So i must to have 3x2T HDD to get speed up to 90 Mb/s ? And configure program RAID0 to get it?! Ve ...

I've only stated what you can get.
And you can have 3x300MB or 3x500MB hd (in raid0 configuration total capacity = sum of each drive capacity)
And you must know how to choose the hardware according to your needs.
And yes, I think solving problems is fun , and working with raid configurations is even more fun....

Hi Loboris!
I do..
1 .script_kernel.tar.gz extract to --> /media/boot/ ???

Have you extracted script_kernel.tar.gz to /media/boot ( why ??? "/media/boot/ ??? "
There was missing / in "sudo cp /media/boot/uImage_OPI-2 media/boot/uImage" it must be

sudo cp /media/boot/uImage_OPI-2 /media/boot/uImage

Copy code

but you should realy be able to know that it was the mistake.
You don't need to use sudo if you are logged in as root.

Hello Loboris!
I'm sorry a possible silly question...

I'm in Linux just a 1-2 week studying.
It is difficult to understand the error...

I think the development boards like OPI are great for learning Linux.
There are thousands of tutorials and howto's for Linux in every language. Searh with google..
Don't hesitate to ask, I'm glad if I can help.

Well, your job is really need! Thanks a lot!
But choosing OPP i hadn't any information about SATA2USB bringe on it. There are no information about it on main page

Onboard Storage

TF card (Max. 64GB) / MMC card slot , up to 2T on 2.5 SATA disk
8GB EMMC Flash

Yes, my problem is - i want to get max for low cost. Who don't want it?!
OPP idea - good, production not at all.
You had said OPP2 will have 2 Gb RAM - good, same SATA2USB - bad, very bad! It's good "client" solution only, not server.

Official images (debian-server) are not completed, 2 cores are shutdown by regular by high temp reason, NFS-server support has gone...
I havn't tested new images yet, but ~30 Mb/s is too slow for my purposes...

P.S. I have mistaken with 3x2Tb, but 3x750Mb is needed.

Hi!
I got the result:

It must be cmdline.txt

file on boot partition (eMMC or SD card) contains

root=/dev/sdXn, where /dev/sdXn is the USB drive partition (as visible from OPI) to which to boot

(for example root=/dev/sdb1)

Hi !

The script creates cmdline.txt in /media/boot directory (the directory where the 1st sd card partition is mounted).
Just reboot your OPI with USB drive connected, it should boot to USB drive.
It will look the same (you cloned your cd card), but if you run mount command in terminal, it should show that the / is mounted on USB drive (probably /dev/sda1).

Booting from USB without sd card (or emmc) is not possible (on the sd card is bootloader and u-boot, you can's see them, they are writen to the space before the 1st partition).
I will create the script for restoring the USB backup to sdcard/emmc next week.
