xanatos,
I don't reread posts in unless I try to find something. Did not realize there were more info when you updated.

I did not pay much attention to btrfs. So not sure what can be improved in the kernel or user space.

Usually I'd like to see the sys time larger in task like this. It just mean the modern Ext4 file system driver is different.

I would not worry about HDD not spinning down.
However, if you really want to keep the HDD sleeping most of the time, you can run the rootfs on USB. Take precaution such as backing up regularly, and move logs to /tmp to prolong the USB flash drive life.

Thanks for your support bodhi.
Didn't take in account this is a full Debian, was thinking on OS like Openwrt whose space requirements are more reduced.
I just bought a small usb flash drive with good performance (Samsung FIT), planning to install rootfs on it. Original firmware lacks a lot of functionality nowadays... no VPN client/server, no Zerotier... only basic usage.

I have been struggling with SMB performance and other protocols. With stock firmware you get +- 90MB/s (gigabit limit more or less) and about 30% cpu usage, pretty good for a cheap NAS. With Debian and OMV6 you get 40MB/s at most with the CPU maxed out.
I tried to fine tuning SMB with all kind of parameteres, turning flow control off and so on, but couldn't pass 50MB/s with 90%CPU.
After investigating I noticed a thing that could be relevant and is that latest kernel lacks the cryptodev module (https://github.com/cryptodev-linux/cryptodev-linux), you can check that /dev/crypto is non existant in 6.3.8 kernel, but it exists in stock firmware kernel.
I can't assure that this issue has a direct impact in SMB performance, but I think is likely to occur. Anyway, missing cryptodev module will impact in SSL and AES encryption tasks (https, webdav, vpn, zerotier, ...), as hardware dedicated crypto engine from ARMADA 38x chip is not being used.
I tried to compile module by myself but my Linux skills are limited, it seems that kernel headers are missing and MAKE throws an error. Any advice?.

This box has Armada 380 SoC, so no need to compile cryptodev. The driver used is armada-38x-crypto. Also the rootfs Debian-5.13.8-mvebu-tld-1-rootfs-bodhi.tar.bz2 is armhf. So you have all necessary parts regarding encryption tasks.
Samba performance is a different issue. This Wiki thread post about Samba tuning could be a bit old, but it's worth a try.
Note that Samba performance is also affected by the network and HDD performance. Network performance has been checked out to be optimal with this kernel. HDD performance is harder to tell in general, because each user's hardware configuration is different.

I might need to check one more thing regarding encryption tasks for this box. I forgot whether the crypto SRAM definitions are needed in the DTS for this NAS326 box.

You can either:
1. Run the fw_setenv directly from the Debian rootfs. Assuming the USB Debian rootfs is mounted at /mnt/sdb1.
or
2. Download the binpack that I provided a long time ago:
https://forum.doozan.com/read.php?3,27280
While in stock OS, you can download the following binpack so that the normal tools for use in nand installation will be available in the system. Since Dropbox use https, you can download it to an USB stick on another Linux box and copy this tarball to the stock OS (I'll upload this to my available storage here so stock wget can be used, when I can).

To issue commands from Debian, you must first run it. And for this you need to make changes to boot_env.
The original software has the commands fw_setenv and fw_printenv, but there is no command fw_saveenv (not fw_setenv). And without it, the settings in mtd are not saved.
It works via UART. But there is another thought and I think I’ll write it later.

There is no such command as fw_saveenv. To change and save envs at the same time, use fw_setenv.

I figured out what was going on.
But I don’t understand where the error is.
Original Firmware modifies the mtd1 partition and the fw_setenv command works fine.
But... The UBoot looks for parameters at a completely different address and I don’t understand why.
Start of section mtd1 - 0200000
We read the data at this address and see the data entered from the Original Firmware
We read the data from this address and see:
This address is inside mtd2 and Original Firmware (Linux) format mtd2 when loading, because it considers that an error has occurred.
The next time you boot, UBoot does not find its data and again formats this piece of memory and writes its variables there, spoiling mtd2 for Original Firmware.
Please see if you have a nand dump, I'll try to reflash UBoot to understand what's wrong

I'm not sure I understood why you need the original u-boot dump. You can boot into stock OS to do the flashing, then you can dump mtd0 on your box. It has not changed.

In my NAS326 original firmware (Linux) saves data with the fw_setenv command at 0х200000-.... (mtd1)
But U-Boot read and saves data from/to 0x420000-... (inside mtd2)
And i don't understood why.
I think, that it is a U-Boot mistake.
And and I want to install another version of it
Yesterday I installed this version (see attaching file). But it didn't change anything

RRRrrr,
With serial console connected, power up and let it boot into stock OS.
And post the entire serial console log here (or pastebin).

Re: Zyxel NAS326 Installation Instruction November 13, 2023 12:22PM |
Hi guys. I have inserted second HDD (8TB), with ext4 fs into my NAS326. Then I tried to backup data from the original HDD (8TB, ext4 ) to the new one. And I was surprised by copy speed. Speed was between 40-60MB/s when copying big files (>1TB). CPU load around 1.9.
Then I have booted to the original zyxel system and copy speed was much higher. Around 140MB/s.
I just want to ask whether you have same speeds, just to be sure that this is maximum I can get from my device.

jaro,
The HDD performance with Ext4 file system depends on a lot of factors. Usually stock OS has specific patches that never got to mainline Linux.
So first we would want to check the raw speed of the HDD
And then look (ie. google) for optimization hints that are specific for Ext4.
I only run this box with 1 HDD so never really pay attention to this topic. May be others will chime in to help.

hdparm -tT --direct /dev/sda hdparm -tT --direct /dev/sdb... and so on. To make sure there is no problem wih the kernel.

Hi bodhi,
hdpram info looks fine. There must be an other issue, but I'm not able to find it out. I will try to setup debian from scratch.

I tried 6.0.7 and 5.13.8 kernel but result is still the same. Box is running at 100% and copying is slow (~40-60MB/s; one big file).
Bodhi, it is possible to compile a older kernel from https://github.com/MarvellEmbeddedProcessors/linux-marvell repo? Maybe there are some optimizations for Marvell CPUs. Or maybe you already did it in the past.

Not likely with current tool chain. That kernel was too old.
I think your research should be on Ext4 file system, see how other people optimized it. Don't waste time trying other older kernels.
Remember that stock FW might have some customization that are not recommended (i.e. unsafe to use). A lot of time, they rely on RAID as remedy of their unsafe performance tweaks.

Hi, there seem to be here some extremely proficient users so let me ask a question before I try to Debian my after-warranty Zyxel NAS326:
It reverts to defaults on every reboot/power. I attach full dmesg but there are some worrying lines about bad blocks in NAND:
Is there anything on earth I can do to make it keep the configuration on original firmware?

The bad block 0x000005da0000 is in your stock rootfs-1. So I think the best thing to do is to force it to boot kernel-2 each time. There are 2 or 3 envs that determine what kernel will be try next time you boot. And if it fails, it will switch to the other kernel and rootfs. So since rootfs-1 is bad, you need to force it to try kernel-2.
Power up, interrupt serial console and,

Yes. But it is always riskier when you don't have serial console. Because you cannot see any problem booting up after you've made the change.
Let see if your stock OS has these set up. SSH into stock OS and

This NAS326 box has serial console header already populated with pins, so it is quite easy (no soldering needed). Here is relevant posts

I would get the CP2012 serial module converter (quite cheap on eBay). The Prolific PL3xxx also works fine.
Find one that you can order and post here, I'll check it for you.
