# Restore volume after unexpected detachment
# Recover volume after unexpected detachment
## Overview
1. Now Longhorn can automatically reattach then remount volumes if unexpected detachment happens. e.g., [Kubernetes upgrade](https://github.com/longhorn/longhorn/issues/703), [Docker reboot](https://github.com/longhorn/longhorn/issues/686).
