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

Scenario: There is a file system space, need to expand space, the preparation work found that the file system corresponding to the LV VG "free PE" value is 0,VG has no space, so to first expand the VG, and then expand the LV, but the expansion of the VG found "MAX PV" has reached the limit to increase PV, It is necessa

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

Linux LVM learning Summary-delete volume group VG and lvmvg In Linux, how does one delete a volume group (VG? The following describes how to delete a volume group (VG) for reference only. Thank you! In the following example, I want to delete the volume group VolGroup05. Step 1: view the volume group (VG) information,

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

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

Create PV/VG/LV/on linux and create PV first. Create a VG. Then add multiple PVS to the VG. Then create the LV.

information, see LVM structure information. If you want to create a boot disk image, refer to the "root disk image" section. After the hard disk is initialized, you can add the PV to an existing VG: # vgextend vg01/dev/dsk/c0t5d0 # vgdisplay-v vg01 Note that during hard disk initialization (pvcreate/dev/rdsk/c0t5d0), the device used is "rdsk ", when adding a PV to an existing VG, the device used is "dsk ".

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

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
