lvmdiskscan | grep LVM 步骤2 创建卷组 VG 1.执行以下命令,创建 VG。 vgcreate [-s <指定PE大小>] <卷组名> <物理卷路径> 本文以创建一个名为 “lvm_demo0” 的卷组为例,则执行: vgcreate lvm_demo0 /dev/vdc /dev/vdd ...
1 existing signature left on the device. 在添加磁盘之前,使用 lsblk 来查看哪些存储空间已经可用或正在使用。 备注:一定要确保将重要数据备份。如果数据已经存在“新磁盘”中,下面的步骤将破坏这些数据。 # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 111.8G 0 disk ├─sda1 8:1 0 ...
Logical Volume (LV): VG’s are divided into LV’s and are mounted as partitions. In this article, we will take you through the steps to configure Disks using LVM in existing Linux machine by creating PV, VG’s and LV’s. Note: If you don’t what to use LVM, you can add disk d...
Disk/dev/sdb: 53.6 GB, 53687091200 bytes 255heads, 63 sectors/track, 6527 cylinders Units= cylinders of 16065 * 512 = 8225280 bytes Disk/dev/sdb doesn't contain a valid partition table fdisk /dev/sdb 将硬盘分为一个分区。结果如下: [root@con4test~]#fdisk -l Disk /dev/sda: 107.3 GB,...

/dev/mapper/data_vg-data /data ext4 errors=remount-ro 0 1 如果用UUID,查看命令是: sudo blkid -c /dev/null 然后更新initframfs: sudo update-initramfs -u 重启之后应该就可以看到自动挂载的逻辑卷了。 由于我是把Ubuntu装到U盘上去了,接下来就是把home目录转移到SSD的逻辑卷上去。原理参考这里。但是这...
Question: I have new unused hard drives, and want to add them to an existing LVM volume to increase its size. How can I add disks to LVM to extend an LVM volume? The biggest advantage of LVM over traditional disk partitions is its support for dynamic partitions; you can create and ...
