Re: [mh] no space on BeagleBone uSD

Don't know if it will help at all, but I have my MH setup running on a Raspberry PI which is similar to the BBB. When I originally started with MH on the PI, I had it running Raspbian on an 8GB SD card and it worked fine. I do not run an X-window, but that is mainly for performance reasons and the fact that I mostly SSH into it. I now have it running from an external hard drive with a USB IDE converter using the SD only for the initial boot. You shouldn't have to do that though. Looking at your df output (BTW, "df -h" is a little easier to read), it is showing that you are full. 94% would pretty much be considered full which is why it is telling you you are out of space. Looking at the filename for the image, it looks like it should be a 2GB image which should give you ~6GB of space for perl and MH to be installed. Is there currently anything in your home folder? Try doing a "sudo du -csh /home/" and see if it shows any space being used. Worst case you may have to get a bigger uSD card, but you still want to find out what is eating all your space. Dan B.
