I'm running on AWS m2.2xlarge instances using the ~800 gig ephemeral/attached disk for my data directory. My data size per node is nearing 400 gig.
Sometimes during maintenance operations (repairs mostly I think) I run out of disk space as my understanding is that some of these operations require double the space of one's data.
Since I can't change the size of attached storage for my instance type my question is can I somehow get these maintenance operations to use other volumes?
Failing that, what are my options? Thanks.
