disk partitioning

[kontox]

Hi All,

Is it possible to say in the config to leave a part of the disk unformated or just create a partition but not format or mount it? I have a small PC with a 120GB disk and want to use it as a test machine. The idea is to have 20GB for Talos and 100GB for Ceph. I know it's not best to have Ceph OSD on the same disk as the OS but this is just for a test machine.

There is a disk section in the config but it seems that you have to specify a mountpoint which then wouldn't work with Ceph as far as I know. Any ideas if this can be done?

Hi @kontox.

At the moment the way Talos operates it assumes ownership of the system disk, so it's not possible to do that.

Even though it's not supported, but you could modify partition scheme once Talos is installed (with external system/live CD of some OS). Talos might blow it up on upgrade though.

thanks a lot for the answer, I'll connect an external disk and use that for ceph.

I agree that this would be a very useful feature.

Partitioning would be a great feature.

My hosting provider (Netcup) does not support attaching a second fast ssd. Only slowly cloud storage is possible. I guess it‘s the same by hetzner for instance.

In our case, Talos is no-go only because of this. Our machines have 4x1.9TB disks...
