Fixed

A fix is available for an issue that caused incomplete file reads and premature end-of-file (EOF) errors when you used the Cloud Storage FUSE CSI driver on ARM64 nodes that use 64 KiB page sizes, such as A4X and A4X Max instances. This issue occurred because the kernel read-ahead mechanism triggered read requests that exceeded the capacity of the Cloud Storage FUSE layer.

To resolve this issue, upgrade your cluster to one of the following versions:

  • 1.33.11-gke.1019000 or later
  • 1.34.6-gke.1154000 or later
  • 1.35.2-gke.1485000 or later

Fixed

In GKE versions earlier than 1.34.6-gke.1154000 and 1.35.2-gke.1691000, mounting Cloud Storage buckets by using the Cloud Storage FUSE CSI driver can experience significant delays. This issue typically manifests as a CreateContainer error that states the following message: failed to reserve container name. This error is self-healing and resolves automatically after the underlying mount operation completes and the container runtime releases the reservation.

The delay is caused by an inefficient bucket access check performed by the CSI driver sidecar by using the ListObjects API method, which can take several hours to complete on buckets that contain millions of empty folders.

The error occurs because the kubelet enforces a strict two-minute timeout for the container creation request. If the FUSE mount process exceeds this time limit while the sidecar is performing the initial bucket access check, then the kubelet cancels the operation and retries. However, the container runtime remains blocked on the first attempt and retains the reservation for the container name.

The new GKE releases fix this issue by replacing the ListObjects check with the GetStorageLayout API method, which performs the same validation but returns almost instantly in most cases.

To resolve this issue, upgrade your cluster to one of the following versions:

  • 1.34.6-gke.1154000 or later
  • 1.35.2-gke.1691000 or later

For GKE version 1.33 clusters running version 1.33.5-gke.2435000 or later, you can mitigate this issue by setting the skipCSIBucketAccessCheck: "true" volume attribute to bypass the check.

There is no supported fix for this issue in cluster versions 1.33.5-gke.2435000 and earlier.

The validation of the HealthCheckPolicy custom resource from the GKE Gateway API is more rigorous in GKE version 1.34 and later. Existing HealthCheckPolicy resources that already contain mismatched type fields in the config are exempted and continue to function. However, updates to any existing policy must not introduce a mismatched type field in the config or change currently mismatched fields to new invalid values.

When the HealthCheckPolicy custom resource is validated, the type field is now verified against the specified health check. For example, if type: TCP is specified but httpHealthCheck is configured, then the fields are mismatched and kubectl rejects the policy. However, for this same example, if type: TCP is specified and tcpHealthCheck is configured, then the fields are valid.

Earlier versions of GKE accept custom resources that don't have matching fields. If you use an earlier version, the type field is used and the configuration in the health check field is ignored.

For more details, see Configure health checks.

In some GKE versions earlier than 1.34.0-gke.2011000, using the Cloud Storage FUSE CSI driver with streaming writes enabled might cause file writes to fail with an Input/Output error on the application side accompanied by 503 errors in the gke-gcsfuse-sidecar logs. This issue occurs when streaming writes are enabled, and is caused by stalls during write operations. Streaming writes are enabled by default in GKE versions 1.33.2-gke.4655000 and later.

To work around this limitation, you can perform one of the following actions:

  • Upgrade your cluster to GKE version 1.34.1-gke.3849001 or later.
  • If you can't upgrade your cluster, disable streaming writes by passing the --enable-streaming-writes=false or write:enable-streaming-writes:false flags when you configure mount options for Cloud Storage FUSE CSI driver. These flags only prevent error reliably when staging writes use fast media types such as SSD or tmpfs. tmpfs is specified using --temp-dir or file-system:temp-dir flags when you configure mount options.
