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/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 tmpfs defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 /dev/sdf /apps/ ext3 defaults,acl 1 1 /dev/sdg /data/ ext3 defaults 1 1
Now when I launch this instance as a
micro I get a warning:
Mounting local filesystems: mount: special device /dev/sdb does not exist [FAILED]
It still boots up fine and things seem to be working great, but is there anything I'm missing that I would need the
ephemeral storage for that I'm not seeing or thinking about?
