How do I create VMs on the local-lvm / lvm-thin storage?

[sontek]

I just did my first proxmox install ever on a 500gb disk. I used all defaults so it is using ext4. After install I wanted to create my first VM and when I clicked create VM it said there is only 90gb available on the "local" disk for creating VMs:



So I went digging into the interface to find the other 400gb and it seems like proxmox is using LVM to manage the disk and it created another storage called "local-lvm" that has 338gb free but it doesn't show up in that storage dropdown.

Under disks there is a "LVM-Thin" disk that reflects the same 338gb with the name "data"

So how do I get proxmox to let me create VM images on that larger disk where most of the storage is allocated? Why is there 2 separate storages created by default?

Check the storages under `Datacenter -> Storage`. There should be the local-lvm storage. Make sure that the `Content` field is set to `Disk Image` and `Container`.

This is what it looks like:



Its setup for Disk Image, Container, and is enabled.

OH! I completely misunderstood what I was selecting here. As you can see from my first screenshot I was still selecting the media to boot it (ISO), which is the only one setup for ISO Image storage.

But once I moved passed that I was able to use the local-lvm storage to put the VM on top of.

Thanks!

I got caught by this as well.
For the sake of interface clarity where IMHO Proxmox has margin of improvements I would suggest one or more of the following:

- On the OS tab rename the "Storage" to "Source Storage"
- On the OS tab above Storage add a header called "Installation media"
- Move the OS tab after the disk one

Just some ideas
Thanks

Hi,

- On the OS tab above Storage add a header called "Installation media"

I sent a couple of patches for discussion, which implement these suggestions (well, I used ISO storage ). I think the Installation media one is pretty good.

- Move the OS tab after the disk one

Unfortunately, we can't do this, because settings like the default drive controller are auto-selected depending on the OS type. And it would break the workflow for people that are already used to it

Just some ideas
Thanks
