9539ee8098 lvmetad: set disabled flag in lvmetad if duplicate PVs are found
When devices are being scanned, if duplicate PVs are seen,
tell lvmetad to set its disabled flag because of duplicate PVs.

07c1694ff5 tests: update aux raid support
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).

d1ecbfa52d lvcreate: improve --chunksize support for cached volume.
Support parsing --chunksize option also when converting.
Now user can use cache pool created with i.e. 32K chunksize,
while in caching user can select 512K blocks.
Tool is supposed to validate cache metadata size is big enough
to support such chunk size. Otherwise error is shown.

d3b15674df lvcreate: check for lv type and created segtype
When creating LV - in some case we change created segment type
(ATM for cache and snapshot) and we then manipulate with
lv segment according to 'lp' segtype.
Fix this by checking for proper type before accessing segment members.

This makes command like:

lvcreate --type cache-pool -L10 vg/cpool
lvcreate -H -L10 --cachesettings migtation_threshold=10000  vg/cpool

to pass since now tool correctly selects default cache policy.

a2d2a61339 pvscan: autoactivation should ignore some VGs
pvscan autoactivation has its own VG processing implementation,
so it can't properly handle things like foreign or shared VGs,
so make it ignore those VG types (or errors from them) as best
as possible.

Add a FIXME stating that pvscan autoactivation must really be
moved to the standard VG processing by calling process_each_vg
to do activation once the scanning / cache update is finished.

3c53acb378 metadata: fix segfault when filters reject devices
Checking for devices uses is_missing_pv() to check
if there is a device for the PV.  is_missing_pv()
is based on the MISSING_PV flag, which does not
always correspond to !pv->dev.  When using lvmetad,
a command like:

pvs --config 'devices/filter=["a|/dev/sdb|", "r|.*|"]'

will cause a number of PVs to have NULL pv->dev, but
not the MISSING_PV flag.  So, NULL pv->dev needs to
also be checked.

2bb33aaf55 udev: rules: remove mpath from 10-dm.rules, superseded by 11-dm-mpath.rules (mpath>=0.6.0)
Multipath 0.6.0 contains new 11-dm-mpath.rules which supersede the rule
that was in 10-dm.rules. The 11-dm-mpath.rules are also more complete,
fixing several other issues. Using the new 11-dm-mpath.rules from
multipath-tools >= 0.6.0 is strongly recommended for proper
DM multipath functionality!

Probably not worth mentioning "segments" here, just state that devices
for an LV can't be all found during the check - it's less mysterious for
user then:

9d976c0002 metadata: log warning instead of error if device not found while checking used and assumed devs
When checking assumed PVs against real devices used for LVs and if
there's no device assigned for an assumed PV (e.g. due to filters),
do log_warn instead of log_error and continue checking LV segments
and associated assumed PVs further, just like we do log_warn elsewhere
in this situation.

This way user will see the warning for each LV which couldn't be
checked completely against real PVs used. Before, we logged only
the very first occurence of missing device for an LV in a VG and we
returned from the function doing this check for all the LVs in VG
immediately which may be a bit misleading because it didn't tell
user about all the other LVs and whether they could be checked
or not.

For example, we have this setup:

[0] fedora/~ # pvs
  PV         VG     Fmt  Attr PSize   PFree
  /dev/sda          lvm2 ---  128.00m 128.00m
  /dev/vda2  fedora lvm2 a--   19.49g      0

[0] fedora/~ # lvs -o+devices
  LV   VG     Attr       LSize   Devices
  root fedora -wi-ao----  19.00g /dev/vda2(0)
  swap fedora -wi-ao---- 500.00m /dev/vda2(4864)

Before this patch (only the very first LV in a VG is logged to have a
problem while checking used and assumed devices):

[0] fedora/~ # pvs --config 'devices/filter=["a|/dev/sda|", "r|.*|"]'
  WARNING: Device for PV Qcxpcy-XgtP-UD3s-PmG0-qLyE-Z0ho-DYsxoz not found or rejected by a filter.
  WARNING: Device for PV Qcxpcy-XgtP-UD3s-PmG0-qLyE-Z0ho-DYsxoz not found or rejected by a filter.
  Couldn't find device for segment belonging to fedora/root while checking used and assumed devices.
  PV         VG     Fmt  Attr PSize   PFree
  /dev/sda          lvm2 ---  128.00m 128.00m
  [unknown]  fedora lvm2 a-m   19.49g      0

With this patch applied (all LVs where we hit problem while checking
used and assumed devices are logged and it's warning, not error):

[0] fedora/~ # pvs --config 'devices/filter=["a|/dev/sda|", "r|.*|"]'
