Summary about how to manage PV, PE, VG, and LV in LVM with disk flexibility

convert the actual partition into the 8e system format, and the command pvcreate is used to convert the partition into the physical volume that can be used. PE (physical extend) entity extended Block PE is the smallest storage unit of LVM, generally 4 MB. It is the basic unit of VG. PE is the unit of data storage for VG, for example, block. The PE size is not fixed, but changeable. Therefore, PE determines

Migrate VG in SUSE Linux to Redhat System

1. in the SUSE system, a new storage disk is larger than the size of 5.4T to be migrated, because converting XFS to EXT3 will occupy more storage space than the original one. I am suspended for about 6 TB, the attached storage method depends on the storage brand and type. Let me talk about EMC CX700, that is, first record the WWN of the HBA card, connect the HBA to the storage switch, configure the ZONE, connect its server to the storage, and install EMC's POWERPATH on the server, use the powerp

PrefaceAPP Scenario Description:When you are unable to plan your storage properly, the storage re-planning (eg, one or several apps that write bigdata for a certain LV-mount point in a post-maintenance job may soon be out of space for your LV mount point, but it's worth noting that Does your other LV mount point have a large storage space? Basically not applied to this LV mount point to write data?) According to the previous description, we know that the problem solution we might be able to choo

PV, VG, LV, PE, and Le Relationship Diagram

Several Concepts in LVM: PV (physical volume): physical volume is at the bottom of the logical volume management system and can be partitioned on the entire physical hard disk or the actual physical hard disk. VG (volume group): A volume is created on a physical volume. A volume group must contain at least one physical volume. After a volume group is created, it can be dynamically added to the volume group, A logical volume Management System project

This article was sponsored by Xiuyi linfeng and first launched in the dark world. The previous article introduces the basic LVM knowledge. This article describes how to expand the logical Volume LV and volume group VG of LVM. We know that the logical volume of LVM is equivalent to a partition. Since it is a partition, it has a distinction between the size and space. What should I do if the current logical volume space is insufficient? Don't worr

LVM implementation principle (PV, VG, LV, PE, le)

The LVM is attached to the DM function. The DM (device Mapper) is a ing Framework mechanism provided by the Linux 2.6 kernel from a logical device to a physical device. Under this mechanism, users can easily develop storage resource management policies based on their own needs. Currently, logical volume manager in Linux is popular, such as lvm2 (Linux Volume Manager 2 version) and evms (Enterprise Volume Management System) and dmraid (device mapper raid tool) are all implemented based on this me
