Proxmox High Availability With Ceph

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

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.

Hi Jim
thank you for this video.We are waiting for your advance SDN video please.
thank you

[ketiljo]

Thanks for another straight to the point video!

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.

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.

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

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.

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

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.

can you show Proxmox High Availability with Home Assistant Containers (LXCs or VMs) and Zigbee Stick?

[rjarmitag]

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?

Now just make a video of migration of virtualbox/vmware workstation/bare machine /esxi to proxmox

You know.. HA, 25 gbit and all sorts of things, although cute and nice to play around with for me personally they are among the least interesting topics ever... I mean talking from a homelab perspective, nice to play around with but absolutely not needed in that seting. Ok firewall HA will be useful but all the ceph/HA... Just my personal $0.01. Would love to see a video on some of the 'promises' you made earlier like install truenas on that NAS you reviewed last time.
