Ted Smith created CLOUDSTACK-1761:
-------------------------------------
Summary: Available local storage disk capacity incorrectly
reported in KVM to manager.
Key: CLOUDSTACK-1761
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1761
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: KVM
Affects Versions: 4.0.0, 4.0.1, 4.1.0, 4.2.0
Environment: Ubuntu 12.04, 4.0.0/4.0.1 agent, 4.0.0 manager.
Reporter: Ted Smith
Priority: Critical
Currently the client is reporting the amount of disk space that has been used
when first connecting to the manager instead of the amount of bytes available.
Output of availableBytes from management-server.log:
"capacityBytes":4956273893376,"availableBytes":318101676032
Output of df from physical host with local storage enabled:
/dev/mapper/somehostname003-root 4840111224 310646138 4285003000 7% /
I'm fairly certain it is related to the two code snippets below. One of them is
passing getUsed and the other is expecting availableBytes.

sscmd.setPoolInfo(pi);
sscmd.setGuid(pi.getUuid());
