引导进入新安装的系统后，我在 dmesg 和 /var/lib/syslog 中看到了这个。 grep error /var/log/syslog 的输出：

I 运行 badblocks -v /dev/sda 没有返回错误。
然后我 运行 smartctl --all /dev/sda，也没有返回任何错误。请参阅下面的输出。这包括一个简短的自测

我的问题很简单：你认为可能哪里出了问题？ SSD 应该是 b运行d 新的。出于良心，我很难将日志中的这些错误投入生产。而且这个盒子在其他方面表现正常。
您看到的错误是接口错误，它们不是来自磁盘本身，而是来自与磁盘的连接。它可以是电缆或连接中的任何端口。
由于驱动器上的 CRC 错误没有增加，我只能假设问题出在您使用的机器的接收端。您应该检查电缆并尝试在服务器上使用不同的 SATA 端口。
我刚刚订购了一台配备 1TB 三星 SSD 的新服务器。已安装 Ubuntu 14.04.5 LTS。
引导进入新安装的系统后，我在 dmesg 和 /var/lib/syslog 中看到了这个。 grep error /var/log/syslog 的输出：

我最关心的是这些条目：blk_update_request: I/O error, dev sda, sector xxxxxxxxxxx
I 运行 badblocks -v /dev/sda 没有返回错误。
然后我 运行 smartctl --all /dev/sda，也没有返回任何错误。请参阅下面的输出。这包括一个简短的自测

我的问题很简单：你认为可能哪里出了问题？ SSD 应该是 b运行d 新的。出于良心，我很难将日志中的这些错误投入生产。而且这个盒子在其他方面表现正常。
您看到的错误是接口错误，它们不是来自磁盘本身，而是来自与磁盘的连接。它可以是电缆或连接中的任何端口。
由于驱动器上的 CRC 错误没有增加，我只能假设问题出在您使用的机器的接收端。您应该检查电缆并尝试在服务器上使用不同的 SATA 端口。
