Hi folks :-)
after assembled a new hw (xeon, ich10 controller with 5 disks of 2Tb wd -
radi5) I have slow write performance:
20Mb/s :-(((
dd if=/dev/zero of=/share/raid/1Gb bs=1024M count=1
1+0 records in
1+0 records out
1073741824 bytes (1.1 GB) copied, 48.7203 s, 22.0 MB/s
I repeated same test also creating a 10Gb file.. same results..
write speed is better:
dd if=/share/raid/1Gb of=/dev/null
2097152+0 records in
2097152+0 records out
1073741824 bytes (1.1 GB) copied, 1.82054 s, 590 MB/s
20Mb/s is a disk/controller problem or controller can't do better?
hw is new, I already check all disks..
thanks!
Pol

Using a write block size of 1GB with dd causes the entire file to be
buffered to RAM before being flushed to disk. To prove the point, I
just ran your test against a single SATA disk with an XFS filesystem.
XFS is is optimized for large files.
$ dd if=/dev/zero of=./test bs=1024M count=1
1+0 records in
1+0 records out
1073741824 bytes (1.1 GB) copied, 139.895 s, 7.7 MB/s
The same test using a *sane* block size of 4KB:
$ dd if=/dev/zero of=./test bs=4096 count=262144
262144+0 records in
262144+0 records out
1073741824 bytes (1.1 GB) copied, 15.0732 s, 71.2 MB/s
10x decrease in performance due to the insane 1GB block size.
The machine I ran this test on is old, having only 384MB RAM and a
Sil3512 PCI SATA-I controller. The disk is a WD Blue 500GB 7.2K. Using
the 1GB block size ate over 800MB of swap out of 1GB before the buffer
was flushed. This massive buffering is what murders performance here.
Repeat your test using a 4KB block size and post the results.
Know your tools Pol.

Pretty poor. CentOS 5, Intel ICH10, md RAID 6 over 5 7200rpm 1TB drives,
then LVM, then ext3:
# dd if=/dev/zero of=test bs=4096 count=262144
262144+0 records in
262144+0 records out
1073741824 bytes (1.1 GB) copied, 2.5253 seconds, 425 MB/s
And there's a badblocks running on another drive also on the ICH10.
Having said that, I think mine's wrong too, I don't think my array can
really manage that much throughput. We should both be using more
realistic benchmarking tools like bonnie++:

And I should think of a command line options so I don't get all those +
signs. Never mind, the above shows 40-80MB/s for writes, 70-200MB/s for
reads, which is not too bad even if it's not great.
Hang on. You aren't trying to benchmark your array just after creating
it, while it's still doing its initial sync, are you?
Cheers,
John.

Or simply pass the correct flags to dd — like oflag=direct, which will
make it do non-buffered writes.

That's still not realistic:
# dd if=/dev/zero of=test oflag=direct bs=4096 count=262144
262144+0 records in
262144+0 records out
1073741824 bytes (1.1 GB) copied, 117.434 seconds, 9.1 MB/s
Because this time we're doing a read-modify-write for every 4K block, or
at least a write for every 4K block. I can fix it up again to work in
stripe size amounts:
# dd if=/dev/zero of=test oflag=direct bs=1572864 count=683
683+0 records in
683+0 records out
1074266112 bytes (1.1 GB) copied, 18.3198 seconds, 58.6 MB/s
But it's still not realistic because real I/O does use buffers and
doesn't work in magic sizes, so we should be using a more realistic
benchmarking tool like bonnie++.
Cheers,
John.

Of course :)
But at 4K speed, this is actually the speed of your array.

Buffers is one thing; flushing to disk after a certain block size
another, and that happens quite often, depending on workload.

Honestly, I don't find bonnie++ a realistic tool. fio is a much better
one; bonnie is quite old and inflexible.

In addition to the other comments so-far, are these drives WDC EARS
drives?
What's the output of
hdparm -i /dev/sda
If it's something like
Model=WDC WD20EARS-00MVWB0, FwRev=50.0AB50, SerialNo=WD-WMAZ20098633
^^^^
then it has 4KB sectors.
If so, then you'll have to make absolutely sure the partitions are aligned
on a 4KB boundary.
What does the output of
sfdisk -d /dev/sda
look like? (where /dev/sda is one of the disks on your array)
The start of each partition ought to be divisible by 64 evenly for optimal
results.
Gordon

I'm not sure of the reasons, but O_DIRECT doesn't work with dd quite the
way one would think, at least not from a performance perspective. On my
test rig it yields an almost 10x decrease, much like using insane block
size. It may have something to do with write barriers being enabled in
XFS on my test rig, or something similar. This system is running
vanilla 2.6.38.6 with Debian Squeeze atop. Using O_DIRECT with dd with
2.6.26 and 2.6.34 yielded the same dd O_DIRECT behavior in the past.
$ dd if=/dev/zero of=./test bs=4096 count=262144
262144+0 records in
262144+0 records out
1073741824 bytes (1.1 GB) copied, 15.0542 s, 71.3 MB/s

Then you have multiple problems causing poor performance. Now is the
time for you to post your hardware configuration, drive model
number(s), mdadm config, and filesystem. You should have done all of
this in your initial post.
You've been on this list long enough to have known of the WD Green
sector alignment issue and avoided it, and to know better than to run
performance tests while an array is still in its initial sync. Thus I
initially assumed your problem was merely the insane dd block size.

Ah OK, yes I agree with you there, but my general point remains: dd
might be OK for producing one very specific metric in some cases, but
that will not give a realistic impression of real use performance, so we
should be using a more realistic benchmarking tool.
Cheers,
John.

hello and sorry for the late :-(
now is a resync in progress, I can't stop it. Try /usr/share/mdadm/checkarray
-x md0 but nothing..
fs is ext3 (done less 10 days ago)

when I wrote a post there was not resync in progress..

Hello again :-)
I removed all partitions of my disks and do:
dd if=/dev/zero of=/dev/sdb bs=512 count=1 for all disks..
next, I created a new partition (non-fs data) starting of 64 like below (for
every devices)
fdisk -lu /dev/sdb
Disk /dev/sdb: 2000.4 GB, 2000398934016 bytes
255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xd2017c41
Device Boot Start End Blocks Id System
/dev/sdb1 64 3907029167 1953514552 da Non-FS data
created a new raid5 array:
mdadm --create --verbose /dev/md0 --level=raid5 --raid-devices=5 /dev/sdb
/dev/sdc /dev/sdd /dev/sde /dev/sdf
cat /proc/mdstat
md0 : active raid5 sdf[5] sde[3] sdd[2] sdc[1] sdb[0]
7814051840 blocks super 1.2 level 5, 512k chunk, algorithm 2 [5/4]
[UUUU_]
[>....................] recovery = 0.3% (6625324/1953512960)
finish=971.1min speed=33411K/sec
Now, I've 5 identical disks (2Tb WD)
I've to wait rebuilding time after do new tests performance.
The procedure that I've done is correct?
thanks! :-)

Why did you create partitions? The whole point of zeroing the first 512
bytes was to *eliminate* all the partitions...

And now you create your array without using partitions...

You created aligned partitions on all disks, and then did not use those
partitions...

No, you did not. It seems you merged bits and pieces from each array
creation method. The array may still function properly. I've never
tried what you've done here. Maybe others have the correct answer.

Follow the post of Erwan Leroux, he advise creare a new partition with non-fs
data :-/

I never used the whole disk in my raid, so maybe my procedure is not
useful in this case,
but i think if you create partitions, you should create the array using them,
using the following command mdadm --create --verbose /dev/md0
--level=raid5 --raid-devices=5 /dev/sd[bcdef]1 --metadata 1.2
i can't recall where i see why to specify this metadata level but in
my case the default was not 1.2 so i had to.
When the rebuild is done and a filesystem set , run this command dd
if=/dev/zero of=/some/dir/test.dd bs=4096 count=2621440
to actually test the performance of the raid.

What hard drive offers a sustained data rate of 425 MB/s or even half that?

"md RAID 6 over 5 7200rpm 1TB drives" does? :) At least half that - easily.
But still, the result posted is very much inflated, they forgot the "conv=fdatasync" option, so mostly benchmarking the FS cache in RAM.

425 MB/s / 3 spindles = 142 MB/s per spindle
That's not poor, it's excellent. Which drives are these? WD Black,
Seagate, Hitachi?

Gentlemen, we've been round this loop before about 10 days ago. Pol's 20
MB/s was poor because he was testing on an array with unaligned
partitions and a resync was running, my 425 MB/s was a bad test because
it didn't use fdatasync or direct and I said dd was a bad test anyway,
etc etc.
Cheers,
John.

This is purely file cache performance you have measured, nothing else.

Using a huge blocksize (anything greater than 1/10th ram) isn't terribly
realistic from an actual application point of view in *most* cases. A
few corner cases maybe, but not in most cases.
Testing on a rebuilding array gives you a small fraction of the
available bandwidth ... typically you will see writes (cached) perform
better than reads in these cases, but its not a measurement that tells
you much more than performance during a rebuild.
Unaligned perform is altogether too common, though for streaming access,
isn't normally terribly significant, as the first non-alignment access
cost is amortized against many sequential accesses. Its a bad thing for
more random workloads.

> etc etc.
dd's not a terrible test. Its a very quick and dirty indicator of a
problem in the event of an issue, if used correctly. Make sure you are
testing IO sizes of 2 or more times ram size, with sync's at the end,
and use date stamps to verify timing.
bonnie++, the favorite of many people, isn't a great IO generator. Nor
is iozone, etc. The best tests are ones that match your use cases.
Finding these are hard.
We like fio, as we can construct models of use cases and run them again
and again. Cached, uncached, etc. Makes for very easy and repeatable
testing.

Of course the 425 number is higher than real world. But this is the dd
"test" method for which many post results, so the number is still
somewhat valid for very coarse comparison purposes among systems. A
10GB run would have been better than 1GB obviously.
The Linpack benchmark is very similar to dd in this regard. It's a
horrible measure of supercomputer performance, but it's what everyone
uses. It's what allows US Government labs to go to Congress with and
say "The Chinese have passed us in the Supercomputer race. We need more
money to take the lead". (And, stupidly, Congress gives them the money)

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.

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^^

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.

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

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!

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.

hello and sorry for the late :-(
now is a resync in progress, I can't stop it. Try /usr/share/mdadm/checkarray
-x md0 but nothing..
fs is ext3 (done less 10 days ago)

when I wrote a post there was not resync in progress..
