sv-seed-vm-0 will live on this new volume, which will not be redundant. Therefore:

1) sv-seed-vm will be backed up to sv-sms-0-0 according to https://www.wiki.ed.ac.uk/pages/viewpage.action?pageId=568835285 2) at some point in the future this volume should be architected to be redundant as per https://github.com/lsst-uk/somerville-operations/issues/96
