-A volume provides storage which is not destroyed when a VM is terminated. On Compute Canada clouds, volumes use [https://en.wikipedia.org/wiki/Ceph_(software) Ceph] storage with either a 3-fold replication factor or [https://en.wikipedia.org/wiki/Erasure_code erasure codes] to provide safety against hardware failure. On arbutus the ''Deault'' volume type uses erasure codes to provide data saftey while reducing the extra storage costs of 3-fold replication while the ''OS or Database'' volume type still uses the 3-fold replication factor. The More documentation about OpenStack volumes can be found [https://docs.openstack.org/cinder/latest/cli/cli-manage-volumes.html here]
