Do I need ephemeral storage?

view full story

http://unix.stackexchange.com – I was running a small instance on Amazon EC2. I'm trying to migrate it to a micro as it requires very minimal processing power. One thing I just learned though, is that micro instances do not come with ephemeral storage like the other instance sizes. Here is the fstab file from the small instance. I just added the nobootwait for the /dev/sda3 line. /dev/sda1 / ext3 defaults 0 0 /dev/sdb /mnt ext3 defaults 0 0 /dev/sda3 swap swap defaults,nobootwait 0 0 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm (HowTos)
