[ovirt-users] oVirt nodes with local storage
On the weekend I upgraded my self-hosted oVirt engine to 4.56. All went well with that! I also spotted that there was an update for all my 4.54 nodes, but something has changed with the repo overnight because none of my nodes see updates anymore, though the update remains available here … https://resources.ovirt.org/pub/ovirt-4.5/iso/ovirt-node-ng-installer/. Yesterday, I attempted to update just one of my nodes and ran into this snag… “Local storage domains were found on the same filesystem as / ! Please migrate the data to a new LV before upgrading, or you will lose the VMs”. I’ve always stored my VMs in a separate /DATA directory off the root filesystem, and shared the local storage using NFS. I know it’s not ideal, but with good frequent regular backups, it has served me well for many years. A Google search revealed, that others have also had similar local storage issues, and suggestions on ways to mitigate the issue, including the oVirt documentation found here… https://www.ovirt.org/documentation/upgrade_guide/index.html#Upgrading_hypervisor_preserving_local_storage_4-3_local_db, is not my preferred fix. In the past node updates with my local storage were not a problem and were easy peasy! From some of the discussions I saw at Red Hat, I have deduced (maybe wrongly) that there was an issue that necessitated a fix, which introduced a required check for local storage during the upgrade process. I probably should move all the local storage off the oVirt nodes, but at this time, that is easier said than done. I’m posting here only to see if there are perhaps other ideas or perspectives I may not have thought of and should consider with my local storage. Thank you all in advance, much appreciated, and of course, thank you all for supporting oVirt! ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/YR23KNJSUXH4DSAKTC3KEUKEC7V54VD6/
[ovirt-users] oVirt Nodes 'Setting Host state to Non-Operational' - looking for the cause.
2 days ago I found that 2 of the 3 oVirt nodes had been set to 'Non-Operational'. GlusterFS seemed to be ok from the commandline, but the oVirt engine WebUI was reporting 2 out of 3 bricks per volume as down and event logs were filling up with the following types of messages.

Moved any VM disks using Storage Domain data03 onto other Storage Domains. 2. Placed data03 Storage Domain ionto Maintenance mode. 3. Placed host03 into Maintenance mode, stopping Gluster services and rebooting. 4. Ensuring all Bricks were up, the peers connected and healing started. 5. Once Gluster volumes were healed I activated host03, at which point host01 also activated. 6. Host01 was showing as disconnected on most bricks so I rebooted it which resolved this. 7. I activated Storage Domain data03 without issue. The system has been left for 24hrs with no further issues. The issue is now resolved but it would be helful to know what happened to cause the issues with the Storage Domain data03 and where do I look to confirm.

[ovirt-users] oVirt nodes not responding
Hi everyone, we have an oVirt-Cluster with 5 nodes and 3 of them provide the storage with GlusterFS and replica 3. The cluster is running 87 VMs and has 9TB storage where 4TB is in use. The version of the oVirt-Engine is 4.1.8.2 and GlusterFS is 3.8.15. The servers are running in a HP bladecenter and are connected with 10GBit to each other. Actually we have some problems that all ovirt nodes periodically won't respond in the cluster with the following error messages in the oVirt webinterface: VDSM glustervirt05 command GetGlusterVolumeHealInfoVDS failed: Message timeout which can be caused by communication issues Host glustervirt05 is not responding. It will stay in Connecting state for a grace period of 68 seconds and after that an attempt to fence the host will be issued. Host glustervirt05 does not enforce SELinux. Current status: PERMISSIVE Executing power management status on Host glustervirt05 using Proxy Host glustervirt02 and Fence Agent ilo4:xxx.xxx.xxx.xxx. Manually synced the storage devices from host glustervirt05 Status of host glustervirt05 was set to Up. In the vdsm logfile I can find the following message: 2019-11-26 11:18:22,909+0100 WARN (vdsm.Scheduler) [Executor] Worker blocked: timeout=60, duration=180 at 0x316a6d0> task#=2859802 at 0x1b70dd0> (executor:351) And I figured out, that the gluster heal info command takes very long: [root@glustervirt01 ~]# time gluster volume heal data info Brick glustervirt01:/gluster/data/brick1 Status: Connected Number of entries: 0 Brick glustervirt02:/gluster/data/brick1 Status: Connected Number of entries: 0 Brick glustervirt03:/gluster/data/brick2 Status: Connected Number of entries: 0 real 3m3.626s user 0m0.593s sys 0m0.559s A strange behavier is also that there is one virtual machine (a postgresql database) which stops running unexpectedly every one or two days ... The only thing that has been changed on the vm in the least past was a resize of the disk. VM replication-zabbix is down with error. Exit message: Lost connection with qemu process. And when we add or delete a larger disk with approximately 100GB in glusterfs, the glusterfs cluster freaks out won't respond anymore. This also results in paused VMs ... Has anyone an idea what could cause such problems? ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/PT2LS4YLJMPY22IAVFA723HGPJ5PXPAG/

Re: [ovirt-users] Ovirt nodes NFS connection
Hello Tal It seems you have a very big overkill on your environment. I would say that normally 2 x 10Gb interfaces can do A LOT for nodes with proper redundancy. Just creating Vlans you can separate traffic and apply, if necessary, QoS per Vlan to guarantee which one is more priority. If you have 2 x 10Gb in a LACP 802.3ad Aggregation in theory you can do 20Gbps of aggregated traffic. If you have 10Gb of constant storage traffic it is already huge, so I normally consider that Storage will not go over a few Gbps and VMs another few Gb which fit perfectly within even 10Gb The only exception I would make is if you have a very intensive (and I am not talking about IOPS, but throughput) from your storage then may be worth to have 2 x 10Gb for Storage and 2 x 10Gb for all other networks (Managment, VMs Traffic, Migration(with cap on traffic), etc).

Re: [ovirt-users] oVirt Nodes Monitoring
Hi, You can also monitor by enabling SNMP in Hosts. For this purpose, using the MIB, you need to build a Zabbix Template as detailed in the link here https://github.com/jensdepuydt/zabbix-ovirt We are monitoring Version Hosts with CentOS 7 and oVirt 4.0.x using this method. I will share the Zabbix-Template, we have built tomorrow as I, at the moment do not have access to my resources. -- Thanks & Regards, Anantha Raghava eXzaTech Consulting And Services Pvt. Ltd.

Re: [ovirt-users] Ovirt Nodes - Which OS
RHEL / CentOS 7 Are currently recommended, amongst others for Ovirt4. You're getting the packages from ovirt's repository not the distro base so no need to worry that one distro or another is behind which would most likely be the case if you were getting base packages.

Re: [ovirt-users] oVirt nodes
Hello, official numbers would also be interesting to me. I can tell you that we do have some larger infrastructures running on several engine hosts, one of them for example has 3 datacenters, 7 cluster, 200 hosts. We do have noticeable performance issues on the engine host. The engine is already running on rather performant hardware including 12 cores and SSDs - but nevertheless we have load averages >20 on it and very slow response time from the engine itself. best, Dominique Taffin Systemadministrator IT Operations Platform Core Services 1&1 Internet SE | Brauerstraße 48 | 76135 Karlsruhe | Germany Phone: +49 721 91374-3912 E-Mail: dominique.taf...@1und1.de | Web: www.1und1.de Hauptsitz Montabaur, Amtsgericht Montabaur, HRB 24498 Vorstand: Christian Bigatà Joseph, Robert Hoffmann, Hans-Henning Kettler, Uwe Lamnek Aufsichtsratsvorsitzender: Michael Scheeren Member of United Internet Diese E-Mail kann vertrauliche und/oder gesetzlich geschützte Informationen enthalten.

[ovirt-users] Ovirt nodes lose up status
Hello, I am experiencing an issue with on my current ovirt DC. The setup is 2 machines running Ovit Nodes connected to a LaCie 12big Rack Fibre 8, the nodes are connected to both controllers.. This configuration has worked fine for a couple of weeks. Recently the nodes go from Up status to Non Operational. When I activate them back they don't last more than 2 minutes. /var/logl/messages on both nodes shows the same errors : Jul 23 15:14:58 localhost kernel: device-mapper: table: 253:0: adding target device sdc caused an alignment inconsistency: physical_block_size=4096, logical_block_size=512, alignment_offset=170496, start=0 Jul 23 15:14:58 localhost kernel: device-mapper: table: 253:0: adding target device sdc caused an alignment inconsistency: physical_block_size=4096, logical_block_size=512, alignment_offset=170496, start=0 Jul 23 15:14:58 localhost kernel: device-mapper: table: 253:1: adding target device sdd caused an alignment inconsistency: physical_block_size=262144, logical_block_size=512, alignment_offset=16384, start=0 Jul 23 15:14:58 localhost kernel: device-mapper: table: 253:1: adding target device sdd caused an alignment inconsistency: physical_block_size=262144, logical_block_size=512, alignment_offset=16384, start=0 Jul 23 15:15:58 localhost vdsm scanDomains WARNING Metadata collection for domain path /rhev/data-center/mnt/rhevm:_opt_exports_export timedout#012Traceback (most recent call last):#012 File "/usr/share/vdsm/storage/fileSD.py", line 662, in collectMetaFiles#012 sd.DOMAIN_META_DATA))#012 File "/usr/share/vdsm/storage/remoteFileHandler.py", line 297, in callCrabRPCFunction#012*args, **kwargs)#012 File "/usr/share/vdsm/storage/remoteFileHandler.py", line 184, in callCrabRPCFunction#012rawLength = self._recvAll(LENGTH_STRUCT_LENGTH, timeout)#012 File "/usr/share/vdsm/storage/remoteFileHandler.py", line 150, in _recvAll#012raise Timeout()#012Timeout Jul 23 15:16:00 localhost vdsm scanDomains WARNING Metadata collection for domain path /rhev/data-center/mnt/rhevm:_opt_exports_export timedout#012Traceback (most recent call last):#012 File "/usr/share/vdsm/storage/fileSD.py", line 662, in collectMetaFiles#012 sd.DOMAIN_META_DATA))#012 File "/usr/share/vdsm/storage/remoteFileHandler.py", line 297, in callCrabRPCFunction#012*args, **kwargs)#012 File "/usr/share/vdsm/storage/remoteFileHandler.py", line 184, in callCrabRPCFunction#012rawLength = self._recvAll(LENGTH_STRUCT_LENGTH, timeout)#012 File "/usr/share/vdsm/storage/remoteFileHandler.py", line 150, in _recvAll#012raise Timeout()#012Timeout Jul 23 15:16:09 localhost vdsm scanDomains WARNING Metadata collection for domain path /rhev/data-center/mnt/rhevm:_opt_exports_export timedout#012Traceback (most recent call last):#012 File "/usr/share/vdsm/storage/fileSD.py", line 662, in collectMetaFiles#012 sd.DOMAIN_META_DATA))#012 File "/usr/share/vdsm/storage/remoteFileHandler.py", line 297, in callCrabRPCFunction#012*args, **kwargs)#012 File "/usr/share/vdsm/storage/remoteFileHandler.py", line 184, in callCrabRPCFunction#012rawLength = self._recvAll(LENGTH_STRUCT_LENGTH, timeout)#012 File "/usr/share/vdsm/storage/remoteFileHandler.py", line 150, in _recvAll#012raise Timeout()#012Timeout Has anyone met such a problem ?
