I'm on PVE 9.1.4 and just noticed that /var/log/atop is at 77GB large. This is on a 3-node cluster with 7 LXCs. Logrotation seems to work, keeping 28 days worth of logs: Today is March 1st and the oldest file is from Feb 1st. Gut feeling tell me that's quite a lot, is this a usual value?

Updated from PVE 8-latest to PVE 9.1.1 yesterday, kernel 6.17.2-1-pve. Starting immediately after the upgrade, I get lots of apparmor messages denying dhclient access to a socket: 2025-11-22T09:54:12+01:00 pve2 kernel: audit: type=1400 audit(1763801652.257:138): apparmor="DENIED"...

PVE 8.4.14, cluster of 2 identical nodes + qdevice. Both nodes are single disk with root on ZFS, both boot in UEFI mode. zpool status status: Some supported and requested features are not enabled on the pool. The pool can still be used, but some features are unavailable. action: Enable...

Hi all, I put "best" in quotation marks, because that obviously varies per usecase, but perhaps you can help me gain some insights. My storage is ZFS, cluster nodes are old-ish SFF desktop machines and I don't use any passthrough, in case that's relevant. Guest doesn't use X / Wayland, is i440fx...

I have ZFS replication setup in my cluster, and it replicates 18 LXCs and VMs. 4 are set to "every 15 minutes", the others only replicate once per day or even less frequently. When a replication runs, sshd spams the journald logs (understandably so), see below. I'd never do this in prod, but on...

Is it possible to restore a backup into a new container with a new name? Hitting "Restore" in PvE opens a modal window titled "overwrite restore" - so it's not that. Can't find a suitable commandline either...

Hi all, I've got a 2 machines + qdevice cluster, both machines use root on zfs, PVE 8.7.2 I realized that I could / should(?) `zpool upgrade` but am unsure if I can. According to this guide, I checked if I already use `proxmox-boot-tool`. `proxmox-boot-tool status` on node 1 Re-executing...

Since 2022, I can bind-mount into a running comtainer (see this post). While this still worked in January 2024, it's no longer working now. root@pve:/# pct set 104 -mp1 /media/tmp,mp=/media/usb,replicate=0 400 Parameter verification failed. mp1: unable to hotplug mp1: failed to move 'mp2' into...

Yesterday evening, a grave issue was found in stable kernels. Can someone please confirm which pve-kernels are affected? From Debian micronews: Due to an issue in ext4 with data corruption in kernel 6.1.64-1, we are pausing the 12.3 image release for today while we attend to fixes. Please do...

Hi everyone, since installing the latest updates (see below), my fans speed up every 15 minutes for some seconds. This did not happen before. Using atop, I found <pvesr> and <pvesm> to be the cause, as they briefly bump CPU usage from a 2% average to more than 60%. It's not a big deal for me...

Hallo zusammen, ich habe einen Container auf Knoten A meines Clusters vertüddelt. Ich habe ein Backup vom Freitag und der Container wird alle 15 Minuten repliziert. Ich habe die Replikation sofort gestoppt, so dass sich die Replik auf Knoten B im gewünschten Zustand befindet. Ich würde es...

Hi, messed up a container on node A of my clustered environment. I have a backup from Friday and the container is replicated every 15 mins. I immediately stopped the replication, so the replica on node B is in the desired state. I'd prefer to not lose today's work and use the replica instead of...

Hi, I'm trying to understand how proxmox makes snapshots of VMs and LXCs. If the VM disks and LXC volumes are stored on a ZFS storage - does proxmox then use the ZFS snapshot capability? If not, what's more efficient in terms of disk space - creating a snapshot using ZFS or the proxmox GUI?

Experimenting with 2 nodes (+ QDevice) in my homelab. Old PCs, no enterprise-grade hardware. I have an LXC with a bindmount to a local disk (500GB, no shared storage available) on node1. The disk is not setup as a proxmox data store. Data rarely changes on this disk. Similar local disk available...

I have a small test cluster (without HA). Node 1 runs an lxc, which is replicated to other nodes. In case node 1 goes down, how do I start the container on another node using the replica?

Hi, well, the title says it all: Can I bind-mount a directory into a running lxc?

Hi all, there's a glitch I found that's possibly a bug. I replaced postfix with nullmailer, both provide mail-transport-agent. postfix is in state 'removed' (rc in dpkg terms). No other packages changed / installed / removed. Looking at updates I found this: apt list --upgradable does not...
