If you’re trying to resize a logical volume and encounter an error like ‘Insufficient free space’, it means that there’s not enough free space in your volume group to expand the volume. You can check the available space using the ‘vgdisplay’ command, as described above. If you’re ...
In this case, I added a-(dash) before the2Tsize, indicating I want that quantity of space subtracted from the existingsales-lvcapacity. The difference between the two commands is small but important. You now have the returned capacity to the VG for use in another LV. You can use the ex...
The volume group size is almost 60GB, and it is unused, so we can create LVs in it. Let us divide the volume group into equal sizes to create 3 Logical Volumes. That means 60GB/3 = 20GB. Each Logical Volume will be 20GB in size after creation. Method 1: Creating Logical Volumes u...
As I mentioned in starting of this tutorial logical volumes are flexible in nature. It means we can resize them easily. Following command is used to add additional space in LV. #lvresize –L +[Space which we want to add] –r /dev/[VG where LV is created]/[LV Name] Let’s fill-up...
Re-size the file-system back, In this step if there is any error that means we have messed-up our file-system. # resize2fs /dev/vg_tecmint_extra/tecmint_reduce_test Resize File System Mount the file-system back to same point.
Creating volume snapshots as a means of data backup and redundancy Encrypting two or more physical partitions with a single password Resizing file systems as needed on a desktop PC Utilizing RAID functionality, particularly RAID levels 1, 5 or 6 LVM Functionality Apart from its primary uses, the...
This also means that if a host downgrades to the old LVM version, it would lose access to any VGs it had created with a system ID. To avoid this, the system ID should be removed from local VGs before downgrading LVM to a version without the system ID feature. ...
These options are useful if you are replicating configuration files around a cluster. Use ofhosttags = 1means every machine can have static and identical local configuration files yet use different settings and activate different logical volumes by default.

Logical Volume Management, orLVM, is a storage device management technology that gives users the power to pool and abstract the physical layout of component storage devices for flexible administration. Using thedevice mapperLinux kernel framework, the current iteration, LVM2, can be used to ga...
LVM是Logical VolumeManager(逻辑卷管理)的简写,它是Linux环境下对磁盘分区进行管理的一种机制,它由Heinz Mauelshagen在Linux 2.4内核上实现。LVM将一个或多个硬盘的分区在逻辑上进行组合,做为一个大的硬盘空间来使用,当硬盘的剩余空间不够的时候,可以将其它的硬盘加入到分区当中,这样可以实现磁盘空间的动态管理。
