This test is quite sensitive to resync speed - if the resync happens
to quickly it fails because it sees aan optimal array when it expects
a degraded array.
1000 is often slow enough but now always, so slow it down even more.
This requires reducing speed_limit_min also as kernel ignores 'max'
when speed is below 'min'.

In repair mode, raid6check will rewrite one single stripe
by regenerating the data (or parity) of two raid devices that
are specified via the command line.
If you need to rewrite just one slot, pick any other slot
at random.
Note that the repair option will change data on the disks
directly, so both the md layer above as well as any layers
above md (such as filesystems) may be accessing the stripe
data from cached buffers. Either instruct the kernels
to drop the caches or reassemble the raid after repair.

Added tests for cases when:
0 - there is no config file at all
0a - config file has no domains defined
9a - spare is in global domain
15 - spare is in global domain for $platform metadata
Test 4 pass condition changed for imsm metadata.
disk_policy only adds controller domain for imsm
when config_rules_has_path=1.
If there are any domains in config then every disk will have also
a controller domain.
As a result the array needing spares has at least
one controller domain even when it doesn't have any other
domains specified explicitly. In this case any spare in the same
controller domain matches when it has no other domains from config.
(This behaviour is different from the case when there is no paths
in config at all as array domain then is null and no spare matches)

Patch provides set of tests for On-line Capacity Expansion,

13 - On-line Capacity Expansion on two volumes
14 - Negative tests for takeover, migrations
15 - Chunk size migrations
16 - raid0 -> raid5, raid5 -> raid0 migrations
18 - takeover operations
To run particular test group, following command should be executed:
(from mdadm's source code root directory)
./test <group number>
Example:
To run On-line Capacity Expansion on one volume tests:
./test 12
Tests execution results:
- In case of test pass, "succeeded" word is printed on console
- If test is failed, "FAILED" word is printed on console
