http://stackoverflow.com – System Debian 6 / 32 bit VSphere Goal Resize main partition to utilize all resources now available. Issue I increased the disk space on my vm instance in Vsphere however I'm new to Linux and can't figure out how to: See this new available space (an extra 13 gigs) Figure out which partition is the main partition (I believe it's /dev/sda1) Figure out how to resize it up to the full 20g now available Figure out if I have offending files that are using up all my disk space in the first place Troubleshooting fstab # <file system> <mount point> <type> <options&g (HowTos)
