k0rnev Posted September 23, 2018 Share Posted September 23, 2018 Hi Experts, I have a strange issue while Armbian installation to my Orange PI PC boards. So there are two SD cards with the same parameters: 1. smartbuy 8gb sdhc class 10 2. OltraMax 8gb sdhc class 10 The problem is that when I use smartbuy card I can install Armbian and it works fine. But when I use OltraMax card I can install Armbian but after first login it asks me the following: Warning: a reboot is needed to finish resizing the filesystem Please reboot the system as soon as possible Ok, I do a reboot and Orange PI PC can't boot Armbian after. Moreover as can I understand I get a boot loader (u-boot) console where I can type some commands. An interesting thing is that if I install Armbian using smartbuy card and then I make an IMG (full image) from it and write this IMG to OltraMax card so Armbian works fine from OltraMax card! So I started an investigation and collected logs from both SD cards by the following plan: 1. Write IMG (Armbian 5.59 Debian Stretch) to SD card 2. Run Orange PI PC and install Armbian 3. Reboot Armbian 4. Login Armbian and shutdown (only with smartbuy card I can do that step). Than I compared both logs and found some strange messages for OltraMax board: Picture above shows first execution logs (in compare mode), OltraMax output contains messages about a "bad MBR sector signature". Than when I installed both and did a first login using root 1234 I find another artifact: Take a look at Usage of values. Seems like smartbuy extended it's FS size while installation but OltraMax no, it's still 1GB. And OltraMax have a message I mention above (reboot for fs resizing). Than I did a restart and faced a current issue: As I understand something wrong with FS resizing on OltraMax card probably because of "bad MBR sector signatures" So can anybody heIp me? I do want to understand why it happens and find a workaround because I bought about 14 OltraMax cards for my Orange Pi PC cluster. I may attach both logs if it's needed.

I can use this cards on my phone or PC, seems like they work :) So what is a different between fake and non-fake cards? As I said if I install Armbian using card that works fine and then I make an IMG from it and install this IMG to OltraMAx cards than they works too.

Fake cards can have various issues, from being slow as hell, over corrupt sectors up to a fake size. I would format both cards completely and then follow the recommendations: https://docs.armbian.com/User-Guide_Getting-Started/#how-to-prepare-a-sd-card e.g. the testing part with h2tesw or f3 might be important..
