Dear starcluster community,

I created an ec2 cluster using m3.xlarge instance (2*40GB SSD). I did not see any scratch space or /scratch folder at all. Here is the disk space layout.

root_at_node001:~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvda1 20G 5.6G 14G 30% /
udev 7.4G 8.0K 7.4G 1% /dev
tmpfs 3.0G 176K 3.0G 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 7.4G 0 7.4G 0% /run/shm
/dev/xvdaa 37G 177M 35G 1% /mnt
master:/home 20G 5.6G 14G 30% /home
master:/opt/sge6 20G 5.6G 14G 30% /opt/sge6

In my application, I need a scatch folder on each node that has about 50G space. Is there a way to do that? I don't really need /home or /opt/sge6 stuff. And I don't run mpi applications.

Maybe I should recreate an AMI?

Thanks!
