Known Issues
1. Upgrade Is Stuck in the "Post-draining" State
During the node draining process, the upgrade-repo deployment may get stuck when its Longhorn volume remains in the "Attaching" state. This causes the upgrade flow to stall in the "Post-draining" phase, since the post-drain jobs wait for the upgrade-repo deployment to become ready before proceeding.
The workaround is to delete the Longhorn replica of the upgrade-repo volume on the drained node. This allows the volume to attach and the upgrade flow to continue. Note that any node being drained during the upgrade may encounter this issue, so this workaround may need to be applied whenever it occurs.
