Check for pool and node errors

When you’re creating and managing Azure Batch pools, some operations happen immediately. Detecting failures for these operations is usually straightforward, because they are returned immediately by the API, CLI, or UI. However, some operations are asynchronous and run in the background, taking several minutes to complete.

Check that you’ve set your applications to implement comprehensive error checking, especially for asynchronous operations. This can help you promptly identify and diagnose issues.

This article describes ways to detect and avoid failures in the background operations that can occur for pools and pool nodes.

Pool errors

Resize timeout or failure

When creating a new pool or resizing an existing pool, you specify the target number of nodes. The create or resize operation completes immediately, but the actual allocation of new nodes or the removal of existing nodes might take several minutes. You can specify the resize timeout in the create or resize API. If Batch can’t obtain the target number of nodes during the resize timeout period, the pool goes into a steady state and reports resize errors.

The ResizeError property for the most recent evaluation lists the errors that occurred.

Common causes for resize errors include:

• Resize timeout is too short
  • Under most circumstances, the default timeout of 15 minutes is long enough for pool nodes to be allocated or removed.
  • If you’re allocating a large number of nodes, we recommend setting the resize timeout to 30 minutes. For example, when you’re resizing to more than 1,000 nodes from an Azure Marketplace image, or to more than 300 nodes from a custom VM image.
• Insufficient core quota
  • A Batch account is limited in the number of cores that it can allocate across all pools. Batch stops allocating nodes once that quota has been reached. You can increase the core quota so that Batch can allocate more nodes.
• Insufficient subnet IPs when a pool is in a virtual network
  • A virtual network subnet must have enough unassigned IP addresses to allocate to every requested pool node. Otherwise, the nodes can’t be created.
• Insufficient resources when a pool is in a virtual network
  • You might create resources such as load-balancers, public IPs, and network security groups in the same subscription as the Batch account. Check that the subscription quotas are sufficient for these resources.
• Large pools with custom VM images
  • Large pools that use custom VM images can take longer to allocate and resize timeouts can occur. See Create a pool with the Azure Compute Gallery for recommendations on limits and configuration.

Automatic scaling failures

You can set Azure Batch to automatically scale the number of nodes in a pool. You define the parameters for the automatic scaling formula for a pool. The Batch service will then use the formula to periodically evaluate the number of nodes in the pool and set a new target number.

The following types of issues can occur when using automatic scaling:

• The automatic scaling evaluation fails.
• The resulting resize operation fails and times out.
• A problem with the automatic scaling formula leads to incorrect node target values. The resize either works or times out.

To get information about the last automatic scaling evaluation, use the autoScaleRun property. This property reports the evaluation time, the values and result, and any performance errors.

The pool resize complete event captures information about all evaluations.

Pool deletion failures

When you delete a pool that contains nodes, first Batch deletes the nodes. This can take several minutes to complete. After that, Batch deletes the pool object itself.

Batch sets the pool state to deleting during the deletion process. The calling application can detect if the pool deletion is taking too long by using the state and stateTransitionTime properties.

If the pool is taking longer than expected, Batch will retry periodically until the pool can be successfully deleted. In some cases, the delay is due to an Azure service outage or other temporary issues. Other factors that can prevent a pool from successfully being deleted may require you to take actions to correct the issue. These factors include the following:

• Resource locks have been placed on Batch-created resources, or on network resources used by Batch.
• Resources that you created have a dependency on a Batch-created resource. For instance, if you create a pool in a virtual network, Batch creates a network security group (NSG), a public IP address, and a load balancer. If you use these resources outside of the pool, the pool can’t be deleted until that dependency is removed.
• The Microsoft.Batch resource provider was unregistered from the subscription that contains your pool.
• «Microsoft Azure Batch» no longer has the Contributor or Owner role to the subscription that contains your pool (for user subscription mode Batch accounts).

Node errors

Even when Batch successfully allocates nodes in a pool, various issues can cause some of the nodes to be unhealthy and unable to run tasks. These nodes still incur charges, so it’s important to detect problems to avoid paying for nodes that can’t be used. In addition to common node errors, knowing the current job state is useful for troubleshooting.

Start task failures

You might want to specify an optional start task for a pool. As with any task, you can use a command line and resource files to download from storage. The start task is run for each node after it’s been started. The waitForSuccess property specifies whether Batch waits until the start task completes successfully before it schedules any tasks to a node.

What if you’ve configured the node to wait for successful start task completion, but the start task fails? In that case, the node will not be usable, but will still incur charges.

You can detect start task failures by using the result and failureInfo properties of the top-level startTaskInfo node property.

A failed start task also causes Batch to set the node state to starttaskfailed if waitForSuccess was set to true.

As with any task, there can be many causes for a start task failure. To troubleshoot, check the stdout, stderr, and any further task-specific log files.

Start tasks must be re-entrant, as it is possible the start task is run multiple times on the same node; the start task is run when a node is reimaged or rebooted. In rare cases, a start task will be run after an event caused a node reboot, where one of the operating system or ephemeral disks was reimaged while the other wasn’t. Since Batch start tasks (like all Batch tasks) run from the ephemeral disk, this is not normally a problem, but in some instances where the start task is installing an application to the operating system disk and keeping other data on the ephemeral disk, this can cause problems because things are out of sync. Protect your application accordingly if you are using both disks.

Application package download failure

You can specify one or more application packages for a pool. Batch downloads the specified package files to each node and uncompresses the files after the node has started, but before tasks are scheduled. It’s common to use a start task command line in conjunction with application packages. For example, to copy files to a different location or to run setup.

The node errors property reports a failure to download and un-compress an application package; the node state is set to unusable.

Container download failure

You can specify one or more container references on a pool. Batch downloads the specified containers to each node. The node errors property reports a failure to download a container and sets the node state to unusable.

Node OS updates

For Windows pools, enableAutomaticUpdates is set to true by default. Allowing automatic updates is recommended, but they can can interrupt task progress, especially if the tasks are long-running. You can set this value to false if you need to ensure that an OS update doesn’t happen unexpectedly.

Node in unusable state

Azure Batch might set the node state to unusable for many reasons. With the node state set to unusable, tasks can’t be scheduled to the node, but it still incurs charges.

Nodes in an unusable state, but without errors means that Batch is unable to communicate with the VM. In this case, Batch always tries to recover the VM. Batch will not automatically attempt to recover VMs that failed to install application packages or containers even though their state is unusable.

If Batch can determine the cause, the node errors property reports it.

Additional examples of causes for unusable nodes include:

• A custom VM image is invalid. For example, an image that’s not properly prepared.
• A VM is moved because of an infrastructure failure or a low-level upgrade. Batch recovers the node.
• A VM image has been deployed on hardware that doesn’t support it. For example, trying to run a CentOS HPC image on a Standard_D1_v2 VM.
• The VMs are in an Azure virtual network, and traffic has been blocked to key ports.
• The VMs are in a virtual network, but outbound traffic to Azure storage is blocked.
• The VMs are in a virtual network with a customer DNS configuration and the DNS server cannot resolve Azure storage.

Node agent log files

The Batch agent process that runs on each pool node can provide log files that might be helpful if you need to contact support about a pool node issue. Log files for a node can be uploaded via the Azure portal, Batch Explorer, or an API. It’s useful to upload and save the log files. Afterward, you can delete the node or pool to save the cost of the running nodes.

Node disk full

The temporary drive for a pool node VM is used by Batch for job files, task files, and shared files, such as the following:

• Application packages files
• Task resource files
• Application-specific files downloaded to one of the Batch folders
• Stdout and stderr files for each task application execution
• Application-specific output files

Some of these files are only written once when pool nodes are created, such as pool application packages or pool start task resource files. Even if only written once when the node is created, if these files are too large they could fill the temporary drive.

Other files are written out for each task that is run on a node, such as stdout and stderr. If a large number of tasks run on the same node and/or the task files are too large, they could fill the temporary drive.

Additionally, after the node starts, a small amount of space is needed on the operating system disk to create users.

The size of the temporary drive depends on the VM size. One consideration when picking a VM size is to ensure the temporary drive has enough space for the planned workload.

• In the Azure portal when adding a pool, the full list of VM sizes can be displayed and there is a ‘Resource Disk Size’ column.
• The articles describing all VM sizes have tables with a ‘Temp Storage’ column; for example Compute Optimized VM sizes

For files written out by each task, a retention time can be specified for each task that determines how long the task files are kept before being automatically cleaned up. The retention time can be reduced to lower the storage requirements.

If the temporary or operating system disk runs out of space (or is very close to running out of space), the node will move to Unusable state and a node error will be reported saying that the disk is full.

If you’re not sure what is taking up space on the node, try remoting to the node and investigating manually where the space has gone. You can also make use of the Batch List Files API to examine files in Batch managed folders (for example, task outputs). Note that this API only lists files in the Batch managed directories. If your tasks created files elsewhere, you won’t see them.

Make sure that any data you need has been retrieved from the node or uploaded to a durable store, then delete data as needed to free up space.

You can delete old completed jobs or old completed tasks whose task data is still on the nodes. Look in the RecentTasks collection on the node, or at the files on the node. Deleting a job will delete all the tasks in the job; deleting the tasks in the job will trigger data in the task directories on the node to be deleted, thus freeing up space. Once you’ve freed up enough space, reboot the node and it should move out of «Unusable» state and into «Idle» again.

To recover an unusable node in VirtualMachineConfiguration pools, you can remove a node from the pool using the remove nodes API. Then, you can grow the pool again to replace the bad node with a fresh one. For CloudServiceConfiguration pools, you can re-image the node via the Batch re-image API. This will clean the entire disk. Re-image is not currently supported for VirtualMachineConfiguration pools.
