Raspi 4 file server disappointing transfer speed, degradation and segfaults

Fri Oct 11, 2019 11:54 am

Hello,

So I had an Orange PI PC for many years with a 2TB Seagate HDD attached to it. The HDD supports USB3, the Opi didn't.
My PI4 currently runs the latest and greatest:

Linux raspi4 4.19.66-v7l+ #1253 SMP Thu Aug 15 12:02:08 BST 2019 armv7l GNU/Linux

Code: Select all

No LSB modules are available.
Distributor ID:	Raspbian
Description:	Raspbian GNU/Linux 10 (buster)
Release:	10
Codename:	buster
As a test I started copying over the internet a 100GB image file. The transfer starts ok so-so I get 3MBytes/sec for about 2 hours then the performance starts to degrade to 4-500Kbytes/s according to iotop and my kernlog full of segfaults:

This is VERY disappointing, I was expecting improved performance from the Raspberry PI 4 not unreliability and degradation and no it is not a power supply issue since I power it from a PSU which can easily do even 5Amps on 5V rail and have no power warnings anyway and not an internet issue since I get 77mbit/s with speedtest-cli :(

Re: Raspi 4 file server disappointing transfer speed, degradation and segfaults

And on top of this the CPU temperature with 2 alu blocks on it in idle is around 50C, the OPI was on 40C.
I start feeling this upgrade does not worth it, however I get slightly better VPN performance, while with the opi the tunnel tops out around 30-40mbit, the raspi4 can do 60-70mbit/s in tun mode but that also comes down to the fact that openvpn only use 1 core so higher clockspeed = higher vpn throughput.

And on top of this the CPU temperature with 2 alu blocks on it in idle is around 50C, the OPI was on 40C.
I start feeling this upgrade does not worth it, however I get slightly better VPN performance, while with the opi the tunnel tops out around 30-40mbit, the raspi4 can do 60-70mbit/s in tun mode but that also comes down to the fact that openvpn only use 1 core so higher clockspeed = higher vpn throughput.

There has been several updates to Raspbian Buster, one related to USB3, since release in June 2019:

Code: Select all

sudo apt update
sudo apt full-upgrade
sudo reboot

Regards speedtest-cli has proved unreliable, therefore on internal LAN iperf3 is a better tool.

Re: Raspi 4 file server disappointing transfer speed, degradation and segfaults

klesk,
This is VERY disappointing, I was expecting improved performance from the Raspberry PI 4 not unreliability and degradation
That is a sad case.

You have run out of memory and the Linux kernel SLUB memory allocator has given up. See end of error messages.

That is a bug in the Linux kernel. It's a bit rash to blame the Raspberry Pi for problems in the Linux kernel. Linux is full of such bugs and they can crop up on any machine, especially when doing extreme things like moving 100GB files.
Memory in C++ is a leaky abstraction .

Ah silly me, I should've noticed that there is even a later upgrade as you suggested. However sadly even after upgrading to:

Linux raspi4 4.19.75-v7l+ #1270 SMP Tue Sep 24 18:51:41 BST 2019 armv7l GNU/Linux

The problem still persist. Somehow I don't trust in these "magical" upgrades :( I hope devs will look into this.

It's crying something about net_rx and memory, I have the model with 1GB memory but according to htop it only using 170MB/1GB.

So no the upgrade did not help at all :(

Re: Raspi 4 file server disappointing transfer speed, degradation and segfaults

Sat Oct 12, 2019 3:20 pm

You have to find the bottle neck in the long string of connections and eliminate that route.

If you want to measure the transfer rate, you need to perform it over a network where you have control over each type of connection and know that the proper cable, wireless link, switch, router, etc. is as fast as the Pi or faster. Putting a cat 4 cable into 1 Giga bite network will adversely affect all traffic on that leg of the network. You have no control beyond your router's connection to your ISP.

Ah silly me, I should've noticed that there is even a later upgrade as you suggested. However sadly even after upgrading to:

Linux raspi4 4.19.75-v7l+ #1270 SMP Tue Sep 24 18:51:41 BST 2019 armv7l GNU/Linux

The problem still persist. Somehow I don't trust in these "magical" upgrades :( I hope devs will look into this.

It's crying something about net_rx and memory, I have the model with 1GB memory but according to htop it only using 170MB/1GB.

So no the upgrade did not help at all :(
On this very forum I learned from someone--not a moderator or Raspberry Pi employee--an often applied computer science wisdom: Memory leaks are not a problem because you get all the memory back again after rebooting.

Do you have full disk encryption enabled? What about LVM? Are you using JFS or XFS? If yes to any of the above, does the problem persist when using EXT4 directly on a disk partition?

I set a 4B up as a file server, originally with a 32TB BTRFS disk pool. The only minor problem I noticed was with the btrfs utility in Raspbian Buster. This was resolved by copying over the binary executable from the previous version of Raspbian. For reasons unrelated to the Pi itself, I have since moved that drive pool to a different machine and now have only a single drive attached to the 4B. It backs up other systems with rsync and seems stable.

Although I'm using the stock 32-bit LPAE kernel in Raspbian, it is possible your problems would go away with the 64-bit experimental kernel. In my opinion LPAE doesn't make much sense on the 1GB model of Pi 4B anyway.

Re: Raspi 4 file server disappointing transfer speed, degradation and segfaults

Yes I forget to tell about that I do have full disk encryption and I do use XFS and I don't want to switch any of it. This seems a pure software issue for me which should be fixable from the firmware or linux kernel.

So Today for example managed to reset the PI4 again with just copying a lot of small files:

Again I see like 90MB used out of 1GB in the htop. I have read that completely disabling the GPU is not possible because that's responsible for the boot but since I don't need it at all (i use this pi headless for server) maybe I could even gain more memory by allocating the least for the GPU?

I had plenty of x86 P4 older boxes with only 1-2gb ram as fileservers and never had memory problems because fileserver usually is just an IO bridge between the hdd and network card and these days all CPUs support AES encryption in hw so that shouldnt be a big overhead either.

We don't have HW encryption support in the SoC, so there is an added overhead there.

Not sure about the crash, IIRC there are known problems with full disk encryption, but would have no idea who to flag up for that one.

It performs very well on my Pi with USB 3.0 HDD.

klesk,
This seems a pure software issue for me which should be fixable from the firmware or linux kernel.
You make it sound so easy. It's only software right?

Let's not forget that there is 10 million lines of code between you and the hardware in just the Linux kernel alone. Written by thousands of people over decades.

You are likely to be the only person in the world using XFS and full disk encryption on an ARM or Raspberry Pi and whatever unique drivers it has. It's a really odd thing to do. So whatever combination of things that triggers that bug might never have been seen before and be hard to track down.

I guess somebody could dedicate an unknown amount of time tracking down the problem and fixing for you. Likely they have other things to do.

If it were me, if I really needed that and because I'm curious, I'd start experimenting with isolating parts. Do the test with XFS and no encryption, with encryption and some other FS, with different storage media, different kernel versions and builds.

In my opinion XFS with full-disk encryption on ARM is likely not that unusual; however, XFS with full-disk encryption under a 32-bit LPAE kernel running on an ARM processor with only 1GB memory that doesn't support hardware AES might be.

Software and hardware teams that don't pay attention to bug reports because most users don't do that eventually end up with products unfit for any purpose. Just like a rare disease is an excellent opportunity for medical researchers to learn about human physiology in a way that improves healthcare for everyone, so do rare bugs provide an opportunity to learn about things that can be improved in a computer system.

Although everyone with a Pi 4B is currently running an LPAE kernel, such kernels are well known for memory management problems. Simply put, computers with more than 2GB of RAM generally run in 64-bit mode where it is much easier for the kernel to allocate and deallocate memory in a sensible way.

Is it possible that XFS with full-disk encryption leads to catastrophic memory fragmentation when running on an LPAE kernel rather than a leak? I would suggest trying the experimental 64-bit kernel first to see if the crashes go away. Whether the 64-bit kernel helps or not, it would be nice to keep the present thread updated with any new information.

yeah if you drink coffee and it makes your eye hurt, then you just take the spoon out of the cup first. Before you complain about a potential issue... try to isolate what is causing your issue.

ejolson,

Perhaps.

I don't think we should be so quick to lay blame on any of the devs involved here.

As a practical matter, reproducing and fixing bugs is a huge lot or work. In that avalanche of bugs that all software has all the time where should they put their attention first? It kind of makes sense to start with the ones that cause most people to shout loudest first. It's not as if bugs and security issues are not being fixed in Linux and other systems all the time.

As users of software that is free, Free, and open source we have a responsibility to roll our sleeves up, put some effort in to narrow down the problem, find the appropriate developers and submit useful bug reports. Step one is that they even need to be appropriately notified. They cannot fix problems they know nothing about.

Whining about issues on a forum does not quite cut it.

Fortunately nobody is whining in this forum either, not even about people who find bugs and post crash reports.

This particular bug appears reproducible and so perhaps debuggable. As no special hardware other than a Raspberry Pi is involved, it could represent a deeper problem with the Linux kernel that is worth investigating. I'm not suggesting any particular person do the work, just that the bug may be interesting enough to lead to improvements for everyone in the end. On the other hand, it could turn out to be something boring related to LPAE kernels.

Perhaps "whining" is putting it the wrong way.

Point is whoever maintains whatever piece code that has the bug in question is unlikely to be reading this forum.

The question then is, given that this seems to be reproducible, how do we pin it down further, how do we find the appropriate maintainer to raise a bug report for, how do we create a meaning full bug report for them, what is the correct channel?

Having been through this, not with the kernel but other open source projects, I know it can be a long road. Sometimes with happy results. Sometimes not so much, for example I bug I reported in the a widely used and important node.js module in 2011 is still a problem. Despite extensive investigation, discussion and further reports by others:

And btw about the speeds you are right if I do hdparm -tfT on the internal crypt device I get about 83MB/s, on the physical drive itself 120MB/s so there is a loss however even a 100mbit link can be served with a hdd doing 12.5 MB/s and what I noticed is the transfer starts off with 3mbit/s then degrades down to kbytes/s due to these segfaults. I don't care if I have to switch encryption or go from xfs to ext4 just solve the problem.

So what FS would you recommend then inside? EXT4?

Adiantum I don't see this in my cryptsetup:

Yes, by default, Adiantum is not available under Raspbian. But without hardware-accelerated AES, the overall performance is far from ideal.

The default ext4 is recommended. At least I don't have any crypto or filesystem related performance or stability issues on my Pi4.

In general, I recommend ZFS everywhere 64b, but for 32b systems I usually go for XFS. I've lost data on all of ext[234], butterfs is a joke, and ReiserFS has several issues.

Software and hardware teams that don't pay attention to bug reports because most users don't do that eventually end up with products unfit for any purpose. Just like a rare disease is an excellent opportunity for medical researchers to learn about human physiology in a way that improves healthcare for everyone, so do rare bugs provide an opportunity to learn about things that can be improved in a computer system.
So, which bug from this list would you like us to start with? Bearing in mind there are about 12 SW guys at Raspberry Pi, most working on new product, some with no kernel experience at all.

https://github.com/raspberrypi/linux/issues


Worth noting that ANYONE can investigate this and many of the other bugs in that list. All the source is open, Raspberry Pi's are cheap and easy to get hold of. Amount of people who do? Not many. And many of those people would be starting from exactly the same start point as any of us here - I'm just taking a look at an encrypted swap file issue (might be the same as this one), but I have never looked at anything like this before. Could take me a week just to get to grips with what is going on, that's if I think it's worth the time, as the use case is tiny, when there are so many other bugs that affect so many more people that ought to be looked at first.

This maybe a slight aside, but as a business application developer I've no idea how to even start on anything like investigating/debugging a problem in linux/driver/overlay.

Is there any sensible documentation out there which can take someone who "can code" from knowing nothing about the internals of linux to being able to get under the covers of it and not just be restricted to writing applications on top of it?

See the Linux kernel repository. It has documentation:
https://github.com/torvalds/linux/tree/ ... umentation

I have no idea how far that might get one.

Read the book: https://lwn.net/Kernel/LDD3/

Get in touch with the maintainers of any subsystem you are interested in.

Other than once creating a device driver for a simple thing it's all too much for me.

Ok so following:

http://longsteve.com/wiki/index.php/USB ... spberry_Pi

I have recrypted the drive with:

cryptsetup --verify-passphrase luksFormat /dev/sda1 -c aes -s 256 -h sha256

and used EXT4 inside as suggested and guess what happened?

It solved absolutely nothing, I wasted almost 2 days copying the data off to do this and now we are back to square one with segfaulting, great :((((((

This adatrium you suggested I would like to try but I can't find a single tutorial on it how to do and it seems it not even in the raspbian kernel.

Ok so following:

http://longsteve.com/wiki/index.php/USB ... spberry_Pi

I have recrypted the drive with:

cryptsetup --verify-passphrase luksFormat /dev/sda1 -c aes -s 256 -h sha256

and used EXT4 inside as suggested and guess what happened?

It solved absolutely nothing, I wasted almost 2 days copying the data off to do this and now we are back to square one with segfaulting, great :((((((

This adatrium you suggested I would like to try but I can't find a single tutorial on it how to do and it seems it not even in the raspbian kernel.
So you've got somebody to help you a bit, and your strategy to get said person to take time out of his day help you for free is to be melodramatic and guilt trippy? Ok.

I'm sorry to hear that you've got problems, by the way. Take a look at the Github page to get you started:
