That is why everybody will recommend you to use mirrors for blockstorage hypervisors and not RAIDZ.
RAIDZ can be good for files, but is not good for block storage.
Short overview on how this works:
4k secotor size is the default. So you will...
used op's solution, e1000e is successfully blacklisted (first time i was writing wrong command)
still getting (at restart) "Preparing to enter sleep state S5" and dump trace after a timeout of 120 seconds, repeated.
maybe it;s also another thing...
Having spent the last few days fighting all the subtle parts of getting this working, I put together a quick guide on how to get Proxmox, running on a Strix Halo, machine, with working GPU passthrough into LXC containers. To be clear, this is a...
Hi All
Fairly new to Proxmox ;)
Trying to create a BU of a CT and keep getting this response
"ERROR: Backup of VM 101 failed - command 'set -o pipefail && lxc-usernsexec -m u:0:100000:65536 -m g:0:100000:65536 -- tar cpf - --totals...
Thanks for your suggestions. I forgot to add that the failure of the B50 isn't occurring when the VM starts up. I have had the VM completely disabled. My goal was to do passthrough (only one VM needs the GPU), but since vfio wasn't working, I...
Sorry for the necro;
Spent a bit researching this, came to discover that this seems to be a known issue, albeit not very well known, for people who are interested in a (albeit hacky) fix, here is a github repo I found that seeks to resolve this...
I think you have answered your own question, ie it does look like a bug if you can revert a change and get it working again!
However that does assume that no other changes have happened reasonably recently. I use bonding quite a lot, generally...
I had some time to take a closer look at the problem with the missing logs in Task Viewer. Since I access the GUI of my PBS via a Traefik reverse proxy, I searched for the cause of the error in my Traefik config and found out that the problem...
Hi,
That was a beginner mistake.
Real root cause (found 2026-05-06): discard=on was missing from scsi1 in the QEMU config. For over a year, every ext4 TRIM was silently dropped by QEMU and never propagated down to Ceph → 2.7 TiB of orphaned RBD...
Hi, @mickyface
Could it be one more case of the situation solved in this thread?

It depends on your usecase. If you want to have still a working cluster if two nodes get down (due to maintenance or failure) you will need more than three nodes for the reasons Udo explained in his writeup. But if you are fine with just being...
It will be to see the difference of using ceph on lokal storage vs. PVE nodes without local storage and some kind of remote storage.
If any of this will be used in future production environment there will not be much "load" on it. Not CPU nor...
This is a major point. using ceph on this sort of POC will not teach you how to actually use ceph in production since you wont be able to actually put the type of load on it that would be meaningful. Is your intention to use this knowledge to put...
Thanks for your fast answers, looks like i will go this way and only use 2 of the hardware machines and build the ceph cluster virtual. The machines do only have 32GB RAM and an older 6 core CPU, so maybe using 2 hardware machines will be better...
This is what we use for many internal tests, and also in the hands-on labs for our trainings.
Good for functionality and behavior tests as long as performance is not a factor!
Sure! For teaching/learning/debugging this works great.
Example: in my Homelab I have one specific cluster member with 64 GiB Ram and 2 TB local storage for VMs.
I was able to create six virtual PVE nodes with 8 GiB Ram each, construct a...
