Centos7 – dev sda上的缓冲区I / O错误，逻辑块xxxxxxxxx，asynchronous页写入丢失

我有一个networking服务器，包含HP MSA2040 Storage（10 TB总存储）中的内容。

我不断收到像下面的错误

Jul 31 19:06:24 xxxxxxxx*** kernel: blk_update_request: I/O error, dev sda, sector 7094923416 Jul 31 19:06:24 xxxxxxxx*** kernel: buffer_io_error: 1110 callbacks suppressed Jul 31 19:06:24 xxxxxxxx*** kernel: Buffer I/O error on dev sda, logical block 886865171, lost async page write Jul 31 19:06:24 xxxxxxxx*** kernel: Buffer I/O error on dev sda, logical block 886865172, lost async page write Jul 31 19:06:24 xxxxxxxx*** kernel: Buffer I/O error on dev sda, logical block 886865173, lost async page write Jul 31 19:06:24 xxxxxxxx*** kernel: Buffer I/O error on dev sda, logical block 886865174, lost async page write Jul 31 19:06:24 xxxxxxxx*** kernel: Buffer I/O error on dev sda, logical block 886865175, lost async page write Jul 31 19:06:24 xxxxxxxx*** kernel: Buffer I/O error on dev sda, logical block 886865176, lost async page write Jul 31 19:06:24 xxxxxxxx*** kernel: Buffer I/O error on dev sda, logical block 886865177, lost async page write Jul 31 19:06:24 xxxxxxxx*** kernel: Buffer I/O error on dev sda, logical block 886865178, lost async page write Jul 31 19:06:24 xxxxxxxx*** kernel: Buffer I/O error on dev sda, logical block 886865179, lost async page write Jul 31 19:06:24 xxxxxxxx*** kernel: Buffer I/O error on dev sda, logical block 886865180, lost async page write 

我试图在/ dev / sda上运行xfs_repair这是我的MSA2040存储，这是我得到的报告

我甚至试图运行xfs_repaif -L我可以达到我的数据，但一段时间后卡住了。 我也检查了MSA的界面，一切似乎顺利。

• 我已经更新了CentOS 7，现在nginx不会在系统启动时自动启动
• 在Centos 7上更改Apache 2.4.x的日志文件目录
• 将CentosjoinAD：目录服务无法分配相对标识符
• 在CentOS 7上运行fail2ban，并得到“ssh连接被拒绝”
• 木偶大师的变化并不总是立即被木偶代理人承认

有什么方法可以解决这个问题吗？

提前致谢。

编辑*这也是smartctl报告
