He explained that he can have multiple 1U or 2 old R720XDs. With that he can make an HA setup by spreading the disk between the 2 boxes enable ceph and make a proxmox cluster in a 2 node setup.

You should use ceph rbd with a target of 2 for the rbd pool. Each proxmox node of your setup would be hypervisor AND storage.

I've finally succeed in installing OMSA on proxmox 6.x and in return for all the information i've found thanks to the community, i wanted to share my findings. Here we go. Be sure to be logged as root at all time : sudo su First, be sure to remove omsa from Proxmox 5.4 before upgrading. apt...

If the iDRAC has its own port, you can bond, else you can't. Lokytech (Proxmox on PowerEdge 2950/R610/R730)

+1 for eu.ceph.com edit the pveceph script to change ceph.com to eu.ceph.com if you're installing a new cluster.

Hi, Check on each node : tail -f /var/log/cluster/*.log You should have one node trying to fence another one and your fencing does not work correctly. Correct your cluster.conf and everything should restart correctly.

Re: Proxmox VE - IPv6 Problems A HUGE Thank you, i have successfully configured ipv6 on my Proxmox installation. The missing line : "iface lo inet6 loopback".

Hello everyone, I think Warod is right. I've encountered huge ploblems, is BroadCom BCM 5709 on ESXi as well. It don't support MTU 9000 with iSCSI offload. And it isn't a driver problem, but a firmware one ... We don't have the budget to switch to intel network card so MTU 1500 and VmWare...

Nope, or very complex. How the hypervisor could know what kind of partition the disk has ? (NTFS, ext3, ext4, XFS, MooseFS, ...) It simply can't. But if you use a monitoring server (like Nagios/Centreon, Ichiga, ...) to monitor all your physical and virtual machine, yes. But not on Proxmox...

Nope, you've got it wrong. To have ipmi working, you have to install Dell OMSA. Install it with :

I monitor all other hardware with IPMI through NRPE. You have to do some tuning with sudoers AND/OR "chmod 664 /dev/ipmi0". I joined the scripts for NRPE to check PS,FAN,RAID with IPMI and RAID with MegaCli64. You can also find another plugin to check openmanage with SNMP if you have configured...

I got this issue too. I have joined the dmesg output of my 3 servers. virt1 = Dell PowerEdge 2950 / Uptime:112 days virt2 = Dell PowerEdge 2950 / Uptime:112 days virt3 = Dell PowerVault NF500 / Uptime:43 days All vms : Disks: RAW - VirtIO/IDE on NFS/LOCAL. Network : Debian:VirtIO -...

Like tom said, i think you should go in the Raid card Bios. At the boot of your server, you should see the name of your card and a text with "Press Ctrl + M to enter configuration". Or something like that with whatever is the key combinaison. Press those key and there, define 1 or more Volume...

Openfiler ;)

In my case, i use MegaCli64 from LSI website to monitor a bunch of PE2950 with PERC 6i or 5i. Then i use NAGIOS/NRPE to do the check on my different nodes. That was the start. I added OMSA 5.5 from sara.nl, configure the smuxpeer in snmp and use the nagios plugin : check_openmanage which gives...

Look at the line : Proxmox VE || Open Source virtualization platform for running Virtual Appliances and Virtual Machines || web & cli || active || Bar-metall installer including KVM and OpenVZ management tools ;)

change your network card to the rtl8139. It's 100Mb network card, not a gigabit.

I monitor eth0,eth1 and vmbr0 through Centreon/Nagios with snmp. Snmpd is working with proxmox and openfiler in my case.

HDD R/W speed are mostly linked to your hardware, not the emulation type of the KVM drive. As you can see in the above posts, just the cache=none option change the performance for 3flight. What's your hardware ? SAN iSCSI ? NFS ? Local drive ? In my case, NFS with raw format, the...
