Re: [ovirt-users] oVirt node, hosted-engine, oVirt appliance and cloud-init
Hi First of all I think cloud-init is optional so user can select if use it or not. So if somebody wants to deploy hosted engine the hard way by installing it on OS , its his choice allowed too. For our appliance I dont think we need anything except for root password. Last option is in case somebody have some complicated net config he needs to implement in the engine VM on the first run we should allow him the option to provide the cloud-init iso by himself and he can define all he wants there.

Deploying the engine as an appliance is indeed a good way to speed up and make easier the hosted-engine deployment: you don't need to install an OS on the engine virtual machine and than install the engine and so on but you could simply run a ready to use oVirt engine appliance. But you still need to configure it and so cloud-init support within hosted-engine is a reasonable way to complement it. Then we could also integrate it with oVirt node to let the user input the required info from node TUI in order to have an almost unattended hosted-engine setup on oVirt node using an engine appliance with cloud-init. The idea is to collect the required information interactively from hosted-engine setup or from node TUI (passing them to hosted-engine setup via an answer file) and pass them to the appliance via cloud-init using a no-cloud datasource. So now the question is what do you really want to configure via cloud-init? It's just to define what we want in order to be more focused on user needs: for instance we could configure engine VM instance hostname, we could set the root password, we could create other users, we could upload ssh private keys, we could run a command on the first boot and so on. So, if you have any ideas or requirement about that it's the right time for it. thanks, Simone ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Each glusterd maintains its copy of volume and peer configuration under /var/lib/glusterd. * /var/lib/glusterd/peers - Holds one file for every peer, excluding 'self'.

For other files under /var/lib/glusterd that are empty, we could use the fact that each node has a copy of the configuration and it can be used to reconstruct.

Re: [ovirt-users] Communication errors between engine and nodes?
We are observing the same thing with our oVirt environment. At random moments (could be a couple of times a day , once a day or even once every couple of days), we receive the VDSNetworkException message on one of our nodes. Haven't seen the heartbeat exceeded message, but could be that I overlooked it within our logs. At some rare occasions, we also do see Host cannot access the Storage Domain(s) UNKNOWN attached to the Data Center, within the GUI. VM's will continue to run normally and most of the times the nodes will be in UP state again within the same minute. Will still haven't found the root cause of this issue. Our engine is CentOS 6.6 based and it's happing with both Centos 6 and Fedora 20 nodes. We are using a LCAP bond of 1Gbit ports for our management network. As we didn't see any reports about this before, we are currently looking if something network related is causing this. -Oorspronkelijk bericht- Van: users-boun...@ovirt.org [mailto:users-boun...@ovirt.org] Namens Chris Adams Verzonden: 12 March 2015 14:23 Aan: users@ovirt.org Onderwerp: Re: [ovirt-users] Communication errors between engine and nodes? Once upon a time, Lior Vernia lver...@redhat.com said: If I'm not mistaken, heartbeat intervals are configured to 10 seconds by default. Okay, thanks. The command times out queries for the status of VMs on a host - any reason to suspect why that's taking long? Does it happen on specific hosts? No idea. It seemed to happen on node5 a bunch over a week, but then there were errors on other nodes as well. It isn't always Heartbeet exceeded, sometimes it is VDSNetworkException: Message timeout which can be caused by communication issues. I haven't been able to find any network issues that could cause this (no errors logged anywhere). There doesn't seem to be any pattern to when it happens either. The log entry I posted was from 04:42 local time, and a bunch of the VMs are CentOS 5, which does log rotation at 04:00 by default (which can spike the CPU and disk I/O), but they are all done long before 04:42. It happened in the middle of the afternoon a couple of days ago, while I was logged-in to the web UI, and I didn't notice any unusual behavior. One other odd thing: I have also been experiencing an issue where I randomly get logged out of the web UI. Usually nothing else was going on, but a couple of times it seemed to correspond with one of the node errors (hard to tell). It looked like the same error as BZ 1198493 (I'd see a bunch of Failed to log User null@N/A out messages). I don't know if these issues are related or that was just coincidence. To try to rule out any unseen network issues, I started an fping to all seven nodes and the engine from another physical system on the same VLAN. It is sending one ping to each of the eight hosts every 0.2 seconds. That has not shown a dropped packet since I started yesterday afternoon. However, during that time, I also have not seen any engine/vdsm timeouts. I was going to say I had not been logged out of the web UI, but that just happened while I was typing the previous sentence. -- Chris Adams c...@cmadams.net ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
