Understanding task creation statuses

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

Task creation status Meaning


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 hostname.


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


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


There is another task running and it's using the same agent. DataSync runs the tasks in the queue in series (first in, first out). For more information, see Queueing task executions.
