which does check whether there is still
some pending IO before sleep. Otherwise it may happen
our submitted IO operations have been already dispatched
and this call then endlessly waits for IO which are all done.
This can be reproduced when device returns quickly errors
on write requests.
