The four Proxmox nodes have one (SAMSUNG MZ7LH480HAHQ 480G) SSD each with disk wear at 79, 63, 73, 72%. They are mostly consumed by (local storage) kube VMs.

  • Do we have any cold spares ready?

  • How does the replacement work? Wait for 99% wearout? Offline dd? Half-online zfs mirror?

  • Kube local VMs seem to not be able to migrate to other nodes.

  • Kindly stop requiring local storage for kube applications :)

Now at 81 65 75 74 (+2% on each). Napking math projection says about a year until there really needs to be orders for replacements.
