In Datacenter > Summary we have a Resources tab that give us combined percentages in % of all nodes in CPU, RAM and Storage usage. I want to get these values with pvesh in order to create some nagios checks. Running the following commands I can get the values somehow CPU pvesh get...

I noticed some changes in the output of pvesh utility. I was using it for some nagios scripts and reporting tools that broke with the update. from 5.2 to 5.3 Example of command pvesh get /cluster/resources Was giving back a very detailed json will all nodes, storages vms info etc etc. A very...

Hello, I would like to ask if there is a way to block all multicast traffic coming to specific bridge in a Proxmox node. We can accomplish this at the moment with switch settings and acl. But a node level configuration would be more efficient and "dummy" for all clusters regardless networking...

We are checking live update resources ability in order to give our customers that functionality. We have enabled NUMA on proxmox KMV, and everything seems to be working fine for all operating systems checked ( Centos6, Centos7, Debian 8, Ubuntu 14.04, Ubuntu 14.06 ), except for Debian 7. What...

We are checking firewall options at proxmox ve 4.X in order to give clients control on rules. We create for our clients a PVEVMUser user and give them rights to their kvm. Mainly for Console and Start-Stop. In Datacenter lever we use plenty IPSet lists and Security Groups. In order for...

Hi all, Can we remove this logo somehow in bios boot screen? Where is the picture file located? Thanks

I know that we can change simple ext4 arguments in Proxmox.4 iso installer. Is there any commands for zfs options? I am interested in size and ashift values. Apparently i have the same problem with: https://forum.proxmox.com/threads/zfs-change-ashift-after-pool-creation.25613/ Software raid is...

One proxmox node that hosts only one vm is having high sys% cpu usage. This is translated to high steal% inside vm. 03:41:18 PM CPU %usr %nice %sys %iowait %irq %soft %steal %guest %gnice %idle 03:41:20 PM all 0.24 0.00 5.13 0.01 0.00 0.13 0.00 7.53...

Hi all, My nodes in a Proxmox 4 cluster frequently expirience a kernel bug and remain in a strange state. Most services, including kvms are running well but ssh and pveproxy are unresponsive. I cant even get a iLO console. I am totaly out of control and i have to reset it everytime. I am unable...

Hello, I am having problem with managing ceph services from command line in a Proxmox 4 cluster with ceph hammer. Proxmox gui works but i need cli managment. None of the following works: Old style command sysv /etc/init.d/ceph stop osd.0 stops all ceph services instead of only osd.0 Dec 8...

Hi, I am having a newly installed fully updated from enterprise repo Proxmox 4 cluster. Nodes are HP DL580 gen7 with 4 x E7-4850v1. I am trying to boot a multicore guest with the following kvm options acpi: 0 bootdisk: virtio0 cores: 64 cpu: host hotplug: disk,network,usb ide2...

Hi all, Which option will be safer to run a kvm with many cores? I have a 4 x E7-4850 host with total 80 cores. I have a need to run a 72 cores linux system in this host (I will keep 6 cores for ceph and proxmox) What will be the best cpu conf for the vm? Should i enable NUMA? Should i choose...

I noticed that throttling a vm's disk it also reduces its backup speed. I played with different limits and i confirmed it. Is this behaviour expected? I believe disk throttling shouldn't effect backup speed. Backups happen while kvm running.

I am in the process of upgrading-rebooting my 5 cluster nodes. Unfortunately during upgrading one of them (4th in row), pve-subscription repo errored and it used pve-no-subscription one. I had forgot to comment it. The result is that it has some newer packages and after rebooting this faulty...

I tried to start cman in 2 nodes of a non-Ha proxmox cluster (5 nodes) and i got the following error during start: Starting cluster: Checking if cluster has been disabled at boot... [ OK ] Checking Network Manager... [ OK ] Global setup... [ OK ] Loading kernel modules...

I found that using rate limit at ethernet devices causes bandwidth to be unstable. Here is a iperf example of a vm with no limits. The iperf server has a 1Gbit limit and the result is expected [root@localhost ~]# iperf -c x.x.x.x -t 60 -i 1...

I was in the middle of updating proxmox nodes. I have updated 3 of my 5 nmodes. Today suddenly the cluster started to shutdown all HA kvms. I tried to start them but the HA start procedure couldn't complete. Then i removed them from cluster.conf and i was able to start them. Examining the logs i...

Hi, My proxmox-ceph cluster has 7 nodes and i want to remove a particular node and move ceph osds and mon to an existing one. I have 4 ceph nodes and 3 of them have a monitor. The node i want to remove is configured also as a ceph monitor. The correct procedure as described in ceph docs is that...

Is it possible to bandwidth limit the moving disk from one storage to another? My source storage is sata and everytime i move a disk it causes serious io problems in other vms hosted there.

Hello, I have a working cluster of 7 nodes. I have enabled HA for around 20 kvms. Everything works good until recently i tried to add HA to a kvm and i noticed strange logs. All nodes report pveversion proxmox-ve-2.6.32: 3.2-136 (running kernel: 2.6.32-32-pve) pve-manager: 3.3-1 (running...
