-------------------------------------

             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.

       try {

            KVMStoragePool localStoragePool = _storagePoolMgr
                    .createStoragePool(_localStorageUUID, "localhost", -1,
                            _localStoragePath, "", StoragePoolType.Filesystem);
            com.cloud.agent.api.StoragePoolInfo pi = new com.cloud.agent.api.StoragePoolInfo(
                    localStoragePool.getUuid(), cmd.getPrivateIpAddress(),
                    _localStoragePath, _localStoragePath,
                    StoragePoolType.Filesystem, localStoragePool.getCapacity(),
                    localStoragePool.getUsed());

            sscmd = new StartupStorageCommand();
            sscmd.setPoolInfo(pi);
            sscmd.setGuid(pi.getUuid());
            sscmd.setDataCenter(_dcId);
            sscmd.setResourceType(Storage.StorageResourceType.STORAGE_POOL);
        }
