7. Cloudstack 2.2.4

Cloudstack 2.2.4 was released on 16 May 2011

Important

The behavior of storage allocation is more conservative in 2.2.4 than in 2.1.7 and prior releases or 2.2.0-2.2.3. Cloudstack will no longer create volumes on primary storage resources that have a storage percentage used higher than that defined by global configuration. Previously Cloudstack would allocate a primary storage resource up to 100% full. This space reservation is required as a fix to cases where snapshots of VMs could not be taken when the storage had been allocated to 100% full. The use of a threshold setting allows the administrator to reserve space for snapshots in progress for existing volumes. Deployments with primary storage that is close to full should examine the value of this parameter before upgrading. If all primary storage resources are more full than no new volumes can be created after upgrade.
