How to hard drive partitioning

[electronik]

Hi!

I have a 465 GB hard drive. When install system select all avalible space. When the system is installed and I create a virtual machine available only 98GB. Where the rest space of my disk?

 

[sg90]

Are you installing from the Proxmox ISO or installing onto a already installed OS?

What does Data Center -> Storage tab show?

 

[electronik]

local
local-vm

 

[sg90]

Your need to select the other storage when creating the VM.

local is the OS /

local-vm is where you will store VM images

I have one hard drive.
How to properly partition the disk to use all the space?

 

[sg90]

Can you past the output of "fdisk -l" on your server (minus the ")

/dev/mapper/pve-root

This is where the OS / Proxmox and other linux software is installed.

The rest of the LVM can be used via local-vm which should be around 369GB.

If you wanted to have more free space you would need to reinstall and adjust the pve-root to be slightly smaller (you could try and do it via a live boot ISO) but I would suggest a reinstall.

However you will not want to go too install as you need available space on the root / for updates & ISO's and other files you will require on the system outside of the VM disks.

 

[electronik]

If I understood correctly, then I need to reinstall the system. And when installing in the field "root" specify 400GB and for system leave 60 GB and 4GB for swap.

 

[sg90]

No set root to 60GB for example. this will then leave an extra 36GB free.

Any new VM's will create a new LVM within the free space left after the LVM root and swap has been created

 

[electronik]

OK.
And how much space set to hard disk? First row?

 

[sg90]

Do you need to store many ISO’s for installation?

You could go smaller but then could find in future you could be hitting the limit of your disk.

I would say 40GB is probably a good size for you unless you need to store lots of ISO’s and other system images.

 

[electronik]

Several virtual machines. For each 100 GB of disk space.

 

[sg90]

40GB would give you nearly 400GB for VM storage.

 

[electronik]

I installed system and again only 58GB free space

 

[sg90]

Are you selecting / viewing the local-vm storage?

 

[electronik]

In DataCenter / loca-lvm (node1) / Summary
392 GB show
Type - LVM Thin

And how to use this space for create VM?

When I create VM avaible only 54 GB

 

[sg90]

When your creating a VM using the wizard.

Once your on the Hard Disk tab, select local-lvm on the storage drop down

 

[electronik]

Only local can select. No local-lvm.

 

[sg90]

Then under Data Center -> Storage you need to select and edit local-lvm and make sure Disk Image/Container is selected under the content drop down.

And enabled is ticked.

If your not sure attach a screenshot of the current settings under Storage
