hello and sorry for the late :-(
now is a resync in progress, I can't stop it. Try /usr/share/mdadm/checkarray

when I wrote a post there was not resync in progress..
tell me if you need known other things, thanks

I can't see how. You dumped the entire system. Which is probably why
no one has responded until now. Never provide all this garbage. It
takes too long to sift through and grab the relevant bits, which is only
this:

This mishmash combo of drives, including two WD Green Advanced Format
drives, is likely the cause of the horrible write performance. You're
assembling the array from partitions. The partitions on the WD20EARS
drives are undoubtedly not 4KB sector aligned, causing excessive
read-modify-write cycles. See:
http://en.wikipedia.org/wiki/Advanced_Format
Repartition the Green drives with proper alignment. If you still have
issues we'll go from there. Note: Having 3 dissimilar drives in an
array is never going to be an optimally performing solution.

first of all: sorry but my english is not good :-(
In many howto I read:
"create a partition of disk and change it to "fd" code: linux raid
autodetect"
Now I re-done whole raid (I already have a backup)
I have to create a partition on sigle disk? or remove any partition and stop?

Now I re-create a new raid system with 6 disks (everyone 2Tb wd)
How do about 4Kb sector align?
thanks!

Are these indeed advanced format drives? You didn't provide model#s or
manufacturer product line. The only clue we have that they might be AF
drives is the 2048 offset you created. Unless I simply missed it.

following is how i configured advanced format drives for raid 5
i created one partition on each disk
fdisk -u /dev/sdX
# -u change the unit displayed by fdisk to sector instead of
cylinders, this way it's easier to configure
# the table partition isn't really modifier until you send the w
command, so if you messed up use the q to quit and restart
#delete first partition of the disk, repeat until you had cleared the disk
d
# create a new partition
n
# select primary parition
p
#select number one (don't know if number is important, i guess it's
means /dev/sdX1)
1
#select first sector, here is the catch, to properly align the disk, select 64
64
#select default for the last sector
<enter>
# Change type of partition
#https://raid.wiki.kernel.org/index.php/Partition_Types
#according to this link if you use the option --metadata 1.2 with
madadm --create
# it's better to use the type DA (Non-FS data) instead of FD (Linux
raid auto) but i can't found why
# you can stick to FD, it's what is i used
t
DA or FD
# commit the change so double check the setup with the p command before do it
w
Repeat the setup for each advanced format drives and you should be good
to show you the result, here is the result of fdisk -l

Why do you choose 64? One physical sector (4KiB) is 8 logical sectors
(512 B). Would any number greater or equal to 8 and evenly divisible
by 8 work as well? Are you aiming to align partition start with RAID
chunk boundaries?
Just curious.

It's 64 because it's the lowest sector that is a multiple of 4kB.
sector 63 is the lowest possible
you can see the result of that choice, using sector 64, the
corresponding cylinder is 1, so the drive is well aligned^^

I search my bookmarks to find the original source, which has some

thanks for guide :-)

Do you not recall that I explained in detail, not two days ago, why you
should not use a 1GB block size when testing with dd in this manner?
And don't do this with the raw device. The resulting numbers, no matter
how large or small, are irrelevant.
*Put a filesystem on md0* and do:
~$ dd if=/dev/zero of=/some/dir/test.dd bs=4096 count=2621440
And why on earth would you bother running this test while the array is
still building? Again, the resulting figure is worthless to everyone.

Ok.. I waiting finish rebuild and done new test:
dd if=/dev/zero of=/some/dir/test.dd bs=4096 count=2621440

Thanks for the reply. I understood that the partition must start at a
multiple of 8 512B blocks, to be properly aligned at a 4KB-sector HDD.
I just didn't know, that you couldn't go below sector 64, e.g. to
start a partition at sector 16.
