What
We are several versions behind on Proxmox on Coherence, as of writing the current version of Proxmox is 7.1-7 while we are still running 5.4-13(!). This means that we can't make any new LXC containers with newer distributions because they are simply not supported by Proxmox 5. Several attempts to upgrade Coherence have been made in the past, but I hope this time we can actually do it! It would also be nice if we could use this as an opportunity to clear old unused VMs and containers off Coherence.
Upgrading Proxmox path
A upgrade from 5 to 6 is needed, and from there on we can upgrade from 6 to 7. - [1] - [2]
Upgrade stuff (can be done already when backups are possible)
Please make backups first before you upgrade a VM or container
There should be a backup system available on backup-nfs before we start.
Debian containers should be Debian 10 at least before we can upgrade Proxmox, and Ubuntu 18.04 it seems.
Thinking steps required
* Backups - if we mess up, how do we bring things back?
- Need at least 4Tb to do this.
- Redundancy - Can we upgrade some other host and migrate? Would this be a good plan going forwards?
- Probably not required - Proxmox upgrade scripts should check containers before upgrades.
- Upgrades - All VkMs/Containers below need to be ticked off
Backup
A system called `notnotapp` has been setup and has 4x 1TB in raid 5 storage, meaning we have 3TB available for backup with redundancy. Although, roughly 1.8TB has been used for the mp3 share and the user data. Which should leave enough for VMs however, it is advised to remove your backup once the VM has been successfully upgraded to leave enough room.
