I want to utilise my ephemeral storage as mentioned in this question but I seem to be falling at the first hurdle. I can't even see /mnt:
~$ df -ah Filesystem Size Used Avail Use% Mounted on /dev/xvda1 8.0G 855M 6.8G 12% / proc 0 0 0 - /proc sysfs 0 0 0 - /sys none 0 0 0 - /sys/fs/fuse/connections none 0 0 0 - /sys/kernel/debug none 0 0 0 - /sys/kernel/security udev 288M 8.0K 288M 1% /dev devpts 0 0 0 - /dev/pts tmpfs 119M 152K 118M 1% /run none 5.0M 0 5.0M 0% /run/lock none 296M 0 296M 0% /run/shm
This is from a vanilla instance of an ubuntu AMI (12.04-amd64-server-20120424 ami-a29943cb)
I'm not bothered about resizing the partition, I just want to be able to use the space for writing temp files.
