logic block, but compared to the basic physical storage media (such as partitions, disks, etc.), it contains LVM the relevant management parameters. c. Create a volume group ( Volume Group)LVM volume groups are similar to physical hard disks in non-LVM systems, which consist of physical volumes. You can create one or more LVM partitions (logical volumes) on a volume group, and an LVM volume group consists of one or more physical volumes.d. Create a logical volume ( Logical Volume ) LVM logical

1. LUN partitioning LUN is just a logical thing. Within the storage device, the relationship between the LUN and the physical hard disk is like the relationship between the logical volume and the physical hard disk in the host, that is, the relationship between the LV and PV, in different categories. It can be understood that LUN is the logic driver on the Logical Disk after RAID. But the difference is that LUN is a physical hard disk on the host. The

Recently, I found that there are more or less many problems in the online articles on creating a library with bare devices bound to linux lv, which is easy to mislead beginners. Therefore, I sorted out the preliminary steps for directly creating a library on a bare disk. OS: RedHat 4.4First, add a hard disk to the vmvm and enter the system to create a partition. We use sdc1 to divide the lv[Root @ Oracle ~]

built by the Fedora community to deliver high-quality software packages for RHEL and derivative distributions such as CentOS, scientific Linux, and more. After the Epel is loaded, it is equivalent to adding a third-party source. Note is the source. If the software does not meet your requirements, then make it yourself, in fact, their production is not difficult, later I will how to make their own software.

In this case, there is only one group "vg_ezsetupsystem40a8f02fadd0" that is created under DEV/SDB2.Next, check the logical volumes that exist in the volume group and use the Lvdisplay command:$ sudo lvdisplay Use Lvdisplay to display information about the available volumes (such as device name, volume name, volume size, and so on). $ sudo lvdisplay/dev/vg_ezsetupsystem40a8f02fadd0 ---Logical volume--- LV Path/
