… /mnt The Azure ephemeral disk (/mnt) gets wiped on VM deallocate, causing Docker images to be lost and pool-resume to fail with WAA timeout. Move Docker data-root to /home/azureuser/docker (OS disk, persistent) and increase OS disk to 128GB to accommodate Docker images. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
