How do I find and mount instance storage on my EBS backed EC2 instance?

  • 772

I'm running an m1.xlarge EC2 instance. According to EC2 specs, it should come with 4 x 420GB instance stores. When I SSH into my new machine, I don't see any of these drives. All I see are my EBS volumes:

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/xvda1      7.9G  1.6G  6.3G  21% /
devtmpfs        7.4G   52K  7.4G   1% /dev
tmpfs           7.4G     0  7.4G   0% /dev/shm
/dev/xvdf       197G   97G   91G  52% /data
/dev/xvdg        25G  3.2G   21G  14% /journal
/dev/xvdh       9.9G  151M  9.2G   2% /log

This is a Mongo server and I'd like to use instance storage as temporary space while backing up Mongo. How do I locate the 420GB instance stores and mount them? I've read the EC2 docs and I am still unclear.

    In the launch wizard, you need to explicitly add the instance store volumes and specify device nodes for them:
