As a prerequisite to upgrade to proxmox from 6.0 to 7.0 (prerequisite to upgrade the proxmox nodes to bullseye), the 3 ceph servers need to be upgraded to the octopus
Migration guide: https://pve.proxmox.com/wiki/Ceph_Nautilus_to_Octopus
The 3 nodes to upgrade:
| Status | Assigned | Task | ||
|---|---|---|---|---|
| Migrated | gitlab-migration | T3579 Meta-task: upgrade infrastructure to Debian Bullseye | ||
| Migrated | gitlab-migration | T3771 Upgrade proxmox hypervisor from version 6 to version 7 + debian11 migration | ||
| Migrated | gitlab-migration | T3787 upgrade ceph nodes from nautilus to octopus |
We (all sysadm \o/) followed the guide one step at a time.
