Seagate SMR drive and Current 4.0.x Kernel
TL;DR at the top:
I've had issue with a Seagate Archive 8TB SMR drive and 4.0.x Kernels. LTS kernel works well.
I recently bought a new SMR drive to replace an old raid array. It should be okay for my purposes, but I'm considering it a test.
Model Family: Seagate Archive HDD
Device Model: ST8000AS0002-1NA17Z
Serial Number: Z8405EYR
LU WWN Device Id: 5 000c50 07b37d4fe
Firmware Version: AR13
I'm using it as a single drive.
Motherboard it's connected to is:
Manufacturer: Gigabyte Technology Co., Ltd.
Product Name: B85N
Bios Version: F5
Latest Firmware, with a Intel(R) Core(TM) i5-4440S. Chipset is Intel B85 Express.
Drive appears as sda due to the cables I have. Also in the system is a msata ssd, and three other HDD in raid5.
I made a 1 partiton GPT drive of it, and formatted it with ext4
mkfs.ext4 /dev/sda1 -m 1 -L media
mke2fs 1.42.12 (29-Aug-2014)
Creating filesystem with 1953506385 4k blocks and 244191232 inodes
Filesystem UUID: e86e2cfb-e9d2-4757-8b4f-0f94c7ee3cf9
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,

[ 591.168884] ata1.00: exception Emask 0x0 SAct 0x7ffdffff SErr 0x0 action 0x6 frozen

[ 591.168906] ata1.00: status: { DRDY }Which is the NCQ commands not getting through.
At this point, the drive needs a cold start to get going again.
I did some more testing.
I could dd TB's of zeros to the /dev device, but once I started dd'ing to a file on a FS the drive would die within a few minutes.
I tried to format it with vfat just to see, and the same thing happened.
I limited the link speed to sata2 3Gbps and sata1 1.5Gbps and the same thing happened.
I disabled NCQ and the drive also died, but with a different failed command as we'd expect.
I contacted seagate and they suggested to try seatools. I couldn't get this to work on this box so I tried with a windows box I have.
Seatools for DOS was fine, but I didn't expect any errors.
I tried Seatools for Windows, this was fine also.
I formatted it with NTFS and copied over my Steamapps directory and this was fine. I copied over a further 2 times and this was fine. This was about 300GB of data and it would normally die long before this.
I put the drive back in the original box. I mounted up the NTFS partiton with NTFS-3g and this was fine. I was able to write lots of data to it with no issue.
As this was a fuse module and not in the Kernel I then suspected the Kernel. I installed linux-lts kernel, 3.14.45-1-lts, created a 1 partiton MBR drive, formatted this with ext4, and I've been rsync'ing for 12 hours now happily.
What I have not tested is the LTS kernel with a gpt partition table.
Should I report this somewhere? I'm mainly writing this as I did a lot of googling and I didn't find much, so this may be of use to people.
I haven't kept up with kernel news, but something is happening when there's a FS on the device and I start to write data to it.
The SMR drive are a funny breed of drive, some more info here on wiki, but briefly, they need to have some extra logic for recording in a vaguely similar way to a SSD.
Any thoughts on this?

Re: Seagate SMR drive and Current 4.0.x Kernel
That "smells" a lot like a problem with the drive's firmware and not linux. SMR drives cannot write data to random places but if the firmware is emulating that then it probably relies on the fs being ntfs.
Or I might be wrong and it really is a problem with linux, maybe that drive just needs some quick to operate properly.

Re: Seagate SMR drive and Current 4.0.x Kernel
I originally thought firmware but it works perfectly fine on
lts
in windows
with current 4.0.x Kernel with a fuse module
dd'ing to the device.
Otherwise I'd agree with you

Re: Seagate SMR drive and Current 4.0.x Kernel
I'm glad to hear I am not the only archlinux user having issues with a seagate 8 TB smr device. I've got them too.
I tried it with the 4.0.7-2-ARCH kernel with 1 GPT partition formatted as ext4 and got errors (with rsync and cp; I didn't tested dd) but I didn't saved their exact wording.
Now I'm trying 4.0.7-2-ARCH kernel, (with 1) GPT (partition) formated as NTFS and it seems to work with rsync. I'm going to test it with cp and dd. So your idea with the kernel seems possible to me.
If 4.0.x, GPT and NTFS works, I'll test it with my first setup (4.0.x, GPT, ext4) and LTS kernel, GPT, ext4. (And I'll post the results and errors as soon as I have them).
But with my device there seems to be another issue.
This is my smartctl output:

If you suspect NCQ, use this kernel parameter: libata.force=noncq. you could also try larger ata timeouts...
does the disk pass a smartctl -t long selftest?

Re: Seagate SMR drive and Current 4.0.x Kernel
And I tought the ubuntuusers forum would be fast. 
If the self-test was addressed to my device, I think I'll do this test during the night.
My results for 4.0.x, GPT, NTFS (formatted in Windows):
it seems to work
rsync:
sent 180,783,327,248 bytes received 4,457 bytes 42,492,262.71 bytes/sec
total size is 180,739,183,411 speedup is 1.00
cp:

5000+0 Datensätze aus
5242880000 Bytes (5,2 GB) kopiert, 52,691 s, 99,5 MB/sI am going to reformat the device as ext4, reboot and repeat this test.

By setting queue depth 1? I'd try with noncq anyway.

Re: Seagate SMR drive and Current 4.0.x Kernel
This bug report[1] might be of interest.
From some of the links in the bug report, the problem does seem to be related to kernel version. It also seems these drives may not be the best pick right now, proper detection and support for these drives is probably not the best right now and it seems they may not be the most problem free drives - follow the links in the bug report and read the q&a at serverfault.
This[2] also seems like an interesting read, it's not directly related to the problem at hand but seems quite detailed on the quirks of smr drives.

Re: Seagate SMR drive and Current 4.0.x Kernel
I was hesitant to buy the drive in the first place, but it wasn't an urgent need so I said I'd try.
FWIW, it works without issue on 3.14.

Re: Seagate SMR drive and Current 4.0.x Kernel
What does the error message look like then? You should not get "QUEUED" with NCQ disabled?
With libata.force=noncq it should show this in dmesg: NCQ (not used)
$ dmesg | grep NCQ
[ 0.740522] ata1.00: 125045424 sectors, multi 16: LBA48 NCQ (not used)If its a general timeout problem, maybe setting the appropriate `find /sys -name timeout` to a larger value?

Re: Seagate SMR drive and Current 4.0.x Kernel
@R00KIE Really thank you for your post. I was experiencing exactly the same issues like Jens (the person who created the bugreport on kernel.org in [1]).
(Disk is inaccessable until power off; even (soft) rebooting to windows didn't help). I am now testing rsync (with 100GB data).
And it failed:
rsync: write failed on "/run/media/simon/seagate/data": Read-only file system (30)
rsync error: error in file IO (code 11) at receiver.c(393) [receiver=3.1.1]With the downgrade to the LTS kernel I personally see two problems:
1. We don't know how long the LTS kernel will stay the 3.14 kernel. So what if they update the LTS kernel to a higher version with this issue?
2. For months I have been waiting for the 4.2 kernel because this kernel includes amdgpu (and I own a R9 290) so I definitely want to upgrade to 4.2.
So my personal conclusion is:
I'll finish my test and reformat the device as NTFS. The transfer speed may be worse and it's a nonfree file system, but I didn't buy this device for speeding up my system. I bought it as "data cemetery" (if you can say that in English) for my television recordings and some other not very important (but disk space eating) stuff. So I think I'll keep the standard kernel as I'll keep this device with two GPT partitions: a large NTFS one for data and another small ext4 one for testing purposes.
And I'll test it with disabled NCQ.
This is the last dmesg output:

Re: Seagate SMR drive and Current 4.0.x Kernel
I didn't see much speed difference with NTFS but that's too much if a kludge for me.
My usage is similar, it's just a partition for xbmc and plex to read from.

Re: Seagate SMR drive and Current 4.0.x Kernel
If you have the time and will to do more tests, you could also try other filesystems, although not as tested and reliable as ext4 you might want to try f2fs or btrfs.
Due to the way it works, I'd say f2fs seems a good candidate for use with smr drives. As for btrfs I think that it might also behave nicely if you tell it to assume the drive is a ssd. SMR drives and ssds seem to be somewhat similar as you can write a page/sector at a time but can only erase full blocks.
I would also make sure to test as frostschutz says, completely disable ncq for testing and see how it goes although I suspect it might not change much. On the other hand the drive should just work, even if very slowly at times, as it is a "drive managed" type of drive.
The End-to-End_Error issue might be worth looking into, it might indicate a problem with that particular drive. I suppose it would not be the cause of the big issue being discussed but might cause problems for data integrity. Someone at superuser say to have received a few dead on arrival drives so there may be some quality assurance problems with some batches of drives.

Re: Seagate SMR drive and Current 4.0.x Kernel
You are right it is kind of a kludge (what a nice word, I know it in my first language, but haven't known it in English, yet) but my television reciever is not the best one and sometimes causes filesystem errors on NTFS formated USB-devices. So I am used to copy these recordings in Windows (and run chkdsk /F before that) to other devices so it's not that bad thing that this seagate device filesystem is NTFS.

Re: Seagate SMR drive and Current 4.0.x Kernel
With linux LTS kernel, GPT, and ext4 (and still disabled NCQ) at least dd works at my system without errors, too.
I didn't test rsync and cp because my Xorg driver doesn't work with the lts kernel. But I assume they would work, too.

Re: Seagate SMR drive and Current 4.0.x Kernel
This morning I received my exchange device. The SMART error is gone. I tried it with the recent linux kernel (4.1.2-2-ARCH), ext4 and enabled NCQ. dd works for 5 GB and 10 GB, but trying it with 100 GB produces:

So even with the recent 4.1.x kernel (4.1.2-2-ARCH) ext4 is still not working. So I'll return to my solution with the two partitions (the bigger one formatted as NTFS for data and the other one formatted as ext4 for testing purposes).

Re: Seagate SMR drive and Current 4.0.x Kernel
Hi,
It looks like kernel 4+ issues with this drive are result of purely kernel bug - not drive.
Following patch on 4.0.8 allows me to successful write 7T of test data without any SATA error.
Without patch drive interface goes down after 50-150G of writes.
