proxmox 4

Hi, Proxmox4 (installed on remote server on top of Debian Jessie) was serving well till upgrade in virtual machines started popping out errors making the lxc containers failing to boot. No zfs and ceph and hosting only lxc containers. So I decided to upgrade first to Proxmox5...

Hi, I'm again in a "mon low disk space" on my small proxmox cluster. I saw many threads about this warning but I'm unable to manage the problem. average osd use is 5% only / partition (where /var/lib/ceph is located) is 72% (19GB available) and this seems to be a problem for Ceph # df -h...

Hi, I am aware of this: https://pve.proxmox.com/wiki/Upgrade_from_4.x_to_5.0 - We have three (3) identical nodes: 256Gb of RAM, 4Tb of HD, ... same on each node - Each node is running proxmox 4.4-24 with CEPH enabled - We do not have any shared storage, all VMs are on nodes' hard drives Could...

Hi, I am running a mailserver (ISPConfig) in a proxmox lxc container which was working fine and stopped working recently all of a sudden. All the ports necessary are open in the proxmox host: # iptables -L | grep smtp ACCEPT tcp -- anywhere 192.168.25.110 tcp dpt:smtp...

Is there a way to stop the VM clock from changing it's timezone to the host timezone ? I really had no such issues with Proxmox 4, but it seems for some reason I have this on Proxmox 5. Basically the node has 1 timezone and the VM needs to have it's own timezone inside Windows OS, but it...

Hello, all. I have multiple versions of proxmox running. I'm trying to automate reporting and provide a dashboard that'll show which VMs and containers are running on which nodes. On version 3 there is a very helpful one: "pvectl list". It shows all the data I'm after: VMID, Name, status...

As @guletz stated at https://forum.proxmox.com/threads/crashes-with-zfs-root-and-stuck-on-grub-rescue-prompt.34172/page-2#post-168936, I am also getting only the grub boot prompt in a machine WITHOUT hw RAID with zfsroot running proxmox 4.4 which crashed without a reason. grub > insmod zfs...

Hi there, I've read the documentation and wiki, and can see that a mixed cluster of Proxmox 3, and 4 is not permitted, but I couldn't find anything about proxmox 5. Is it possible to add a proxmox 5 node to a proxmox 4.4 cluster or vice versa? Thank you

Hi, It feels like I read the half of the internet including this forum, but the network config for Proxmox on a Hetzner server still doesn't work... It was so easy with earlier versions and I don't get why it is so hard with the lastest ones. Our aimed setup is actually nothing spectacular...

Hi all. I'd like to share some issues I faced after migration CentOS 6 containers from OpenVZ (Proxmox VE 3.4) to LXC (Proxmox VE 4.1) using https://pve.proxmox.com/wiki/Convert_OpenVZ_to_LXC. I had a CentOS 6 CT installed from a standard template. After migrating it to LXC there were two...

Hi! I'm using Zabbix to monitor my Proxmox containers and I faced the problem. Zabbix item for getting total memory vm.memory.size[total] returns amount of mem on Proxmox host instead of memory inside a container. Although, value MemTotal from /proc/meminfo is correct. Also, Zabbix uses...

I have installed Proxmox 4.4 and i am trying to configure a virtual machine as a communication server that handles all traffic and forwards them to the nodes with private ip. I configured server for NAT networking. My problem is I could ping from proxmox server to vm and from vm to proxmox in...

Hey guys and girls it's been a few day I try to install Proxmox on a ZFS Raid 10 and i can't get it to boot. I read on the forums that Debian and Proxmox can't boot a ZFS root under UEFI so I reverted my server to BIOS but it's the same big mess. My setup is a Dell R710 with a LSI HBA 9211 in...
