I have a 5 Gb drive. I've created a pv, then a vg, and then a logical volume size 2GB with sudo lvcreate -L +2GB -n lv-test vg-test.Then I formatted this volume with: sudo mkfs.ext4 /dev/vg-test/lv-test and mounted it with: sudo mkdir -p /mnt/lv-test Now I want to extend this logical volume to 100%FREE (to all size of disk -- 5GB).I am quite new to LVM and I'm uncertain about what is happening here. .

This increases the size of the logical volume lv01 by 300 MiB. Notice the plus sign (+) in front of the size, which means add this value to the existing size; otherwise, the value defines the final size of the LV. The Logical Volume Manager (LVM) provides tools to create virtual block devices from physical devices. LVM is a collection of one or more physical devices called Volume Group (VG), each physical device on the VG called a Physical Volume (PV). A Logical Volume (LV) is a virtual block device that can be used by the system or applications. Step 6) Extend the size of xfs file system. Check the whether free space is available in Volume group (vg_xfs) or not using below command : [root@linuxtechi ~]# vgs vg_xfs VG #PV #LV #SN Attr VSize VFree vg_xfs 1 1 0 wz--n- 10.00g 4.00g [root@linuxtechi ~]# So, we will extend the file system by 3GB using lvextend command with “-r” option

I would to be able to increase the « /boot » (/dev/sda1) by pushing a little bit far my lvm « /dev/sda2 ». I can increase the « /dev/sda », but the free part is going at the end and I’m not able to say to lvm, leave 500Mo before and I’ll give you 500mo after. So by the way I will be able to increase the/boot size.
