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

             Summary: Incorrect File System Size Reported with Amazon Elastic 
File System (EFS)
                 Key: AMQ-6441
                 URL: https://issues.apache.org/jira/browse/AMQ-6441
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.11.1
            Reporter: Ismail Bhana


I'm setting up Active MQ in production with a shared file system master/slave 
configuration (KahaDB). I've set everything up and mounted the EFS on both EC2 
instances. 

When I check the disk free stats I get 8 exabytes for the shared file system: 

$ df -h 
eu-west-1a.***.efs.eu-west-1.amazonaws.com:/  8.0E     0  8.0E   0% /mnt/efs 
Unfortunately, ActiveMQ cannot interpret this number: 

Store limit is 102400 mb (current store usage is 0 mb). The data directory: 
/mnt/efs/kahadb only has -8796093022208 mb of usable space - resetting to 
maximum available disk space: -8796093022207 mb 
Store limit is -8796093022207 mb, whilst the max journal file size for the 
store is: 32 mb, the store will not accept any data when used.
