If your pve host is plugged on the trunk port, it should reveive all packets with all VLAN tags. You do not have to do any special configuration to get acces to the Proxmox host. Try to ping a machine on one of the LAN your switch is connected to.

since PVE uses the latest ubuntu LTS kernel ( currently from Ubuntu 16.04 + patches) so usually you need to check if the hardware is supported by ubuntu acoording to http://h17007.www1.hpe.com/us/en/enterprise/servers/supportmatrix/exceptions/ubuntu_exceptions.aspx#.WbqeUa202-Y your...

could it be that your switch is reacting strangely to the fact it now sees multiple MACs adresses on the same port ?

check if you're logged to your iscsi portal iscsiadm -m session -P1 for each LUN you should see iSCSI Connection State: LOGGED IN iSCSI Session State: LOGGED_IN

no LVM and LVM-thin have different properties but you cannot say one is *faster* if you're interested about speed use (entreprise) SSD. There is much much to gain by switching from mechanical to SSD than fiddling with different storage settings.

thanks for sharing

> As I have another disk for just the OS proxmox, the idea is to partition 1tb disk Hardware Raid to 500gigs LVM-thin and the other 500gigs as a normal directory then probably you need to do pvcreate /dev/sdb2 where 2 is the second partition of your disk and then create a volume group using the...

do you plan to assign public IPs to your VMs ? if yes you can create an second NIC for your VM, add it to the vmbr1 bridge and inside the VM configure it with a public IP

I had a look at this and submitted a pull request for the proxmoxer python module (which the ansible proxmox module uses in the backend) so that the root cause of the error is displayed on API calls errrors. Please rebuild the proxmoxer module using...

on a higher level, what would you like to achieve with such a script ?

when you disconnect / reconnect the cable, the cluster software should detect this and rebuild the cluster after the cable is plugged in again check that: 1) the link is active on the NIC ip link show dev your_NIC should have LOWER_UP in the output 2) if the link is active, verify if the...

@micro, can you post your vm.conf ?

if your storage is so slow that a ping request is blockend by a pending write on the storage, you should maybe start benchmarking the storage too :) Are you using VirtiO Network drivers for the VM NIC ? It would be interesting to see the vm.conf

first thanks for using fio, this a right tool for benchmarking disks concernining zfs vs ext4 performance, at the higher level, it depends on where you put the focus for your setup, ZFS is focused on data safety first. You can have checksumming and other ZFS features for free. It is exactly the...

According to upstream Qemu, the difference is in the 5 % range. If you experiment a higher difference, please share your benchmarks.

do you have configured HA ressources on this node ? remember if you have HA ressources on a node, and the node ist not in the corosync quorum partition, the ha manager will force a reboot on the host you can track such a behaviour by inspecting the pve-ha-lrm log with journalctl -u pve-ha-lrm

check that: * network connectivity is working via the vmbr0 device ( ping your gateway from the host_ * the virtual NIC of the vm is inside the vmbr0 bridge brctl show vmbr0 shoud give you a list of devices on the bridge, of the form "tapMYVMIDi0" * on the host start tcpdump on the bridge...

moving a VM from one node to another is 'migrating' the VM whether live or offline whcih migration error do you have ?

we are not involved in the development of the ansible proxmox module, did you report the issue in their bug tracker ?

usually these kind of very long accesses are non working reverse DNS lookups I don't think this is something which has to do with PVE. Or you need to run the Web server in PVE, and compare the TTFB with the web server running in the host vs web server running inside the guest.
