    [SOLVED] After Upgrade ZFS pool gone

    Hi Wolfgang, yes, on the machine exist two ZFS pools: the proxmox "rpool" on 2 2,5" HDDs and the pool "tank" (where the vms are stored) on 2 x 3,5" HDDs. As I said, at the moment, after downgrade of ZFS packages, the pool tank is there again. When I will find a time window again, I will try...

    Error kvm : cpu0 unhandled wrmsr & unhandled rdmsr

    Hi, yes, I am having this issue too. Especially when there is (heavy) load on the (virtual) network interface, e.g. while doing backup using NFS from the proxmox host to a vm (openmediavault). This leads often to a server hang up, because NFS connection seems to go to nirvana and hosts ist...

    [SOLVED] Safe cluster shutdown procedure?

    Re: Safe cluster shutdown procedure? If I got it right, you want to move one cluster node to another rack? Then the easiest way would be to live migrate the VMs to the two nodes that you can leave online, shutdown the node you want to move, move it to the new place, start it up again and...

    'ipcc_send_rec failed' on a non-cluster installation

    Ok, solved it. I found out that /etc/pve is created from the SQLite database /var/lib/pve-cluster/config.db. There was an old lock file, which I deleted, cleaned /etc/pve, rebooted the machine and the whole thing is fine again. Thx. How can I mark this thread as solved?

    KVM - Mac OSX as Guest

    Sorry, but I can not give you any help by virtualizing Mac OS on KVM. At the time I asked here in this thread I did not get it working and gave up. At the moment I do not have any need to virtualize Mac OS on KVM. Der Nasenmann

    KVM - Mac OSX as Guest

    It seems as there is an issue with the ftp server. I am also not able to access it. Perhaps you have to wait a bit until the ftp is accessible again.

    How to spin down disk when idle

    Hi, my Proxmox VE home server has one 2,5" system hdd containing the virtual machines and three 3" 3,5 hdds as RAID5 containing data which is accessible over Samba shares and NFS. If there is no access to the shares, the data hdds spin down (configured with hdparm). This works flawlessly...

    Bonding of interfaces

    Hi, if you configure LACP on your switch, you should use 802.3ad as bonding mode. If you want to use balance-xor on Proxmox, then I think you should configure your bonded ports on your switch as trunks, but no LACP mode. Best regards, Der Nasenmann

    Versions of PVE packages differs on two cluster nodes

    Hi, thanks for your replies. aptitude full-upgrade shoul be comparble to apt-get dist-upgrade? No, both of them did not solve the problem. Also, I added another debian repository to my sources.list, but the Proxmox packages should only be found in the Proxmox repositories, so I do not...

    Oops, it seems that now there is another issue. The two nodes have different levels of package versions, although the sources.list of the the nodes are the same. How can this be? Node1: asterix:/# pveversion -v pve-manager: 1.6-2 (pve-manager/1.6/5087) running kernel: 2.6.32-3-pve...
