我想挂载/ dev / sda2。 我该怎么做？
贝娄是fdisk，df，lvmdiskscan，lvdisplay，vgdisplay，lvscan的输出。

扩大评论：
目前，您只有10GB的1TB分区。
为了扩展你的根卷，你有两种可能性：
之后，增加了卷组的大小，可以扩展逻辑卷和文件系统的大小。
你想要做什么基本上是你的select，但请记住，你不能在磁盘上创build无限数量的分区。
我不会描述这些程序，因为我不是这方面的专家，这两种可能性已经被比我更适合的人详细描述了。 这个教程很容易在互联网上find。
1）创build新的物理分区/ dev / sda3（并在其上设置lvm标志）。 做这个parted
mkpart primary 0% 100% set 3 lvm on q
2）扩展现有卷组以包含新的/ dev / sda3分区
VG_NAME=`vgdisplay | grep "VG Name" | awk '{print $3}'` vgextend $VG_NAME /dev/sda3
3）创build逻辑卷（用GigaBytesreplacex的大小）
LV_NAME=/dev/vg_centos6264bit/lv_data lvcreate -L xG -n $LV_NAME $VG_NAME
4）在逻辑卷上创build文件系统
mkfs.ext4 $LV_NAME
5）挂载逻辑卷
mkdir /data mount $LV_NAME /data
