vdsm (4.1) restarts glusterd when activating a node, even if it's already running
by Darrell Budic 02 Jul '17

02 Jul '17

Upgrading some nodes today, and noticed that vdsmd restarts glusterd on a node when it activates it. This is causing a short break in healing when the shd gets disconnected, forcing some extra healing when the healing process reports “Transport Endpoint Disconnected” (N/A in the ovirt gui). This is on a converged cluster (3 nodes, gluster replica volume across all 3, ovirt-engine running elsewhere). Centos 7 install, just upgraded to Ovirt 4.1.2, running cluster 3.10 from the Centos SIG. The process I’m observing: Place a node into maintenance via GUI Update node from command line Reboot node (kernel update) Watch gluster heal itself after reboot Activate node in GUI gluster is completely stopped on this node gluster is started on this node healing begins again, but isn’t working “gluster vol heal XXXX info” reports this node’s information not available because “Transport endpoint not connected”. This clears up in 5-10 minutes, then volume heals normally Someone with a similar setup want to check this and see if it’s something specific to my nodes, or just a general problem with the way it’s restarting gluster? Looking for a little confirmation before I file a bug report on it. Or a dev want to comment on why it stops and starts gluster, instead of a restart which would presumably leave the brick processes and shd running and not causing this effect? Thanks, -Darrell

Each Hypervisor has HBA controller and Data CLutser has four Storage named: DATA_FC, DATA_NFS, EXPORT and ISO-DOMAIN. Anybody know how can I extend a DATA_FC ? Which is the best practies ? Extend LUN from HP MSA controller or adding a new lun ? if I extend lun inside HP MSA oVirt see the new size ? Enrico Thanks a lot. Best Regards

Recovering hosted-engine

--------=_MB617458AF-4FCC-4AB6-8A34-3338D99C6BB8 Content-Type: text/plain; format=flowed; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi A couple of questions about hosted-engine recovery. Part way through this URL, in the section "Workflow for Restoring the=20 Self-Hosted Engine Environment" http://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restorin= g_an_EL-Based_Self-Hosted_Environment/ it looks like once the hosted-engine is recovered on Host 1, the VMs on=20 Host 2 and 3 will be running, but not accessible to the recovered Hosted=20 Engine. Is that correct? If so, how to you remove host 2 and host 3 from the environment, then=20 add back in again while keeping the VMs running? Host 2 and Host 3 are not recoverable in their current state. These=20 hosts need to be removed from the environment, and then added again to=20 the environment using the hosted-engine deployment script.

oVirt Node update not updating kernel, glibc, etc
by Mike DePaulo 02 Jul '17

02 Jul '17

Hi, I installed 3 ovirt 4.1.1 nodes in early May. Today used oVirt's webgui to update ("Upgrade") 2 of them. They are both reporting oVirt Node 4.1.2 & vdsm-4.19.15-1.el7.centos now. However, it appears that the kernel was not updated: [root@death-star peers]# uname -a Linux death-star 3.10.0-514.16.1.el7.x86_64 #1 SMP Wed Apr 12 15:04:24 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux And neither was glibc The installed version is still 2.17-157.el7_3.1 rather than 2.17-157.el7_3.4 . The following lines were appended to /var/log/yum.log: Jul 01 18:47:49 Installed: ovirt-node-ng-image-4.1.2-1.el7.centos.noarch Jul 01 18:50:27 Installed: ovirt-node-ng-image-update-4.1.2-1.el7.centos.noarch Jul 01 18:50:27 Erased: ovirt-node-ng-image-update-placeholder-4.1.1.1-1.el7.centos.noarch Thanks in advance, -Mike

Re: [ovirt-users] [ovirt-devel] problem about vm in ovirt node can ping node, but cannot ping gateway or the third host in LAN
by Edward Haas 01 Jul '17

01 Jul '17

If I understood correctly, you are using a nested solution where the node is itself a VM. If this is the case, you may have a security feature active on the physical host/node. In oVirt we have the default filter which allows only a single source mac to exit the vNIC, but you disabled it. I guess you should have something similar on the upper node. Please note that such topics fit the user list, not devel. Thanks, Edy.

HostedEngine VM not visible, but running
by cmc 30 Jun '17

30 Jun '17

Hi, I've migrated from a bare-metal engine to a hosted engine. There were no errors during the install, however, the hosted engine did not get started. I tried running: hosted-engine --status on the host I deployed it on, and it returns nothing (exit code is 1 however). I could not ping it either. So I tried starting it via 'hosted-engine --vm-start' and it returned: Virtual machine does not exist But it then became available. I logged into it successfully. It is not in the list of VMs however. Any ideas why the hosted-engine commands fail, and why it is not in the list of virtual machines? Thanks for any help, Cam
