[ovirt-users] Monitoring UI-Plugin - Zabbix
Hi, As some of you might know I wrote a monitoring ui-plugin which displays the check results of a Nagios/Icinga monitoring solution in oVirt webadmin portal. For the next version I want to extend the functionality to also display check results of a Zabbix monitoring solution. I know that there are some people on this list who are experienced with Zabbix so I wanted to ask if there's someone who want's to help integrating Zabbix into this ui-plugin. I mostly need help understanding how Zabbix works and testing early versions (I just have a very small Zabbix monitoring environment) - fetching data from the Zabbix API and displaying it in the same way as Nagios data isn't a problem for me. So if you're willing to help please drop me an email.

I want to setup export and ISO domain on the NAS and there are no issues or questions regarding those two. I wasn't aware of any other options at the time for utilizing a local storage (since this is a shared based datacenter) so I exported a directory from each partition via NFS and it works. But I am little in the dark with the following: 1. Are there any advantages for switching from NFS based local storage to a Gluster based domain with blocks for each partition. I guess it can be only performance wise but maybe I'm wrong. If there are advantages, are there any tips regarding xfs mount options etc ? 2. I've created a volume on the FC based storage and exported it to all of the nodes in the cluster on the storage itself. I've configured multipathing correctly and added an alias for the wwid of the LUN so I can distinct this one and any other future volumes more easily. At first I created a partition on it but since oVirt saw only the whole LUN as raw device I erased it before adding it as the FC master storage domain. I've imported a few VM's and point them to the FC storage domain. This setup works, but: - All of the nodes see a device with the alias for the wwid of the volume, but only the node wich is currently the SPM for the cluster can see logical volumes inside. Also when I setup the high availability for VM's residing on the FC storage and select to start on any node on the cluster, they always start on the SPM. Can multiple nodes run different VM's on the same FC storage at the same time (logical thing would be that they can, but I wanted to be sure first). I am not familiar with the logic oVirt utilizes that locks the vm's logical volume to prevent corruption. - Fdisk shows that logical volumes on the LUN of the FC volume are missaligned (partition doesn't end on cylindar boundary), so I wonder if this is becuase I imported the VM's with disks that were created on local storage before and that any _new_ VM's with disks on the fc storage would be propperly aligned. This is a new setup with oVirt 3.4 (did an export of all the VM's on 3.3 and after a fresh installation of the 3.4 imported them back again). I have room to experiment a little with 2 of the 4 nodes because currently they are free from running any VM's, but I have limited room for anything else that would cause an unplanned downtime for four virtual machines running on the other two nodes on the cluster (currently highly available and their drives are on the FC storage domain). All in all I have 12 VM's running and I'm asking on the list for advice and guidance before I make any changes. Just trying to find as much info regarding all of this as possible before acting upon.

Personally, I believe that this is the 5th time that I have been bitten by this sanlock+gluster problem. I believe that the following are true (if not, my entire request is probably off base). * ovirt uses sanlock in such a way that when the sanlock storage is on a replicated gluster file system, very small storage disruptions can result in a gluster split-brain on the sanlock space Although this is possible (at the moment) we are working hard to avoid it. The hardest part here is to ensure that the gluster volume is properly configured. The suggested configuration for a volume to be used with ovirt is: Volume Name: (...) Type: Replicate Volume ID: (...) Status: Started Number of Bricks: 1 x 3 = 3 Transport-type: tcp Bricks: (...three bricks...) Options Reconfigured: network.ping-timeout: 10 cluster.quorum-type: auto The two options ping-timeout and quorum-type are really important. You would also need a build where this bug is fixed in order to avoid any chance of a split-brain: https://bugzilla.redhat.com/show_bug.cgi?id=1066996 It seems that the aforementioned bug is peculiar to 3-bricks setups. I understand that a 3-bricks setup can allow proper quorum formation without resorting to first-configured-brick-has-more-weight convention used with only 2 bricks and quorum auto (which makes one node special, so not properly any-single-fault tolerant). Correct. But, since we are on ovirt-users, is there a similar suggested configuration for a 2-hosts setup oVirt+GlusterFS with oVirt-side power management properly configured and tested-working? I mean a configuration where any host can go south and oVirt (through the other one) fences it (forcibly powering it off with confirmation from IPMI or similar) then restarts HA-marked vms that were running there, all the while keeping the underlying GlusterFS-based storage domains responsive and readable/writeable (maybe apart from a lapse between detected other-node unresposiveness and confirmed fencing)? We already had a discussion with gluster asking if it was possible to add fencing to the replica 2 quorum/consistency mechanism. The idea is that as soon as you can't replicate a write you have to freeze all IO until either the connection is re-established or you know that the other host has been killed. Adding Vijay. There is a related thread on gluster-devel [1] to have a better behavior in GlusterFS for prevention of split brains with sanlock and 2-way replicated gluster volumes. Please feel free to comment on the proposal there. Thanks, Vijay [1] http://supercolony.gluster.org/pipermail/gluster-devel/2014-May/040751.html One quick note before my main comment: I see references to quorum being N/2 + 1. Isn't if more accurate to say that quorum is (N + 1)/2 or N/2 + 0.5? (N + 1)/2 or N/2 + 0.5 is fine when N happens to be odd. For both odd and even cases of N, N/2 + 1 does seem to be the more appropriate representation (assuming integer arithmetic). Now to my main comment. I see a case that is not being addressed. I have no proof of how often this use-case occurs, but I believe that is does occur. (It could (theoretically) occur in any situation where multiple bricks are writing to different parts of the same file.) Use-case: sanlock via fuse client. Steps to produce originally (not tested for reproducibility, because I was unable to recover the ovirt cluster after occurrence, had to rebuild from scratch), time frame was late 2013 or early 2014 2 node ovirt cluster using replicated gluster storage ovirt cluster up and running VMs remove power from network switch restore power to network switch after a few minutes Result both copies of .../dom_md/ids file accused the other of being out of sync This case would fall under the ambit of 1. Split-brains due to network partition or network split-brains in the proposal on gluster-devel. Possible solutions Thinking about it on a systems level, the only solution I can see is to route all writes through one gluster brick. That way all the accusations flow from that brick to other bricks, and gluster will find the one file

[ovirt-users] probing peers in gluster after installing hosts
Hi all, I created 3 clusters in unique datacenter. I installed my hosts to the first one after activating the gluster service in the cluster tab. A expected otopi installed then the vdsm-gluster rpm and everything were ok for this first cluster. The other ones weren't initially gluster ready and I wanted to activate the service after installing the host (so they were without vdsm-gluster package). But checking that item didn't do anything for these hosts, so that I had to manually install vdsm-gluster package. Then, when creating a volume, the UI told me that hosts couldn't communicate. So I had to manually probe them. This leads me to that question : is it an expected behaviour? The whole gluster job (installing appropriated package and probing peers in the cluster) should be done thanks to the UI cluster tab gluster service. A last question : why isn't it possible to probe host on different clusters in the same datacenter, could be very useful. -- Nathanaël Blanchet Supervision réseau Pôle exploitation et maintenance Département des systèmes d'information 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanc...@abes.fr ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Copy/past is the best way for not having tabs instead of the correct 8 spaces before each file content instruction Ok, Thank you for the help, I will test it and send a patch. -- Nathanaël Blanchet Supervision réseau Pôle exploitation et maintenance Département des systèmes d'information 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanc...@abes.fr ___ 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 -- Nathanaël Blanchet Supervision réseau Pôle exploitation et maintenance Département des systèmes d'information 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanc...@abes.fr -- Nathanaël Blanchet Supervision réseau Pôle exploitation et maintenance Département des systèmes d'information 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanc...@abes.fr -- Nathanaël Blanchet Supervision réseau Pôle exploitation et maintenance Département des systèmes d'information 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanc...@abes.fr ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] probing peers in gluster after installing hosts
- selecting the 'enable gluster service' in later stage(after the hosts are added) doesn't do anything. As you said, this could be a nice feature though. - 'gluster peer probe' is used to form a logical cluster. I don't think having the hosts from different clusters to form a gluster-cluster is the right way.

Re: [ovirt-users] Recommended setup for a FC based storage domain
One word of caution so far, when exporting any vm, the node that acts as SPM is stressed out to the max. I releived the stress by a certain margin with lowering libvirtd and vdsm log levels to WARNING. That shortened out the export procedure by at least five times. But vdsm process on the SPM node is still with high cpu usage so it's best that the SPM node should be left with a decent CPU time amount to spare. Also, export of VM's with high vdisk capacity and thin provisioning enabled (let's say 14GB used of 100GB defined) took around 50min over a 10Gb ethernet interface to a 1Gb export NAS device that was not stressed out at all by other processes. When I did that export with debug log levels it took 5hrs :( So lowering log levels is a must in production enviroment. I've deleted the lun that I exported on the storage (removed it first from ovirt) and for the next weekend I am planing to add a new one, export it again on all the nodes and start a few fresh vm installations. Things I'm going to look for are partition alignment and running them from different nodes in the cluster at the same time. I just hope that not all I/O is going to pass through the SPM, this is the one thing that bothers me the most. I'll report back on these results next week, but if anyone has experience with this kind of things or can point to some documentation would be great. On Monday, 2.

I want to setup export and ISO domain on the NAS and there are no issues or questions regarding those two. I wasn't aware of any other options at the time for utilizing a local storage (since this is a shared based datacenter) so I exported a directory from each partition via NFS and it works. But I am little in the dark with the following: 1. Are there any advantages for switching from NFS based local storage to a Gluster based domain with blocks for each partition. I guess it can be only performance wise but maybe I'm wrong. If there are advantages, are there any tips regarding xfs mount options etc ? 2. I've created a volume on the FC based storage and exported it to all of the nodes in the cluster on the storage itself. I've configured multipathing correctly and added an alias for the wwid of the LUN so I can distinct this one and any other future volumes more easily. At first I created a partition on it but since oVirt saw only the whole LUN as raw device I erased it before adding it as the FC master storage domain. I've imported a few VM's and point them to the FC storage domain. This setup works, but: - All of the nodes see a device with the alias for the wwid of the volume, but only the node wich is currently the SPM for the cluster can see logical volumes inside. Also when I setup the high availability for VM's residing on the FC storage and select to start on any node on the cluster, they always start on the SPM. Can multiple nodes run different VM's on the same FC storage at the same time (logical thing would be that they can, but I wanted to be sure first). I am not familiar with the logic oVirt utilizes that locks the vm's logical volume to prevent corruption. - Fdisk shows that logical volumes on the LUN of the FC volume are missaligned (partition doesn't end on cylindar boundary), so I wonder if this is becuase I imported the VM's with disks that were created on local storage before and that any _new_ VM's with disks on the fc storage would be propperly aligned. This is a new setup with oVirt 3.4 (did an export of all the VM's on 3.3 and after a fresh installation of the 3.4 imported them back again). I have room to experiment a little with 2 of the 4 nodes because currently they are free from running any VM's, but I have limited room for anything else that would cause an unplanned downtime for four virtual machines running on the other two nodes on the cluster (currently highly available and their drives are on the FC storage domain). All in all I have 12 VM's running and I'm asking on the list for advice and guidance before I make any changes. Just trying to find as much info regarding all of this as possible

If the former, should we keep the look and feel the same with the oVirt website? Great! I have some suggestions. 1. If it is possible, we'd better rent a (virtual/cloud) server inside China. Sometimes it's very slow to access ovirt.org. Maybe we can also have a sub-domain name such as cnuser.ovirt.org, and make the outlook of cnuser the same as oVirt main site. 2. Considering the content, we can start by translating primary pages and slides in ovirt.org. I think in China most of the technical people are able to read English, so it is not necessary to translate all the pages. We shall then provide new content that is different from the oVirt main site.

After that reactivate the host and proceed to the next one. One caveat found: chkconfig glusterd on isn't executed. You'll need to do that by hand and also start the service or restart the server while in maintenance mode. Joop ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[ovirt-users] Adding Fedora 20 Support
Hello, I recently came across the LWN article on oVirt 3.4 (http://lwn.net/SubscriberLink/600370/dfa9cdd4f5ee0bb3/) and was discussing the lack of Fedora 20 support with an oVirt contributor, bkp. It's been 4 months since I last looked at running oVirt. I use Fedora 20 on all of my infrastructure, so I was quite surprised that there is still not support for running the engine on F20. Anyways, rather than just complaining, I figured it would be more helpful to volunteer some time to fix the issue. 1) I've tried looking through the oVirt bug reports to see what's happening with Fedora 20. So far, I have identified three issues that prevent 3.4 from working. Fedora includes sos-3, sos doesn't have support for all ovirt plugins, and only has Wildfly instead of JBoss-as. The full list of bugs is listed in https://bugzilla.redhat.com/show_bug.cgi?id=1060198. 2) I was looking through the various oVirt yum repositories and noticed that oVirt provides JBoss-AS along with tons of packages for the el6 platform; however, for both Fedora 19 and 20, oVirt almost entirely uses built-in packages. This seems like strange behavior where the project has gone to great lengths to make sure oVirt works on platforms with outdated or nonexistent packages, but won't override or use alternates on platforms that contain overly new packages. Could someone explain why oVirt doesn't package these for Fedora, particularly jboss-as? 3) I'm not making accusations or trying to cause trouble, but could someone explain to an outsider what happened with Fedora 20 support? oVirt is a complicated project to say the least and, after a brief look at some of the RPMs last night, the packages are just as complex. Basically, I'm trying to figure out if there were some intractable problems that prevented oVirt from -- more or less -- shipping tweaked Fedora 19 dependencies for oVirt on Fedors 20, or whether it was more a lack of manpower, a lack of interested user base, or perhaps I'm just getting started on digesting the packages, but I think it should be feasible to pull the problematic packages from F19, tweak them to ovirt-* versions (eg. ovirt-sos), and tweak the oVirt packages to use the non-system paths for those packages. Publish the whole thing through COPR, and if oVirt is happy with the results, merge them into the official packages and repository. I know that there will be some apprehension about the project taking on maintaining these dependency packages, but I'm looking to get 3.4 working on Fedora 20 as a stopgap until 3.5 is released with support for native packages.

This seems like strange behavior where the project has gone to great lengths to make sure oVirt works on platforms with outdated or nonexistent packages, but won't override or use alternates on platforms that contain overly new packages. Could someone explain why oVirt doesn't package these for Fedora, particularly jboss-as? 3) I'm not making accusations or trying to cause trouble, but could someone explain to an outsider what happened with Fedora 20 support? oVirt is a complicated project to say the least and, after a brief look at some of the RPMs last night, the packages are just as complex. Basically, I'm trying to figure out if there were some intractable problems that prevented oVirt from -- more or less -- shipping tweaked Fedora 19 dependencies for oVirt on Fedors 20, or whether it was more a lack of manpower, a lack of interested user base, or perhaps I'm just getting started on digesting the packages, but I think it should be feasible to pull the problematic packages from F19, tweak them to ovirt-* versions (eg. ovirt-sos), and tweak the oVirt packages to use the non-system paths for those packages. Publish the whole thing through COPR, and if oVirt is happy with the results, merge them into the official packages and repository. yes, should be feasible just using the 'blob' approach of the .el6 jboss-as rpm for fedora 20, which is the current plan. we'd love help with doing/testing this of course. I know that there will be some apprehension about the project taking on maintaining these dependency packages, but I'm looking to get 3.4 working on Fedora 20 as a stopgap until 3.5 is released with support for native packages. Thoughts? Thanks, Justin ___ 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

OK I think I go the problem fixed. I stopped a VM that had the Blank template, exported it, reimported it. Now im able to live migrate disks with no issue.
