rebuild/reconfigure PHX storage to improve performance ------------------------------------------------------ Key: OVIRT-649 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-649 Project: oVirt - virtualization made easy Issue Type: Task Components: General Reporter: Evgheni Dereveanchin Assignee: Evgheni Dereveanchin Currently the storage setup is not well suited for CI workloads: 1) production and builder VMs are on the same RAID volume, so there is no resource tiering 2) all the storage is DRBD backed, even for data that doesn't need to be sync'ed 3) RAID50 is used which is slow on random writes 4) there is no dedicated DRBD sync network This ticket is to track changes to optimize the storage and make it perform better while not losing reliability.
