I had a VM using RAW storage format on a ZFS storage object. I needed to delete the RAW hard drive files but couldn’t find them and the “remove” button was greyed out. One post mentioned using “qm rescan” which then allowed the poster to use the remove button but that didn’t work for me. After some research I found out that virtual drives on ZFS storage aren’t actually files but are “ZVOL”s. After a bit more research I came across the solution below to remove these drives manually.

I have a limited number of IPv4 addresses available to me on my servers. So I am really frugal with how I assign them.

Whenever possible, my preference is to use NAT off of the main Proxmox IP. However I struggled to get this setup while also using the built-in Proxmox firewall that comes in version 4.0. Having an enabled firewall is an absolute requirement for me.

In this article I have documented the final working solution. (more…)

One of the things I like having is a remote system I can access and work on from anywhere. In the past this has meant using either a dedicated server (expensive) or VPS (which is just a VM… too slow).

With Proxmox, I figured I had the option of using a container, which would mean very good performance and not having to dedicate a whole server. However none of the container templates that I could find came with a desktop or VNC out of the box. After much tinkering with different options, I think I finally have found the best solution for getting a running headless VNC server in a Linux container. (more…)

If you load Proxmox 4.0 from OVH or any of their affiliates you end up with a partition scheme that gives you one big logical volume for data that is formatted to EXT3.

That will work but it isn’t desirable. Starting with Proxmox 3.4, support for the ZFS filesystem was added. ZFS is more than just a file system though and as a result it adds in enhanced functionality. In this article I will be walking through how to transition from the OVH, KimSufi, SoYouStart default partition layout on an existing system running Proxmox to a layout with ZFS. (more…)

On Thursday I released an article detailing how to get Proxmox setup and also how to configure networking with IPv6. However that article got long and I just said I would address the firewall in the future. Well, that’s today because I need to get the configuration stuff written down before I forget. In addition to the firewall there are some other security house keeping items for a new proxmox install, that includes disabling the root account and using sudo and changing the default SSH port. So let’s go.

The base OS under Proxmox is Debian. Debian is great and it is lighter-weight than Ubuntu so I am all for using it.

If you are already somewhat comfortable with Proxmox and Debian configuration and just prefer I get to the point then (more…)
