Since I am using a 16G micro SD card, I wanted to use all the space. Reluctant to mess with the 1st partition, I simply created another as an 8G ext3 filesystem labelled 'p2'. On reboot I found the new partion mounted as /media/p2. Why was the partion automatically mounted? Im not complaining, just trying to understand what is happening during the boot process. If I had wanted to rezize the 1st partition from 8G to 16G how do I use Gparted safely? Can you resize the boot partion on line?
Yeah you can do a live update. Open gparted Delete the 2nd partition. Then resize the first one to use the full size. Commit the changes.
FYI, I wasn't able to resize the boot partition with GParted while booted on that partition, but it worked just fine when I moved the microSD card to a USB slot. Of course, this requires two SD cards with the OS.
I have a 64gb microSD, I had problems with fat32 limits and the image cut that to 6gb. On a windows machine I used fat32format to get it to 64gb and keep it fat32. I put the image on the card with win32diskimager. Then used another free utility paragon partition manager to resize it to 64gb. Hope this helps others.
