[ Blog ] Shutdown #Proxmox #cluster with #Ceph storage
To #shutdown Proxmox cluster and prevent data loss or corruption, especially when Ceph storage is in use, you must follow a specific procedure.
When working with a high-availability infrastructure, performing maintenance tasks can be a delicate process. Shutting down a cluster, even for a planned event like a power outage or hardware http://rviv.ly/GCyTZM
I decided to do a series of posts about my #homelab architecture.
I'm not quite done with the series yet! I still need to detail the roadmap I currently have planned, but it's complete enough at the moment to post.
Enjoy!

[ Blog ] Proxmox upgrade #Ceph #Reef to #Squid
If you are running Ceph Reef in your #Proxmox infrastructure and plan to upgrade to Proxmox 9, you must first upgrade Ceph Reef to Squid to meet the prerequisites.
As a best practice, before proceeding with the upgrade make sure to have a working backup of your VMs and Containers.

[ Blog ] Proxmox #node replacement in #Ceph cluster
If a core Proxmox server fails taking its Ceph OSDs with it, the Proxmox node replacement doesn't have to be a nightmare.
To fix this issue you must cleanly decommission the failed server and correctly perform the Proxmox node replacement to ensure your Ceph data remains resilient.
The Ceph cluster should have the status http://rviv.ly/hDkYPo #replace

[ Blog ] Remove #Ceph #datastore from #Proxmox
To remove Ceph datastore from Proxmox several steps are involved, especially if you want to completely clear Ceph from your system.
Before proceeding, keep in mind that this process will permanently delete all data stored on the Ceph datastore. Make sure to have a working backup of any critical data before proceeding.

PSA: The Ceph Rook update to 1.20 is a bit more involved due to the introduction of the ceph-csi-drivers Helm chart. Have a look at the upgrade docs: https://rook.github.io/docs/rook/v1.20/Upgrade/rook-upgrade/
Also have a look at this GitHub issue for a few things which might be helpful but haven't made their way into the docs yet: https://github.com/rook/rook/issues/17696
