  1. Getting a single node Proxmox cluster ready for a second site

    My corosync edit kept reverting because I changed the local copy. Edit /etc/pve/corosync.conf with copy, edit, move and bump config_version. A single node cluster opens no UDP on 5405, so the overlay link can't be tested until node two, and quorum needs a plan first.

  2. How I laid out ZFS pools on a Proxmox host

    I picked mirrors for every pool on my Proxmox host because rebuild time and growing by two disks matter more than RAIDZ1's extra space. Importing an old pool mounted a dataset over /var/lib/vz and hid a running VM's disk. Run zpool import -N and check mountpoints first.

  3. My Proxmox backups covered less than I thought

    My Proxmox backups covered less than I thought: weekly jobs with keep-last=3 only reach back three weeks, the dump folder held another host's files, one host had no job at all, and root mail had gone nowhere for over a year. A real restore drill is next, and I haven't run it yet.

  4. Logging into Proxmox with Authentik

    I added Authentik as an OpenID realm on Proxmox. Proxmox appends the realm to every group name, so the ACL goes on the suffixed name or users log in with no permissions. It also sends the redirect URI without a slash and adds openid itself. I kept the local root login.
