    "No IOMMU detected, please activate it." I did AFAIK.

    So tested all the bioses upto 3.1 and still no go - I would like to say that's something was broken in kernel , rather than MB support. Is there anything to try out that would be out of ordinary? EDIT: Got it working with 3.4 bios. Under PCI/PCIe settings there is SR-IOV . This needs to be...

    "No IOMMU detected, please activate it." I did AFAIK.

    Same problem. I know it worked before (and it was 3.1 bios indeed). Now machines are in production and did not needed IOMMU until now. Bios has been updated to 3.4 in the meantime. X10DRi-T4+ MB which is basically same bios. All the same things done as OP. root@blake:~# dmesg | grep -e DMAR -e...

    Proxmox VE 8.1 released!

    If you follow exactly the guide on ceph upgrade it is all good. I made the upgrade. Yes, it's ok to have some nodes running older version. It will report it on ceph status page also, but works. Make the upgrade as guide says and restart the daemons.

    Proxmox VE 8.1 released!

    Same here on my node on little 1L server running nvme+ssd 1TB zfs. Machine is just idle, no machines running.. Something seems to add +1 Load average on top of what already happends. Cpu usage is nonexistent. On my other nodes (44c, 88t cpu) I don't see any difference.

    Proxmox VE 8.1 released!

    Check if apt update and apt dist-upgrade will give you these 3 packages. It seems they were added later on.

    Network drops on new VMs, not old

    For me it was RTL8111/8168/8411 driver issue. I saw quite a few people with same problems and it seems to boil down to power management of network card. If this was turned off , it would keep working normally (at the expense of a little higher power consumption on idle). I moved on from this...

    [SOLVED] Remove node from cluster

    I believe permission denied error came from you not having chorus - You should have at least 3 nodes so that chorus would work. If you have two - as soon as one breaks , the whole cluster will go read-only, because remaining node does not have confirmation if he's "in" or "out". Third node can...

    ZFS on Proxmox and VM

    Putting this as experience - i did see around 2x worse compression ratio if guest system would use xfs and it would be put on zfs storage in proxmox. Just making and LVM storage on proxmox and using zfs in geuest yealded around 2x better compression. This difference comes probably because of...

    Running CEPH? on cheap NVME

    I'm running 10gbe ethernet All nvme's are in either dual or quad carriers that go onto pcie x8 or x16 sockets (running pcie bifurcation). They either have separate forced cooling or full aluminium double sided block heatsink on whole assembly. Temps are also monitored to ensure that there is no...

    Running CEPH? on cheap NVME

    With all respect that was not the question. "works" is wage statement. I'm pretty sure it works on usb flashdrives. I'm asking if someone has one some setup on el' cheapo drives.. 2 drives per node etc. and what the performance on direct IO (no random IO) would sound like.

    Running CEPH? on cheap NVME

    So i'm slowly getting to the point where my small cluster is getting important enough to have redundancy. I'm already running local storage on zfs and samsung entry level nvme's and performance is great.But looking at moving my mechanical backup to something more "solid". So as i know that ceph...

    Opt-in Linux 5.19 Kernel for Proxmox VE 7.x available

    Cool.. i was able to upgrade half of cluster to 5.19 kernel and saw that migration issues between amd and intel dissapeared. But now few days later it seems 5.19 kernel has been scraped as it was replaced with 6.1 kernel. Oh well. Nice timing on my side. Restart all the testing.

    [SOLVED] Remove node from cluster

    I just found that there was still my old node data available on the /etc/pve/nodes path. So just to test it out I just created dummy 1.conf file in the qemu-server subfolder and it immidiately added this node to he list of nodes in web ui. Of course it's with quiestion mark. After removing the...

    [SOLVED] Remove node from cluster

    You probably won't kill the clustet, but you can backup it and remove it and test if something goes wrong. You can always put it back. Just don't do it on working hours. Anyways thanks for the tip on removing the /etc/pve/nodes/<node> folder. I got to same point where it deleted the node but...
