Hi. I upgraded my PVE 4.4-20 system (pve-manager/4.4-20/2650b7b5 (running kernel: 4.4.95-1-pve) to the last PVE 5.1 (pve-manager/5.1-41/0b958203 (running kernel: 4.13.13-2-pve). The upgrade ended without any error but after the reboot the networking on the server is really slow! I can connect...

Hi. I have a PVE cluster made with Proxmox VE 5.1 nodes. Sometimes when start tasks on VMs (start, stop, etc) I get this error on the nodes console: unregistered_netdevice: waiting for lo to become free. Usage count = 1 When I get this error the task seems to be hanged and does not complete...

Hi. On my Proxmox 5.1 system I sometimes find some KVM virtual machines hanged. Last week this happened on two different machines: one Windows 2016 and one FreeBSD 10.3 (pfSense 2.3.4-p1): the Windows 2016 virtual machine was hanged with the CTRL+ALT+CANC screen on the console completely...

Hi. I have a Proxmox 5.1 with a root ZFS RAID1 pool and one Windows Server 2008 R2 virtual machine. When the VM was running I added a new VIRTIO hard drive on the local-zfs storage and I received an error. So I stopped the VM and tried to restart it. After this I am not able to start any virtual...

Hi, when I was using hardware RAID controllers on old servers I was using the RAID controller commands (megacli for LSI, arcconf for Adaptec and so on) to monitor array and drives status. What I should use for ZFS? Are smartctl, zfs-zed and zpool status enough to be alerted and to predict...

Hi. I have some nodes with a local LVM Thin pool. On one node the metadata pool is full and I cannot start any new containers: root@node3:~# lvs -a -o+metadata_percent LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert Meta% data...

I mean, with qcow2 and raw files (and old OpenVZ private root) it was very simple to migrate virtual machines to another node (using the "migrate" function in the GUI or simply moving files through SSH). How it works with ZFS or LVM-Thin storage?

Thanks. But will I be able to easily move virtual machines from node to node? Please forgive me for all these questions, but I was accustomed to snapshots on OpenVZ containers on LVM local storage and now that I don't have them on LXC containers I am trying to find the best solution I can, not...

Hi, I have a shared storage based on a NetApp system which exports through NFS or iSCSI. I am not able to make snapshot backups for LXC containers on NFS storage, so I am looking for something better. I read on https://pve.proxmox.com/wiki/Storage that even iSCSI does not support snapshot, but...

Hi Dietmar, I read the page at https://pve.proxmox.com/wiki/ZFS_on_Linux and https://forum.proxmox.com/threads/zfs-vs-hardware-raid.30243/, so I am about to convince myself to not use hardware RAID on the new nodes and install Proxmox directly on ZFS RAID1. But what about existent nodes? Should...

Thanks. But I already have an hardware RAID configured on all nodes, and using ZFS on hardware RAID is not advised (https://en.wikipedia.org/wiki/ZFS#ZFS_and_hardware_RAID). Or do you advise me to create a striped ZFS pool on the LVM logical volume /dev/mapper/pve-data (which is now an ext4...

Thanks! I was wrong when I told you that I am using the LVM storage. I am using a dir storage on a LVM logical volume. Is there a way to have snapshots backups on it without converting all containers to LVM? I wish to maintain the directory storage to let me easily migrate containers through the...

Hi. After upgrading to Proxmox VE 4 snapshots are not longer possible for LXC containers and they need to be suspended during the dump even if I am using a LVM storage with free space for snapshots in the volume group. I know that the snapshot works with a ZFS storage, but I wish to understand...

You are right, sorry. I opened a new thread for this problem.

Hi. I have a Proxmox 3.4 installation running on kernel 2.6.32-43-pve, and I'm following the guide at https://openvz.org/Docker_inside_CT to run Docker inside an OpenVZ container. The problem is that when I try to enable netfilter support to the container it does not work...

Thanks. Actually I have the pve-kernel-2.6.32-43-pve version running on my PVE host, but I cannot execute the command to enable netfilter on the container: root@node1:/# vzctl set 151 --netfilter full --save vzctl: unrecognized option '--netfilter' Could you help me to find out where I am wrong?

Hi, how I can install pve-kernel-2.6.32 (2.6.32-150)? The last 2.6.32 version I have on my PVE 3.4 installation is pve-kernel-2.6.32-48-pve. Could you help me please?

I realized that these two nodes have an high load average even if apparently they haven't heavy processes running: root@node5:/var/lib# w 18:50:21 up 2 days, 23:26, 2 users, load average: 8.41, 7.89, 6.41 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT root pts/0...

Hi. I have a PVE cluster with 7 nodes with the same configuration (same network and same switch), but I have some random problems on two of them (node5 and node6): sometimes they loose the communication with the cluster, they are very slow, I cannot enter in containers ("vzctl enter CTID" does...

Hi. When I try to backup an OpenVZ virtual machine I get these errors: Sep 21 15:09:09 INFO: Starting Backup of VM 306 (openvz) Sep 21 15:09:09 INFO: CTID 306 exist mounted running Sep 21 15:09:09 INFO: status = running Sep 21 15:09:09 INFO: mode failure - unable to detect lvm volume group Sep...
