Setup scripts that mount the extra ebs volume to /data don’t run on the host.create spawn hosts so /data on those is on / partition. This has lead to consistent failures of RHEL70 OM packaging sanity tests on mms, on-prem-mms-4.0, on-prem-4.2, and on-prem-4.4 since August 19th. This appears to be related to mongodb toolchain upgrades, which reduced the space available on / from 14GB to 5GB. This shouldn't have impacted mms as it uses ebs volume mounted on /data, but it seems that it isn't being mounted on spawn hosts.
These failures block us from releasing Ops Manager (next week), and makes it difficult to test multiple patches over the last few days.
