Instances Working with Merged Ephemerals
Hi Dina, Alex, I have ngxbio1 working and merging ephemerals on the workers as desired. We were missing a line in cloudinit to install lvm, which is needed to merge disks. Because of the instance type requested, it only has two ephemeral volumes maximum, even though we request four ephemerals. Different types have different limits, so this isn't a code issue at all. I assume this is fine, but if not we'll have to look at the instance types we're requesting for different workloads. I'm going to propagate these changes to ngxbio[2-4] now. Mail to follow. Best, -Stephen
Getting this onto the other instances was easier than expected. This is all done, let me know if there are any issues with it. -Stephen On Tue, Mar 3, 2015 at 6:32 PM, Stephen Rosen <sirosen@uchicago.edu> wrote:

Great! Thanks Stephen. I am submitting the workflows now. Will let you know how it goes. -Dina

Hi Stephen, The jobs are running now and thing look good so far. I can see the combined ephemeral on the spot instances now. Thanks again for your help :) -Dina
