You do not need to mess it up, unless you are actually using all 2TB of the disk. Use gparted to shrink the existing partitions as required. On Sat, Jan 17, 2015 at 8:11 PM, jd1008 wrote: > > On 01/17/2015 06:02 PM, Chris Murphy wrote: > >> https://wiki.archlinux.org/index.php/Uswsusp >> >> It

Swapping to a large sparse file

Can it be done? So far, swapon says: swapon: /var/swapfile: skipping - it appears to have holes. I was hoping that the kernel's swapper would allow the filesystem to allocate real blocks to the sparse file when they are needed rather than check up front to see if they already exist. Maybe the
