In this video I deploy Ceph onto my MS-01 Proxmox cluster.

The fun project to cover would be how to shut down a proxmox cluster with Ceph as it does not seem to have an out of the box solution.
Now just make a video of migration of virtualbox/vmware workstation/bare machine /esxi to proxmox
can you show Proxmox High Availability with Home Assistant Containers (LXCs or VMs) and Zigbee Stick?
A few issues to think about when you do migration (live or offline):
1. Try to use the same hardware CPU generation and brand on the nodes. Live migration from Ryzen to older AMD CPUs does not work flawlessly, the destination vm will spike at 100 % CPU and be unresponsive. You will have to restart the vm, so no live migration in this use case. Maybe it has been fixed in Proxmox 8, I used Proxmox 7.
2. Live migration between different processor brands is not possible, so no live migration between AMD and Intel CPUs.
3. Migration (live or offline) of vms with USB-attached devices is not possible. That ruined my idea of having a Home Assistant vm with failover, sigh.
Great content as usual. Just some notes on the ceph cluster itself. You want to set global flags like NOOUT,NOSCRUB and NO-DEEPSCRUB when rebooting ceph nodes as they will start to rebalance when the first node is down if you dont.
everytime i go to build out a project you put out a similar video going over it. If you somehow put out a video on how to use the zfs over iscsi storage option in proxmox I'll be floored
The live migration should have happend without a ping being dropped. The disconnect you saw was only the serial console cutting over to the different hv. If you woulf have done it over ssh, you should have seen no dropped ping or at max one, depending on the speed of your switch.
Just a thought. A nicer test of the ha might be to run your ping command from another node rather than the one you migrated. That way you can see if the service really is fully available to external clients
Why do you go to the effort of cloning and then moving the disks? You can choose the storage at the time you do the clone. Does that not work with Ceph?
Great video!
Just as a head's up — instead of initiating the migration via the command line, you can just click on the migrate button in the GUI.
a small hickup and voilà
Thanks for another straight to the point video!
