I really would like to give ZFs a try on proxmox. Reading several topics / forums about ZFS there is one thing I have noticed a couple of times. They advice to NEVER put your main OS on a ZFS volume. If I choose ZFS during normal ISO-install, will proxmox/os be put on ZFS? And are there ways...

There might be 3 things (or a combination of these 3) 1) check SSL ========== First check if ssl-certificates are ok, from a good node check: grep pve-ssl /var/log/syslog If certificates are ok, what you can do on all nodes (at least I can) at the same time is: 2) restarting services...

on one node we use 960 Gb intel S3520 series. So for software raid-10 and hotspare it's a total of 5 disks per server. We don't use ZFS (yet) becuase we started historical with software raid and use puppet kind of installs. Did not find the time to migrate to another kind of storage. In stead of...

We run proxmox on Supermicro systems, using local storage, Intel SSD-disks in software RAID-10 + spare. I am aware of the fact that software-raid is not adviced, but we just love software raid :) We have done several tests and we have some problems with the so called "time to first byte" on...

Did you find a solution for this issue?

same issue here, the last node added is not visible in the webinterface. pvecm status and corosync.conf are ok and the same on all nodes.

What we did on every node to fix it was: for s in pveproxy spiceproxy pvestatd pve-cluster; do /etc/init.d/$d stop; done Check if any corosync processes are running and kill them ps uxaw | grep corosync killall -9 corosync Then restart the cluster /etc/init.d/pve-cluster start If...

It looks like the nodes are not responsive at all anymore. On 1 node I do a service pveproxy restart, but it hangs. If I check the status now, this is the output: service pveproxy status ● pveproxy.service - PVE API Proxy Server Loaded: loaded (/lib/systemd/system/pveproxy.service; enabled)...

a pveproxy seems to take a long time and produces an error: [822264.538357] INFO: task pveproxy:15176 blocked for more than 120 seconds. [822264.538399] Tainted: G O 4.4.49-1-pve #1 [822264.538429] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message...

We have had some issues with the cluster. Right now the cluster seems to be up and running again and all VM's are online. With pvecm status, I see all nodes are ok. === pvecm status Quorum information ------------------ Date: Fri May 12 20:35:01 2017 Quorum provider...

I checked the manual at seagate: http://www.seagate.com/files/www-content/support-content/enterprise-storage/solid-state-drives/master/Nytro%20XF1230%20SATA%20SSD%20Product%20Manual.pdf The following attributes might be very useful to monitor: 231 SSD Life Left (%) ==> Indicates the...

First of all I'd like to say: proxmox rocks :) We are using Seagate XF1230-1A0960 SSD-disks. Using the proxmox GUI I see that the wearout indicator status is N/A (see attached image). However when I check the SMART-status I see attribute 177 (Wear Leveling Count) and these have the following...

When removing a KVM VM using the GUI I noticed that the /var/lib/vz/images/vm-id does not get removed. So when removing VM with id 101, the directory /var/lib/vz/images/101 still exists although the contents of the directory is empty. It might not be a problem, I'm only describing what I see :-)...

We use KVM with virtio network and for each VM we like to know how much traffic a VM generates on i.e. a monthly basis. So actually we would like to receive a monthly report: 2014-10 ===== VM100 : 239 Gb VM101: 17 GB etc. Can this be done and/or implemented on proxmox-level (would be a great...

That sounds quite impressive. We have managed to install using software RAID as well. Performance is OK for us although I didn't compare it using hardware raid and BBU. Did you follow the 'install proxmox on software raid how to' or did you create your own way of installing proxmox on a...

Thanks for the feedback Shukko. As you did install proxmox in different ways one further question for you. We would like to use the 4 node Supermicro Chassis with an integrated LSI 2208 SAS-controller , see: http://www.supermicro.nl/products/system/2u/2027/sys-2027tr-h72rf.cfm. This chassis does...

I know that the "proxmox advice" is to use a good hardware raid controller with a BBU. We prefer however a software raid-1 configuration. The latest Intel SSD disks (i.e. DC S3500 Series) comes with data protection in case of a power loss so a BBU is not really necessary anymore. Can anyone...

Dear proxmox, I like to test the cluster-configuration on a proxmox server. The guidelines listed at http://pve.proxmox.com/wiki/Proxmox_VE_Cluster are based on a 1.x installation (at least the screenshots). Is setting up a 2.x cluster done in the same way? In other words, can I use the manual...

Suppose we have 10 VM's within the proxmox environment and each VM is a 80GB image. When using the backup-option within proxmox set on a daily basis, will it copy 800 GB each day to a backupserver (if data within a VM is modified) or will it use some kind of blocklevel backup? Gijsbert

From what the GUI says, the VM is running: Status: running Hostname: vu-testje3.blah.com Uptime: 5 days 01:44:04 IP Address: 192.168.1.14 CPU Utilization: 0 100 0.00% Memory/Swap (MB): 1 3072 1MB Disk space (GB): 0.13 8.00 1.62% The VNC is connecting to 192.168.1.11 (main IP of server)...
