Adding arbiter to hyperconverged setup
by Simon Nussbaum 27 Sep '18

27 Sep '18

Dear all We are very happily running a hyperconverged gluster ovirt setup since beginning of 2016. Because we couldn't afford 3 well-equipped servers, we've set-up replica 3 with one arbiter gluster cluster. Back then the gluster integration in oVirt wasn't where it is today. We did not add the arbiter node to oVirt. Since then a lot changed and we suspect that from time to time we run into problems because we haven't added the arbiter node as a host to oVirt. We also think that we may profit from features and higher visibility in oVirt when it is aware of all gluster nodes. Now, we are thinking of adding the third, the arbiter host. Today we are using oVirt 4.2.0.2 and GlusterFS 3.12 on CentOS 7.4. We see two ways to accomplish this: 1) Add it as a new host 2) Import it as the discovered host in Compute >> Clusters >> OurCluster The questions we have: * First of all, is this a good idea anyway? * Do we need to install vdsmd on the arbiter node? * What is or is there difference between the two ways? Will it discover the gluster configuration or break it? Before we break it we would love to hear what you guys think. Thanks a lot Simon

I think I've just found the answer myself: https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.3/h… https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.4/h… But any inputs to my previous questions are still very welcome.

Ovirt attach serial port on VM
by Alex K 27 Sep '18

27 Sep '18

Hi all, I have a serial port on one of the servers where the guest VM is running. setserial -g /dev/ttyS0 /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 I wanted the serial port to be connected at the VM, so as the VM to be able to use directly the serial port of the server. Thus I went at host devices to add the port but I am not able to find it, as the serial port is not listed at PCI devices. I recall that on plain KVM one could be able to attach such a serial port at a guest VM. Has anyone been able to attach a serial port to a guest VM woth ovirt? (I am running 4.2.5) Thanx, Alex
