Hi everyone,
I installed proxmox (7.1-10) on a 250GB SSD and maybe as a beginner error, I did not extend local or local-lvm to be able to use the whole disk. I would like to use the remaining space (local is 16gb and local-lvm is 30gb) asl well for VMs, containers etc. Two questions:
  1. Which one should I extend? I assume local-lvm?
  2. How do I do that?
Thanks in advance!
 
"local-lvm" can only store VMs/LXCs. "local" can only store ISOs/Backups/Snippets/Templates as well as your root-filesystem of the PVE OS and all other files. So it really depends on what you want and how much of it you want to store on that disk. 16GB just for the PVE OS would be fine but in case you also want to store ISOs, templates and backups there too you might want more space. Its normal LVM/LVM-Thin so you could search for a Debian tutorial that you like which will explain you how to extend your VGs and LVs.

Local-lvm it is then! Thanks a lot, will check on the the tutorial online
 
Here are a few commands to check the current configuration in host shell.
Code: 
pvs
vgs
lvs
lsblk

First make sure your volume group (VG) called pve takes up almost the entire partition.

After that extending local-lvm is quite simple. Just make sure you don't forget to also extend metadata.
Code: 
lvextend -L+100G pve/data
lvresize --poolmetadatasize +1GB pve/data
 
OK, I am a little confused! I am new to proxmox and my assumption is that I need to extend the partition, then the volume group and then the volume, correct?

Here is the output from the commands above mentioned by @jaegerschnitzel:

and the relevant portion of fdisk /dev/sda - p:

Would it now be correct to follow the approach outlined here?
https://help.univention.com/t/how-to-extend-disk-space/10647

Can I also use 'lvresize -l +100%FREE' or do I need to take 'lvresize --poolmetadatasize +1GB pve/data' into account?

Yes thats correct. I assumed that your partition has already the correct size.

You can follow the approach but keep in mind that they delete the LVM partition. If you do that all your data will be lost if you don't have a backup.

You can first extend your metadata and then use
Code: 
lvresize -l +100%FREE pve/data

Thanks!
I do not have any data on /dev/sda3 as of now. Deleting the partition will only delete the data there, correct? Not on the other paritions?
 
Also keep in mind that the PVE installer by default won't use 100% of the VGs capacity for LVs. If your LVs use up all the space then there is no free space if you ever need to store a LVM snapshot.

I have not thought about backup and snapshots so far - so maybe I should do that first :D
 
Hi everyone,
I finally had time to come back to my initial question. I store proxmox backups on my TrueNAS, which is running in a VM on my proxmox server. This also means that I cannot backup the TrueNAS VM on TrueNAS itself.

So I would like to split up the proxmox SSD into

local: 150GB
local-lvm: 100GB

What would be the best way to approach this? I am rather new to Lunix and Proxmox. I guess I „just“ need to extend both partitions and volumes?
 
I'm actually interested in decreasing the size of my local-lvm.. Upon install on my 1 TB nvme drive, the entire disk is taken up... The local-lvm parition ofc being the biggest... I have enough free space remaining taking 200Gigs off of it. I already bit myself trying it first.. I resized the partiitions with cfdisk only to find out that proxmox didn't like that very much.. I've been spending the last 2 hours trying to make things right... All my vm's were inaccecible.

I did run

lvm pvresize but the local-lvm disk didn't have a path anymore so it didn't work..

In the end.. surprisingly enough I deleted the 2 newly smaller partitions I had created off of the free space and resized the lvm disk again to its original size... Proxmox did like that and the disk is working again with my vm's back in play.

But oposite to extending the disk, what would be the proper way to shrink the disk?
 
you should take a look at network chuck proxmox installation video on youtube. he goes through the process of resizing local on your proxmox install after deleting local lvm thin.

Yeh I watched that video a few days ago... He talks about increasing storage from what I believe... Well it's ok.. I'll do a good backup this time and see what happens...

You have to re-create the pool and here is how to do it: https://forum.proxmox.com/threads/reduce-size-of-local-lvm.78676/#post-348810

I had the same problem, worked like charm. Last step takes a while, though.

For completeness, here is how to extend it as well: https://forum.proxmox.com/threads/how-to-extend-lvm-thin-pool.54900/#post-254074

No backup required for extending.

Hi,
sorry for hijacking this topic - but I also need to resize my local-lvm disk size, so I thought it might be better to use an existing topic rather than creating a new one :)

Right now, my "local" storage is using nearly 20% from the available space (60Gb) - and I don't need much more space... So I would like to shrink this to 20 GB and increase the local-lvm storage with the additional 40 GB
I followed some of the steps above...

In addition to that, I do have one VM in particular, that has a Disc Size of 64G assigned (vm 109) - but does not use that amount of space at all.
I would like to shrink that disk... if possible.
I already read that it can cause issues but I would like to give it a try... It wouldn't be hard to reinstall that particular VM - and - restore it's system from a backup...

Hi,
sorry for hijacking this topic - but I also need to resize my local-lvm disk size, so I thought it might be better to use an existing topic rather than creating a new one :)

Right now, my "local" storage is using nearly 20% from the available space (60Gb) - and I don't need much more space... So I would like to shrink this to 20 GB and increase the local-lvm storage with the additional 40 GB
I followed some of the steps above...

In addition to that, I do have one VM in particular, that has a Disc Size of 64G assigned (vm 109) - but does not use that amount of space at all.
I would like to shrink that disk... if possible.
I already read that it can cause issues but I would like to give it a try... It wouldn't be hard to reinstall that particular VM - and - restore it's system from a backup...

I'm on the same boat! Did you have any progress on this? I'm pretty newbie on Proxmox but the basic things are running well for more than a year. I need to do exactly the same thing as you.

Just for anyone else googling it seems to of changed now and this is what I had to do.

Bash: 
#The example is for 10gb then also resizes the filesystem.
# Ran on 7.4-3

lvextend -L+10G /dev/vg0/root
resize2fs /dev/vg0/root

As you can see, there should be ~650GB left.....
but a "lvextend -L+100G pve/data" brings me Insufficient free space: 25600 extents needed, but only 0 available

Anything I missed?
