Longhorn

v1.11.3Storage & Data
Jul 1, 2026

Longhorn v1.11.3 is a bugfix rollup addressing over a dozen stability issues across volume operations, backups, and instance management. One upgrade prerequisite applies: the CSI external provisioner is now v6.3.0, requiring Kubernetes v1.34 or later when upgrading from v1.10.x or v1.11.0.

  • breakingKubernetes v1.34+ required when upgrading from v1.10.x or v1.11.0

    The bundled CSI external provisioner is bumped to v6.3.0, which requires Kubernetes v1.34 or later. If your cluster runs an older Kubernetes version and you are upgrading from Longhorn v1.10.x or v1.11.0, bring Kubernetes to v1.34+ first before applying this upgrade.

Key changes (7)

  • CSI external provisioner bumped to v6.3.0: clusters must run Kubernetes v1.34+ before upgrading from v1.10.x or v1.11.0
  • Fixed iscsid restarts leaving V1 volumes inoperable, blocking PVC resize and other volume operations
  • Fixed nil pointer dereference panic in longhorn-instance-manager during replica rebuild
  • Fixed deadlock causing recurring trim jobs to fail, and separate fixes for volume expansion getting stuck
  • Fixed migration engine being deleted while target node was still transitioning to ready
  • Fixed backup uploads to S3 failing on NetApp appliances, and fixed System Backup RecurringJob incorrectly pruning the newest CR
  • Fixed longhorn-manager panic in BackupController during backup deletion, plus HTTP response body leaks in support bundle and webhook polling; reduced webhook TLS Secret contention at scale
