Below I show some more examples for practical using LVM. I want to write big file to my Ubuntu Virtual Machine and need expand free space from 50GB to 150GB. I have use LVM future for this purpose - this is alternative solution for simple add additional partition and mount it to something mount point.
- Firstly I have only 50GB space.
- Than I have add 100 GB space by simple increase disk space in VmWare.
- In this case after reboot I receive additional unformated partition.
- Than I show my actually LVM name by vgdisplay and done main command - extend my LVM to additional free partition by vgextend
- Than I new size of my LVM (add 100 GB) by command lvextend
- Than I have resized filesystem to all logical volume be resize2fs. This is more examples about fdisk and resize2f - https://geekpeek.net/resize-filesystem-fdisk-resize2fs/.
- And finally I have check in VmWare how many free space have my Ubuntu.
