ansible-playbook bootstrap.yml 命令中的 tidb-ansible 错误

Question

我正在尝试通过 TiDB ansible 安装 TiDB。我指的是https://pingcap.com/docs/v1.0/op-guide/ansible-deployment/ 中的文档，在此过程中，我遇到了命令 ansible-playbook bootstrap.yml 的以下错误。虽然磁盘未满，但我收到磁盘已满错误。请让我知道修复错误的步骤。谢谢！

这是使用df -h. | tail -n1命令来确定inventory.ini中所有机器的ansible_user对应的主目录分区的空间使用情况。发生错误时，分区使用率可能为 100%。如果确认还有空间，请重试。
