similar to: Live migration using shared storage in different networks

Hi! I am about to deploy a virtualisation cluster based on a storage server with 10 Gbps interfaces for iSCSI and two computing nodes running VMs in KVM that will access the storage via the 10 Gbps network. I am trying to find real use cases of people using CentOS 6 as an iSCSI target but can't find any. Anyone using a configuration similar to this one? Thanks in advance! Miguel

That makes for an interesting problem. I cannot open port 24007 to allow RPC access.

I am running gluster 3.8.9 and trying to setup a geo-replicated volume over ssh, It looks like the volume create command is trying to directly access the server over port 24007. The docs imply that all communications are over ssh. What am I missing? -- Alvin Starr || land: (905)513-7688 Netvel Inc. || Cell: (416)806-0133 alvin at netvel.net

Hi Alvin, Yes, geo-replication sync happens via SSH. Ther server port 24007 is of glusterd. glusterd will be listening in this port and all volume management communication happens via RPC.

I was sort of hoping that is was something simple like setting the "do_the_right_thing" flag.

I am afraid of lvm going to disk failure. So if I have 2 disk and one crashes, I thing all LVM goes bad! So, I have decided to used individual disk.

Hi, Can you tell why my vnic built on top of an aggregation of 2 NICs of 1 Gbit/s doesn''t report a speed of 2 GBit/s ? [root at nazgul /]# dladm show-dev bge0 link: up speed: 1000Mb duplex: full bge1 link: down speed: 0Mb duplex: unknown bge2 link: down speed: 0Mb duplex: unknown bge3 link: down speed: 0Mb

This is not abit issue just a minor annoyance. I use Foreman to provision my systems and to keep control I remove all the default *.repo files andkeep away from installing more *.repo files so I can control the content via the foreman(katello) provided redhat.repo. I would argue that the *-release-*.rpm should not contain any setup code but just the stuff in /etc/yum.repos.d. -- Alvin

FIrstly Centos is primarily a RHEL clone. This means that the primary design decisions are to be as RHEL like as possible. After that there are additions and upgrades. Secondly Fedora does not actively support Xen. As a long time Xen and RH/Fedora user I have spent lots of time building/rebuilding broken/missing packages in Fedora. Quite frankly Xen under Fedora is somewhat broken. Libvirt

I have done that, but the point of the request is that we would like to have an official upstream AMI that we can use as the basis for our work. I'm guessing that the reason for the blacked out instance type is that early 6.x kernels didn't have the patches necessary to support 36 vCPU's present in the c4.8xlarge instance.

One of the things suboptimal with Marketplace images is that the author can limit which instance types are allowed with the AMI and there is no way to override that. We are using Centos 6.8 for our deployments, but we need to move to the c4.8xlarge type, but that is not a permitted option for the "CentOS 6 (x86_64) - with Updates HVM" AMI. Is there any way we could get that image

Hi Michal, Thanks for your answer. I don’t understand why an interface created without mtu gets only 1500 visible in the virtual machine but if I create an interface with mtu higher than 1500 e.g. 2000 the bridge will change too. Before the bridge was e.g. by 9000. I ask because you wrote if I don’t set an mtu of the interface I will get the mtu of the bridge. But it seems so. Can you clarify

In general if no MTU is set on interface creation the default value is 1500. On OVS the bridge MTU is automatically set to the smallest port MTU. So you just have to set the MTU of each port of the bridge. Take a look at: https://bugzilla.redhat.com/show_bug.cgi?id=1160897 It is a bit of a pain to read but seems to confirm the statement about the OVS MTU value being set by the MTU of the
