LVM | Logical Volume Management | Combining Drives Together

Let's go over LVM. Logical Volume Management is a staple on the fedora distro and an option on many other Linux distros. So today, I will be adding another physical hard drive to an existing volume and showcasing the power of LVM!

next time you forget sudo just hit: 'sudo !!' after, it will execute previous cmd with sudo, )

Really great video, Chris. I had largely avoided lvm, because I hadn't seen it all laid out in one place and wasn't exactly sure I knew what I would be doing. This makes the process accessible. Thanks much!

No need to run resize2fs. You can just give -r parameter to lvextend which will do the filesystem resizing automatically. Anyway, nice video :)

I came across this video after hours of searching. This has saved me a lot more hours. Excellent. Thank You!!

Thanks Chris for teaching me how to extend the LVM. I knew how to setup LVM's but never knew how to extend them with more drives. Another good thing about LVM are creating snapshots using Timeshift. If you have LVM configured using BTRFS it is super powerfull with creating snapshots.

First 5 minutes are all I needed to understand in a simple way the whole point of LVM. Thanks

Thank you very much for this, I've come back to this multiple times in the last years. It has made my life so much more easier. Also thanks for your other vids, they are really a great help.

I was just wondering all about LVM over the last few days! Thanks for reading my mind.

Regarding the drawbacks you mentioned about LVM, one way to deal with them is to have a RAID layer below LVM. That way you used the logical drives from the RAID configuration instead of using "real" drives as PVs. Its very hard to lose data that way.

Hi Chris. An addition ere: LVM doesn't necessarily have to use partitions. It can be built on any set of any block devices: partitions, raw drives, RAID devices, files, memory, etc. Things can go really crazy with it.

And I was avoiding LVM as I couldn't figure out how it works :D
Now waiting for BTRFS video

I watched. Wow, I wish you would have been the Instructor that I had during one of the early Linux classes. How you explain it and simplify it out, is what more Instructors need to do. Also, the split screen -- with the commands in the background -- is incredibly helpful; also, as you work in the Terminal windows, is what I wish would have been presented when I was in courses for this. It would have helped drive it home. Most of our stuff was just walk through some tutorial steps, and it really didn't deepen the knowledge. It was rote learning, instead of "real learning" like this. Now, I feel more comfortable with disk organization. [Also, I plan on becoming a Patreon too for you.]

Great video Chris, used LVM about 10 years ago when I first found Linux. Also loving the System 47 LCARS screensaver in the background rather than both doing Cmatrix.

This vid is way above my GNU/Linux grade, but I still enjoyed it. Thanks for sharing Chris Titus Tech.

Passing -r to the lvextend command will automatically resize the FS for the extended LV. So, in this case it would be "lvextend -l +100%FREE -r /dev/vg1/lv1" so then you don't need the final resize2fs call. Great video, thanks!

[ratchetrussell]

I love your channel your tutorials have helped me immensely. I'm currently working as a support tech fresh out of college just switched over to fully over to linux for work (using Ubuntu) haven't looked back XD

[andthesunsets]

This is by far the best explanation of LVM. thx!

[odpisani]

LVM rules....but I don't use it so often I always need to re-learn from the scratch :D Thank you for the great video. It is very helpful.

[pseudorealidad]

10/10 best explaination i've seen of this. Thank you!

A few days I bought a Samsung SSD of 1TB for games specifically and other files as well. Thanks for making this video and keep up the good work Uncle Chris.
