Reduce SSD wear with Proxmox
This one is a work in progress. As my mini PC died with SSD wear, I am becoming more mindful of disk reads/writes. This blog post will be a collection of things that I am doing to get more out of my drives.
Disable the HA services on a single node
Since I’m running a single node, no cluster, no high availability, turns out I can disable these services1.
1systemctl disable --now pve-ha-lrm.service pve-ha-crm.service
pve-ha-lrm is the local resource manager and pve-ha-crm is the cluster resource manager. On a single node with no HA configured they’re doing nothing useful, just generating writes.
Worth remembering that if you ever join this node to a cluster and want HA, you’ll need to turn these back on.
