Is it possible that the root filesystem ist not an image file and the files are accessible like in former times with OpenVZ? So we could simple mount a NFS volume that hosts the root filesystems?

This is not what we need. The Image file on NFS is for sure possible and working. We like to use real nfsroot like KVM with pxeboot.

Is it possible to boot the LXC containers from nfsroot instead of a block device?

As i said we have a NetApp MetroCluster so all writes are commited synchronous to both sides. So storage is no problem. The switchover takes less than 60s. Whats about a tiebraker with LTE or something like this. So we could check if one site is down because of a power problem or something like...

Latency is no problem we have ultra low latency switches. Here you see latency to local and remote datacenter. We have now 20GBit between the DCs and we will add 2 more links to get 40GBit. This should be enough. 64 bytes from raptor3.dmz.cubit.at (192.168.61.217): icmp_seq=1 ttl=255...

Any ideas? I found nothing in the documentation. Lets say we have following situation: DC1: 2 Proxmox nodes, NetApp Metrocluster Site A DC2: 2 Proxmox nodes, NetApp Metrocluster Site B So we have a cluster with 4 nodes. All should be ok. But then DC1 is going down. No connectivity to the...

Hello, we like to build up a new cluster distributed over two datacenters. We use a NetApp Metrocluster and connect the storage with NFS. So storage is no problem. In normal situation there should be at least 3 nodes. How many nodes are needed in a cluster distributed over two datacenters...

You can use two default gateways but then you have round robin for the gateways if they have the same metric. For sure you have multiple routing tables too but this will be a very complicated setup.

You can only have one default gateway. But you can define routes to specific networks over an other gateway.

Looks good now The x710 are working now

There is a known bug with bonding. I have the same problem. I hope this problem will be solved soon. https://bugzilla.proxmox.com/show_bug.cgi?id=1343

When can we expect the new pve-kernel?

Which is the correct way to change the mtu of a bridge or a internal port to mtu 9000? I can set the ports in the bond to mtu9000 but not the bridge or the vlan. ovs-vsctl set int vlan50 mtu_request=9000 or ovs-vsctl set int vmbr1 mtu_request=9000 does set the request size but mtu is...

i tried ip link too but same problem ip link set mtu 9000 dev eth3 ip link set mtu 9000 dev eth7 ip link set mtu 9000 dev bond0 RTNETLINK answers: Invalid argument

I have the problem that i can set the MTU 9000 und the physical interfaces (x710) but i can't set the mtu on the ovs bond. allow-vmbr1 bond0 iface bond0 inet manual ovs_bonds eth3 eth7 ovs_type OVSBond ovs_bridge vmbr1 pre-up ( ifconfig eth3 mtu 9000 && ifconfig eth7 mtu...

I have installed system on single SSD. The storage is coming from a NetApp MetroCluster with NFS. Who cares if one node is failing as long as you have enough resources to restart the vms of the dead host.

I would check /var/logs Btw where are you storing the vms and iso and so on?

In memory databases are a real pain. Even if you have a backup you still don't have an working ha solution without dataloss. Think about a crash of one hypervisor. Everything is RAM is lost. I don't understand why people use in memory databases for production. Why not using big caches in RAM...

Did you work with this document? https://library.netapp.com/ecm/ecm_download_file/ECMP1532526

Ah ok the E-Series. Then you need to connect the servers with FC. Do you have FC switches? You need to create an LUN to access to the data. The E-Series is a fast block-only storage and very different to the FAS systems.
