Symptoms
Cloud Infrastructure Log in PCP contains notifications about resource pcs-storage shortage in a particular OACI Network Group. But reported size of a cloud storage is incorrect.
Example (values in GB):
The resource pcs-storage is nearly used up on NG _NG_NAME_. Only 18% is left. (69863 out of 84274 are used)
But corresponding cloud storage size is 45.8TB and usage is 31.5TB (14,3TB free, it is about 30%) .
Cause
This is a result of the algorithm that OACI uses to calculate reported values:
Usage (69863 GB) = Sum of all disk sizes of VM's/containers located on the corresponding cloud storage
Real usage in Virtuozzo is smaller because virtual disks are dynamic (disk file becomes bigger when disk usage grows inside VM/container).
Cloud Storage Size (84274 Gb) = Usage + remaining space on the cloud stotrage that is retrieved from Virtuozzo
Since reported values do not reflect real storage size/usage this behavior has been registered as software bug CCU-17581
Resolution
Contact your Technical Account Manager or pta@odin.com to clarify status of bug CCU-17581
Provider can check real remaining space directly in Virtuozzo or in PCP:
PCP > Cloud Infrastructure > Virtualization Nodes > SERVER_NAME > Cloud > Virtuozzo storage Capacity
