Hi, We use for some years proxmox on cluster of dell m610 blade servers with no trouble. We plan to order dell R720 to create a small cluster of 3 nodes to store some vm out of our SAN architecture. Anyone can confirm it's utilization/performance with proxmox 3 ? * For local storage we plan to...

hi all, We use here proxmox 2.2 on 9 clusterized nodes. After one week of production all seems ok but for two days now we have a problem with the gui. Logged on the gui, 8 nodes are shown down (appears in red) and the linked vms too. Only two nodes are shown up... But logged via ssh on each...

Making live migration on our new proxmox cluster provide a lot of packet loss. If we ping the vm from an outside host we lost ten packets during migration. If we ping an external machine from the vm we can see the ping stop send packets during migration. But after migration, ping send packets...

Hi all, We attempt to install last proxmox version on our dell M610 on which run proxmox 1.9 During install process we get an "hard disk not found" error. It seems there is no more driver in the proxmox distrib/kernel. The following hardware on our server ...

Hi all, I prepare our migration from 1.9 to 2.1 proxmox cluster. We use 6 host connected to Hitachi SAN. We have a "guest" Volume Group on which we create LV for each KVM Virtual Machine. We have 70 KVM VMs running in production and we want to reduce the downtime due to the migration. In...

Hi, We have Oracle Application Server on our KVM proxmox vm. This VM is connected to a bridge on the proxmox host (interface bonding + vlan tagging). Our vm should receive multicast packets in order to work with a central database server. All worked fine with proxmox 1.8 but since migration to...

Hi, We use here a 7 node proxmox cluster. We use only kvm virtual machine on dell m610 servers. We started this cluster two years ago and all worked perfectly. Since two weeks, nodes freeze randomly. The only solution was to reset the server.... Reading the forum i saw that was frequently due to...

Hi, We use proxmox 1.8 We use lvm storage on shared .SAN We have made a mistake adding disk to vm. After we add the disk in the vm we tag this disk with LVM from the vm without partitionning the fresh disk. Now in the host when we do pvscan or lvscan we can see the "guest lvm" disks. The master...

Hi all, After upgrade from 1.7 to 1.8 i have a node which wnat no sync to cluster. I have removed the node from the cluster and add it again but i have always the same result : On the master node pveca -l : CID----IPADDRESS----ROLE-STATE--------UPTIME---LOAD----MEM---DISK 1 : 10.16.2.1 M...

Hi, Reading the doc i found migration guide to upgrade from 1.7 to 1.8 proxmox version for one proxmox server. I understand we must reboot the vm after the migration node. My question is about cluster migration sequence. Can i have my master node in 1.7 version and my slaves noces in 1.8. The...

Hi all, i have a question about proxmox and lvm. In our vm we have a first disk partitioned like this : /boot => vda1 / => vda2 => On this we create LVM groups for root and for swap On this vm we add a second disk (vdb) => point to /dev/vg_guest/vm-213-disk-2 From the vm we create a new...

Hi, we have 2 nodes runing proxmox 1.7. we use shared storage between proxmox servers on FC SAN using multipath. This shared storage is used as LVM storage named vg_guests on proxmox. On this storage we create Virtual raw disk as LV for each virtual machine. We attempt to migrate our Xen vm...

Hi all, i attempt to create new vms in proxmox using command line. Reading man and some posts on the forum but i encounter a problem with vm disk storage. I use an LVM storage in proxmox, the name of this storage is "guests" in the web interface. I launch the following command : qm create 104...

Hi all, We attempt to make a script to easily deploy centos5 vm (lvm based storage) on proxmox as there is no "template" for kvm in proxmox. We create the LV on our proxmox storage and we "make" the virtual disk using fdisk/LVM. Next we copying the filesystem from our centos5 golden image to...

Hi, We have setup a 500 Go LUN on our SAN. We map a LVM Volume Group "vg_guests" on this LUN. We want more space to store more VM. From proxmox vision what is the best practice : Add a new LUN to the existing "vg_guests" to exetend the VG size Add a new VolumeGroup "vg_guests2" Thanks for your...

Hi all, i attempt to understand what append in a proxmox cluster if the master node fail. what is the impact for the slave node ? all will be broken or just the administration task frozen ? We plan to migrate from our 10 Xen node (running on centos 5.5) to proxmox and we would understand if...
