Installation on RPi2

Hi,

I have downloaded omv_3.0.51_rpi2_rpi3 image (and also tried with omv_3.0.41_rpi2_rpi3) from Sourceforge.

I run these commands on my Ubuntu box:
gunzip omv_3.0.41_rpi2_rpi3.img.gz
sudo dd bs=4M if=omv_3.0.41_rpi2_rpi3.img of=/dev/sdb

Then I insert SD card to my RPi and run it. The problem is, it seems it does start to boot, but there is no signal on the screen. I can see an IP assigned to RPi on my Mikrotik router, but cannot ping it and nmap shows all ports are closed.

What am I doing wrong? Probably there is some stupid error, but I cannot find a solution. BTW, I tried to install original Raspbian Jessie, and it is working nice.

It has been used for Raspbian on the same RPi and I just reformatted it (actually re-dd-ed it). So I assume SD card is OK.

I will try to reformat the SD card with FAT32 and with 1M parameter again.

I know. Actually, I just wanted to delete partition table in case Ubuntu has some stupid problems with SD card. I will try another SD card, but the problem is - when I dd the image again and remount the SD card, I can see three partitions and data on them...

Well, it seems SD card adapter has been faulty. I changed it, and now it works.

Weird.
