系统里识别nvme为 nvme0n1 iostat识别盘为 nvme0c0n1
[硬盘类] 系统里识别nvme为 nvme0n1 iostat识别盘为 nvme0c0n1
上线时遇到三星pm1733的盘 或 pm1725b等盘的时候有概率出现盘符名字不对的问题
具体表现为：系统里识别nvme为 nvme0n1、iostat识别盘为 nvme0c0n1
修复方法：
1、
<button title="Copy Code" class="copy" style="touch-action: manipulation; border: 1px solid var(--vp-code-copy-code-border-color); padding: 0px; background-image: var(--vp-icon-copy); direction: ltr; position: absolute; top: 12px; right: 12px; z-index: 3; border-radius: 4px; width: 40px; height: 40px; opacity: 0; background-position: 50% center; background-size: 20px; background-repeat: no-repeat; transition: border-color 0.25s ease 0s, background-color 0.25s ease 0s, opacity 0.25s ease 0s;"></button>
sed -i 's/ixgbe.allow_unsupported_sfp=1/ixgbe.allow_unsupported_sfp=1 nvme_core.multipath=N/g' /etc/default/grub
grep nvme /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg
如是UEFI模式装的系统，则使用如下命令更新
grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg重启机器
2、有些设备在执行完上一步之后nvme盘会变得无法识别,再次删除刚刚添加的内容
<button title="Copy Code" class="copy" style="touch-action: manipulation; border: 1px solid var(--vp-code-copy-code-border-color); padding: 0px; background-image: var(--vp-icon-copy); direction: ltr; position: absolute; top: 12px; right: 12px; z-index: 3; border-radius: 4px; width: 40px; height: 40px; opacity: 0; background-position: 50% center; background-size: 20px; background-repeat: no-repeat; transition: border-color 0.25s ease 0s, background-color 0.25s ease 0s, opacity 0.25s ease 0s;"></button>
sed -i 's/nvme_core.multipath=N//g' /etc/default/grub
grep nvme /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg
如是UEFI模式装的系统，则使用如下命令更新
grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg重启机器
