基于springboot+vue的摄影作品社区（项目源码）基于springboot+vue的摄影作品社区（项目源码）系统采用前后端分离的 B/S 架构。后端基于 Spring Boot 2.7.2 与 Java 1.8 构建，以 MyBatis-Plus 完成数据访问、PageHelper 实现分页，用 MySQL 8 存储业务数据；身份认证采用 Sa-Token 轻量级框架并整合 JWT 令牌，配合 Redis 实现图形验证码缓存与会话存储；前端使用 Vue 3 与 Naive UI 构建界面，由 Vite 完成构建，看板统计图表基于 ECharts 渲染。系统面向普通用户与管理员两类角色：用户端提供注册登录、作品上传与归档、多条件检索浏览、作品集管理、分类与标签管理、摄影圈专题、回收站、个人设置与公告查看等功能；管理端提供数据看板、用户管理与公告管理等功能。立即下载

500G的ATA硬盘，通过PCIe挂载到p2020子卡，系统是vxworks 6.9。
下面是两个日志，每个日志都很奇怪。

可以确定上面的分区操作是没有成功的，为什么这样呢？
需要说明的是，这块硬盘之前分过区，但是没有成功，然后在电脑上删除错误的分区后重新分区，又把所有的分区删除，然后重新挂载子卡上分区，就变成上面的错误了。
