Re: [ovirt-users] Recovering hosted-engine

Hi Didi Fair enough. If I'm in this situation..... I have 3 hosts with 6 production VMs. The hosted-engine VM is completely toast and not recoverable. However I have a backup of the hosted-engine database (do I need anything else). Is it possible to build a new VM, import the backup of the previous hosted-engine database and reconnect the storage domains and VMs in their running state without any VMs experiencing an outage? The URL http://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restorin… looks to be longer now. I'll review, test and see if this will give me what I'm looking for. The broken link still seems to be broken. When I click the link, the browser ends up at this http://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restorin… But I suspect it should be http://www.ovirt.org/documentation/self-hosted/chap-Installing_Additional_H… Kind regards Andrew ------ Original Message ------ From: "Yedidyah Bar David" <didi(a)redhat.com> To: "Andrew Dent" <adent(a)ctcroydon.com.au> Cc: "users" <users(a)ovirt.org> Sent: 3/07/2017 11:12:05 PM Subject: Re: [ovirt-users] Recovering hosted-engine >On Mon, Jul 3, 2017 at 3:46 PM, Andrew Dent <adent(a)ctcroydon.com.au> >wrote: >> Has anyone successfully completed a hosted-engine recovery on a >>multiple >> host setup with production VMs? > >I'd like to clarify that "recovery" can span a large spectrum of >flows, from a trivial "I did some change to the engine database >that broke stuff and I want to restore a backup I took prior to >this change" to a full system restoration including purchasing >and deploying new (perhaps different) hosts/network/storage >hardware, including many other flows in between. > >So when you plan for recovery, you should define very well what >flows you plan to handle, and how you handle each. > >The linked procedure correctly says it's "providing an example". > >> >> Kind regards >> >> >> Andrew >> >> >> >> ------ Original Message ------ >> From: "Andrew Dent" <adent(a)ctcroydon.com.au> >> To: "users" <users(a)ovirt.org> >> Sent: 2/07/2017 2:22:16 PM >> Subject: [ovirt-users] Recovering hosted-engine >> >> Hi >> >> A couple of questions about hosted-engine recovery. >> Part way through this URL, in the section "Workflow for Restoring the >> Self-Hosted Engine Environment" >> >>http://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restorin… >> it looks like once the hosted-engine is recovered on Host 1, the VMs >>on Host >> 2 and 3 will be running, but not accessible to the recovered Hosted >>Engine. >> Is that correct? > >I am pretty certain that the procedure assumed that all hosts need >restoration, >not that some are still up-and-running. > >> If so, how to you remove host 2 and host 3 from the environment, then >>add >> back in again while keeping the VMs running? > >That's a good question. > >Please try to describe the exact flow you have in mind.

Virtual Machine looses connectivity with no clear explanation

This is a multi-part message in MIME format. --------------CA6FA101A23C7121C82BF9C5 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit I have a rather strange issue which is affecting one of my last deployed Hypervisors. It is a CentOS 7 (not a oVirt Node) which runs only 3 Virtual Machines. One of these VMs have a reasonable output traffic at peaks (500 - 700Mbps) and the hypervisor underneath is connected to the switch via a bonding (mode=2) which in turn creates bond0.XX interfaces which are connected to different bridges for each network. The VM in question is connected to bridge "ovirtmgmt". When the problem happens the VM stops passing traffic and cannot reach even the router or other VMs in the same Layer 2. Seems the bridge stop passing traffic for that particular VM. Other VMs work fine since they were created. When this problem happens I just need to go to its Console and run a reboot (Ctrl-Alt-Del), don't even need to Power Off and Power On again using oVirt Engine. I have even re-installed this VMs operating system from scratch but the problem persists. Have also changed the vNic mac address in the case (already check) of conflicted mac addresses somewhere in that Layer 2. Last, my hypervisor machine (due a mistake) has been running with SElinux disabled, not sure if it could have anything to do with this behavior. Anyway, anyone has ever seen any behavior like that ?

Gluster issue with /var/lib/glusterd/peers/<ip> file
by Mike DePaulo 03 Jul '17

03 Jul '17

Hi everyone, I have ovirt 4.1.1/4.1.2 running on 3 hosts with a gluster hosted engine. I was working on setting up a network for gluster storage and migration. The addresses for it will be 10.0.20.x, rather than 192.168.1.x for the management network. However, I switched gluster storage and migration back over to the management network. I updated and rebooted one of my hosts (death-star, 10.0.20.52) and on reboot, the glusterd service would start, but wouldn't seem to work. The engine webgui reported that its bricks were down, and commands like this would fail: [root@death-star glusterfs]# gluster pool list pool list: failed [root@death-star glusterfs]# gluster peer status peer status: failed Upon further investigation, I had under /var/lib/glusterd/peers/ the 2 existing UUID files, plus a new 3rd one: [root@death-star peers]# cat 10.0.20.53 uuid=00000000-0000-0000-0000-000000000000 state=0 hostname1=10.0.20.53 I moved that file out of there, restarted glusterd, and now gluster is working again. I am guessing that this is a bug. Let me know if I should attach other log files; I am not sure which ones. And yes, 10.0.20.53 is the IP of one of the other hosts. -Mike

Other portals work, user portal experiences console errors
by Sophia Valentine 03 Jul '17

03 Jul '17

Hi all! I installed the nightly from the repo on CentOS 7.0. I currently have an issue where visiting the user portal triggers the following errors in the browser console. I believe that I will need to compile the engine from source due to the current source being compacted, thus obscuring the stacktrace. If that is needed, can I generate an RPM with the debug build I create (might need some help with this, if that's okay)? I'm hoping it's a "known error" and that there's a simple fix. Would love to get to the bottom of this! Thanks.

Gluster storage network not being used for Gluster
by Mike DePaulo 03 Jul '17

03 Jul '17

Hi, I configured a "Gluster storage" network, but it doesn't look like it is being used for Gluster. Specifically, the switch's LEDs are not blinking, and the hosts' "Total Tx" and "Total Rx" counts are not changing (and they're tiny, under 1 MB.) The management network must still be being used. I have 3 hosts running oVirt Node 4.1.x. I set them up via the gluster hosted engine. The gluster storage network is 10.0.20.x. These are the contents of /var/lib/glusterd/peers: [root@centerpoint peers]# cat 8a83fddd-df7e-4e3b-9fc7-ca1c9bf9deaa uuid=8a83fddd-df7e-4e3b-9fc7-ca1c9bf9deaa state=3 hostname1=death-star.ad.depaulo.org hostname2=death-star hostname3=192.168.1.52 hostname4=10.0.20.52 [root@centerpoint peers]# cat b6b96427-a0dd-47ff-b3e0-038eb0967fb9 uuid=b6b96427-a0dd-47ff-b3e0-038eb0967fb9 state=3 hostname1=starkiller-base.ad.depaulo.org hostname2=starkiller-base hostname3=192.168.1.53 Thanks in advance, -Mike

vdsm changing disk scheduler when starting, configurable?
by Darrell Budic 03 Jul '17

03 Jul '17

It seems vdsmd under 4.1.x (or something under it’s control) changes the disk schedulers when it starts or a host node is activated, and I’d like to avoid this. Is it preventable? Or configurable anywhere? This was probably happening under earlier version, but I just noticed it while upgrading some converged boxes today. It likes to set deadline, which I understand is the RHEL default for centos 7 on non SATA disks. But I’d rather have NOOP on my SSDs because SSDs, and NOOP on my SATA spinning platters because ZFS does it’s own scheduling, and running anything other than NOOP can cause increased CPU utilization for no gain. It’s also fighting ZFS, which tires to set NOOP on whole disks it controls, and my kernel command line setting. Thanks, -Darrell

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

by Enrico Becchetti Gmail 02 Jul '17

02 Jul '17

Dear All, I've oVirt 3.5.3-1-1.el6 with two kind of storage , NFS and Fibre Channel. 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
