Can we dynamically allocate storage in proxmox ?

[wasim.devops]

Hello Team,

I have total 1TB of storage with for my proxmox setup.

1) I have allocated 100 gb each to 8 servers : so total used is 800Gb i.e with 8 running VM.

2) Now I want to configure 400gb more for one new server. So is there a chance that I can allocate 400gb to new VM ?

3) Can we dynamically allocate storage in proxmox ? Please suggest.

4) In this case can we over commit storage in proxmox? Please suggest.

This is called Thin-Provisioning. What is your current Storage-Config? LVM? LVM-Thin? ZFS?

Its LVM Thin.

3) Can we dynamically allocate storage in proxmox ?
4) In this case can we over commit storage in proxmox?

Please suggest.

Yes you can assign more space then you really have, but you can not write data on the Disks over it's maximum size.
So keep in mind if you have 1000MB Disk and Thin-Provision 1200MB, you still can not write more than 1000MB!

Yes you can do that. That what that "Thin" in "LVM-Thin" means. You can thin provision your storage.
