[SOLVED] How do I swap drive for a larger drive and expand LVM partition

[Zoker]

Hi there,

Since my 500GB nvme storage was to small over time, I upgraded to a 1TB Samsung 980 drive.
I used the dd tool to make an exact copy of the drive and just replaced the old with the new drive.

Now I have the issue, that since I just copied the old drive (including partition) to the new drive, the new space is not yet used.
Currently my partitions look like this:

How can I expand the LVM partition to use the currently unlocated space?
I tried to google, but was unsure which guide is the correct one (expand LVM or just expand partition etc.).

So if someone could give me a hint, that would be amazing!

Thanks!

A quick google search for "lvm extend physical volume disk resize" brings up https://www.thegeekdiary.com/centos...-in-lvm-by-extending-the-disk-partition-used/
Whether this article is an exact match to your needs is unclear as there is not enough details in your post. Make sure you understand the commands you are running - heed to the warning in the article "Potential Data Loss Warning"

@rason I believe you misunderstood the poster - there is no new _additional_ disk involved.

Sorry, for that, you're right. I've deleted my post. OP should follow the tutorial you've provided

@bbgeek17 Thanks that link helped a lot. At first it seemed scarry to delete a partition, but everything worked out great!

Hi, i am in this situation, i have cloned with dd my 500hdd into 1tb ssd and of course i have 500gb of unformatted space according to the command sfdisk --list-free /dev/sda, also parted > free shows me the exact starting and ending sector. how can i extend my local-lvm partition? This guide makes you delete and create a new one, but i have VMs in it

Hi MrnMrk,
this is no problem, all vm's are working.
Follow the YouTube instructions.
But keep your old 500GB HDD (this is your current backup) .

# set the type to Linux LVM 30

Not sure if this has changed with Debian 12 (PVE 8.0), but this partition type is 43 (Linux LVM) currently. Rest of the commands still work perfectly

NCom you are the real MVP. Followed your instructions exactly, only thing I had to change was the type which for me was 43 instead of 30. Worked like a charm.

Tip for others who are nervous about upgrading in place or increasing storage like this - get one of these cheap SATA drive duplicators and back up your entire OS drive before you start! I felt much more confident going in knowing I could fall back to my old drive if something went wrong.
