飞牛OS扩容Basic硬盘

飞牛OS扩容Basic硬盘

Denvo 树犹如此，人何以堪

前言

我的飞牛OS的某一块硬盘仅512G大小，并将全部容量设置为Basic存储模式，而最近我找了一块1T的新硬盘，希望能替代旧硬盘并扩容硬盘。以下是我的踩坑记录。

下文中设备的路径等请改成自己实际的路径，千万不要照抄！

复制数据

先关闭飞牛OS并取出硬盘，并在Windows系统下使用DiskGenius软件中的“克隆磁盘”功能将旧硬盘的所有数据拷贝到新硬盘中。我使用的是“复制所有扇区”。完成后，我将新硬盘放入飞牛OS所在的机器中，然后打开飞牛OS。

扩容分区

此时打开飞牛OS的设置界面，我们可以看到新硬盘已经成功代替了旧硬盘。不过此时只有新硬盘的前500G在使用，而剩余的500G则处于空闲状态。我们需要把剩余的500G也扩充到前面的存储分区去。

我在测试时，没有卸载掉这个硬盘，最终也成功了，但是个人不建议这么做。

首先，我们通过SSH连接我们的飞牛OS。然后使用sudo fdisk -l看一下此时的分区情况。

根据输出，我这里的实际内容应该是存储在/dev/sdb1里的，但是我们发现后面竟然有Linux RAID的标识。说实话我没有想到，毕竟我之前创建的存储分区使用的是Basic模式，并没有使用任何Raid。然后，输出中竟然还有一个/dev/md0的设备，为什么呢？我们输入sudo mdadm -D /dev/md0，得到如下结果。

竟然使用的是Raid1？好吧，看来大概的情况是飞牛OS把这个单块硬盘整了个Raid1，然后把这个Raid映射到了/dev/mapper/trim_d014f486_5dff_41db_a333_eae448374f08-0中并使用Brtfs文件系统。好了，既然如此，那就有大概的思路了。首先我们需要确保刚才sudo mdadm -D /dev/md0得到的结果中State一项对应的值为clean，然后我们继续操作。

我们首先来对新硬盘中的分区进行扩容。我这个硬盘是GPT格式的，所以这么扩容：

我们使用sudo parted /dev/sdb命令进入目标硬盘的设置，然后输入print all找到我们需要扩容的分区的序号。

我这里对应的序号是1，所以我现在输入resizepart 1 100%，将硬盘内序号为1的分区大小调整至100%。然后输入quit退出。

对于MBR格式的硬盘，请使用sudo fdisk /dev/sdX来扩展分区。最后达到的效果需一样。
