Understanding Task Creation Statuses

Following, you can find information about the possible statuses (phases) a task might go through when it is created.

Task Creation Statuses Meaning

CREATING

AWS DataSync attempts to mount the Network File System (NFS) or Server Message Block (SMB) location. The task transitions to the AVAILABLE status without waiting for the AWS location to mount. Instead, AWS DataSync mounts an AWS location before every task execution and then unmounts it after every task execution.

If the task remains in the CREATING status for more than a few minutes, your agent might be having trouble mounting the NFS or SMB file system. Check the task's ErrorCode and ErrorDetail values. Mount issues are often caused by either a misconfigured firewall or a mistyped NFS or SMB server host name.

RUNNING

The task is being executed.
AVAILABLE The task is configured properly and is available to be started.

UNAVAILABLE

If an agent that is associated with a location goes offline, the task transitions to the UNAVAILABLE status.

QUEUED

There is another task running and it is using the same agent. DataSync runs the task in the queue in series. For more information, see Queueing Task Executions.
