I can understand that sentiment since you mentioned that this server will only live for another year. On the other hand not doing anything will also have costs: How is the hourly rate of your developers? Let's assume their wage costs are at 50... -
A special device might still help you since you can also configure it with the special_small_blocks parameter that some (but not all) regular data is written to the ssds instead of the hdds. @LnxBil described such a setup here...

I have no experience with special vdev under Proxmox, only TrueNAS. But I think this won't work well, since you are not working with datasets but zvols. SLOG is probably also not helping, because your workload is probably not doing any sync...

You can start with an L2arc device, those are basically disposable and won't fail your pool if they die. You can't mirror them, but you can "stack" them for more cache. Going beyond ~10% of the pool size for cache may be diminishing returns, I...

UdoB replied to the thread CPU usage graph - did something change in July '25?.Well, when did you upgrade to 9.0? You did upgrade, right? Reading https://pve.proxmox.com/wiki/Roadmap I find: "Increase the RRD guest metrics aggregation window to provide greater temporal granularity." ... :)

This is needed to do backups from your ProxmoxVE server to the PBS. For reading from the datastore it's not needed: I setup my local PBS this way and cann pull my backups from my remote PBS, but maybe an even more restricive configuration would...

UdoB replied to the thread Can I install molly-guard on a pve node?.I do install molly-guard on all of my systems, since 15 to 20 years I guess. (Edit: actually I do not know how old that tool is...) This includes all of my PVE and PBS. Nevertheless: ymmv...

As far as i understand it the cache is not that important for the upload of the backup but for verifying backups afterwards. When you start a verify run PBS downloads *all* chunks referenced by the backup you are verifiying from S3 and verifys...

Yes. following screen capture just FYR.

UdoB reacted to alexskysilk's post in the thread How many nodes in a single cluster with Ceph requirement? with
Like.
its an innocent enough question- but there are a lot of gotchas you need to consider. Clusters are made up of 3 elements- compute, storage, and networking. lets touch on each. COMPUTE: - Dell R630 is a 10 year old platform. as such, it offers... -
That probably was a trick question. If by "connected to the second switch using a VLAN tag", you mean that the connecting switch port has a VLAN assigned to it, the the switch removes that egress VLAN tag and on igress, adds the same VLAN. That...

UdoB reacted to Johannes S's post in the thread Docker IPv6 killt IPv6 SLAAC auf dem LXC host with Like.
Warum? Ich finde docker in lxcs zu betreiben extrem frickelig, zum einen muss man für Netzwerkfreigaben mit bind mounts o.ä. arbeiten, zum anderen geht das gerne mal nach Updates kaputt, einige Beispiele: Dezember 2022...

UdoB reacted to alexskysilk's post in the thread Proxmox VE host backup - best option for now with Like.
Backing up PVE in itself is not all that useful or even desirable, and should be downright avoided if a member of a cluster- cluster members are cattle not pets. If you DO want to back up the host (lord knows why) any linux backup method would...
-
Ceph really, really wants homogeneous hardware. Meaning same CPU, memory, networking, storage, storage controller, firmware, etc. While it's true you can run a 3-node cluster, you can only have a 1-node outage. With 5-nodes, can have 2-node...
-
Three nodes will work but need to be aware of it's limitations: With three nodes the cluster can tolerate the loss of one node (due to an fail or system maintenance-reboot etc) but not auto-heal (this would need more nodes). If you can live with...

UdoB reacted to proxmrmomba's post in the thread "Load average" plötzlich auf 3 Server angestiegen // Load average suddenly increase on 3 servers with Like.
Ich habe gestern diese Option auch auf einen Server umgesetzt - und wurde bestärkt von deiner Nachricht. Ja - nach einem Neustart scheint soweit alles okay zu sein. Jetzt bin ich gespannt ob es sich wieder auf schaukelt. Aktuell sehe ich ein...

UdoB reacted to PwrBank's post in the thread Suggestions for low cost HA production setup in small company with Like.
We have a few remote warehouses that needed to have on-prem VMs with redundancy. What we do is have a 3 node cluster of Lenovo Tiny's with 2 switches, 2 battery backups, and offsite backups. Because there isn't a need for instant replication...

UdoB reacted to Johannes S's post in the thread Suggestions for low cost HA production setup in small company with Like.
But such storage hardware also has it's costs. If you need to invest in storage hardware you could also invest in enough hardware to use Ceph, at least if you plan with three compute nodes or more. The story might be different if you happen to...
