If a disk fails and simulaneously a new array is created, a race
condition may arise because the meta data on disk doesn't reflect
the disk failure yet. This is a test for that case.

This is one more unit test for failure/recovery, this time with
double redundancy, which isn't covered by the other tests.
Signed-off-by: NeilBrown <neilb@suse.de>
This test has some randomness because it is not always deterministic
which of the two arrays gets the spare and which remains degraded.
Handle it.

Let the first created array be RAID5 rather than RAID0. This makes
the test harder than before, because everything after the first
Create has do be done indirectly through mdmon.

Linux 3.10 will allow more "--add" to be handled as "--re-add".
To be sure the tests work correctly we sometimes need to zero
the device to ensure it really is an --add that happens.

super1: reserve at least 2 chunks for reshape headroom.
reserved more space in a RAID5, so we need to update to array
sizes when reshaping.
Also make sure reshape tests we change the shape: raid5->raid1
was failing and we didn't notice.

When calling raid6check in regular scanning mode, specifiying
"autorepair" as the last positional parameter will cause it
to automatically repair any single slot failes it identifies.

In repair mode, the data block indices to be repaired were calculated
using geo_map() which returns the disk slot for a data block index
and not the reverse. Now we simply store the reverse of that calculation
when we do it anyway.

We need to set speed_limit_min accordingly, otherwise setting
speed_limit_max below 1000 will have no effect.

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.

A recent change means that devices smaller than

So we must adjust some sizes again.
Signed-off-by: NeilBrown <neilb@suse.de>
RAID1 arrays don't have a chunk size, but if you ever convert
one to RAID5 you will need at least a small one >= 4K.
So round of size to a multiple of 64K.
This only affect Create, not "--grow --size=max". The latter
is too hard and with smaller returns.
