Rootfs on usb attached drive

[meesha]

Hello. I have a problem with moving root partition to another drive. I use dedicated ubuntu server image and boot from sdcard. It works fine. Now, I want to move the rootfs to another drive. So I clone the 5th partition to an ssd drive in usb3.0 enclosure (create partition, mkfs.ext4 and so on), and then change the extlinux.cfg append option to direct the kernel to proper partition.

Now, upon boot, it looks like it starts fine, and at some point the led on the enclosure blinks once. Then the system seems to hang - green led is on, and the red is in constant “heartbeat” mode.

Am I missing something? I used the same procedure with my RPis, and it worked fine. I don’t want to stick to sdcard only. Please help.

P.S. I tried to connect the drive with an external powered hub and nothing changes, so I think I ruled out possible undervoltage.

I think I got it. Armbian booted fine from sdcard + usb attached drive. Looks like I asked myself for trouble by using that distro.

Moving file system to NVME procedure?

From what I understand I will still have to have the bootloader and kernel on an EMMC or uSD So what’s the correct way to move the filesystem to an NVME? Is there a builtin script for this? Update grub? I was hoping to just change a mount point in fstab but root is not even mounted from fstab. Thanks

It is the same. Go through whole topic.

Thanks for replying. I know I have to use the sd card for booting and wanted similar solution for myself. I see that - what I didn’t check - you enabled initrd.img and that made a difference. So it is more like of a kernel configuration issue, but Armbian is better in this regard. I just ditched bubuntu, and all is good.
