ReadyNAS internal flash/USB
What is the internal USB and/or flash structure? How does the boot process work? Here is what read from small net builder review abut 626x : 256 MB USB module with Phison USB 3.0 controller and Tos...
The ReadyNAS used syslinux for booting, and the syslinux boot data is on the flash. But in normal mode, that boot sends it to the OS partition of the drives for the actual booting. Other modes either put an image from flash into RAM and boot that or boot a USB device. The flash also contains a default OS image used for an OS re-install. In the case of a legacy device, the flash also includes the vpd file, which identifies your NAS type and serial number. None of your personal or configuration data is stored in flash -- it's all on the drives.
Thanks. It is useful.
I got the image. It does not work.
RAIDar shows the NAS status is TFTP_REQ
It was tryin gto extract rot image, but ERROR: could mount boot flash [/dev/null1] no such file or directory
command failed: mdev -s
command failed: /usr/sbin/telnetd
Sounds like you need to do a USB recovery: How-do-I-use-the-USB-Recovery-Tool-on-my-ReadyNAS-OS-6-storage-system
Sorry I was writing on cellphone.
my 628x is okay. I made an image of the internal USB and burned the image to USB flash, then boot my PC with that USB. I got the above error. I guess that is because there is no flash drive as a real readynas does.
