Wrong network threshold limit warnings on 4.2.5
by Florian Schmid 04 Sep '18

04 Sep '18

Good morning, since we have upgraded to version 4.2.5, we get a lot of warnings about network interface exceeded defined threshold limits. For example: Aug 31, 2018, 7:54:05 AM Host xxx has network interface which exceeded the defined threshold [95%] (enp9s0.80: transmit rate[100%], receive rate [12%]) This is a 10 Gbit interface and on our monitoring software, which is getting network statistics every 10s, the bandwidth of TX was 150 Mbit maximum at this time, so far away from being 100%. Could it be, that the engine detected the wrong interface speed or there is a calculation error? In the engine for this host, I have 10000 Mbps for all interfaces. I have checked now all those warnings on our different hosts and they happen every time, we go over 100 Mbit and this is for sure quite often... Can I maybe disable these warnings, because we have it anyway in our monitoring software? If you need any logs, please ask. BR Florian Schmid

Bricks do not appear in oVirt Manager UI under Hosts unless manually created on nodes.

I have a CentOS 7.5 system running the oVirt-Engine package as the manager for three oVirt Nodes (version 4.2). Two of the nodes have a 200GB disk and one has a 2GB disk. I am attempting to create a Gluster Volume that replicates between the two 200GB disks with the 2GB as Arbiter. When I create the bricks by going to Hosts > host1 > Storage Devices > Create Brick (with the 200GB device selected), it succeeds, but no bricks appear under the Bricks tab for the Host. Doing the same for host2 and host3 results in the same problem. If I run the following command on a host `gluster volume create test-volume replica 3 arbiter 1 192.168.5.{50,60,40}:/gluster-bricks/200GBbrick/test`, it creates the volume correctly and the bricks then appear as they should. However, then these Bricks are labeled as "Down" and when I go to Storage > Volumes, I get this error: ``` Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : Cannot read property 'a' of null Please have your administrator check the UI logs ``` The Volume is also shown as "Down". SELinux is enabled on my CentOS 7.5 system. I'm not really sure what the correct method is to create bricks then a Volume in Gluster through the oVirt Management UI, but I've followed the guides and this is where it has got me.

oVirt Node 4.2.3.1. to 4.2.5 upgrade trouble, log attached
by Matt Simonsen 03 Sep '18

03 Sep '18

Hello all, I've emailed about similar trouble with an oVirt Node upgrade using the ISO install. I've attached the /tmp/imgbased.log file in hopes it will help give a clue as to why the trouble. Since these use NFS storage I can rebuild, but would like to know, ideally, what caused the upgrade to break. Truthfully following the install, I don't think I have done *that* much to these systems, so I'm not sure what would have caused the problem. I have done several successful upgrades in the past and most of my standalone systems have been working great. I've been really happy with oVirt, so kudos to the team. Thanks for any help, Matt

Gluster clients intermittently hang until first gluster server in a Replica 1 Arbiter 1 cluster is rebooted, server error: 0-management: Unlocking failed & client error: bailing out frame type(GlusterFS 4.x v1) op(INODELK(29)) xid = 0x2131 sent = <datestamp>. timeout = 1800

We've got an odd problem where clients are blocked from writing to Gluster volumes until the first node of the Gluster cluster is rebooted. I suspect I've either configured something incorrectly with the arbiter / replica configuration of the volumes, or there is some sort of bug in the gluster client-server connection that we're triggering. I was wondering if anyone has seen this or could point me in the right direction? Environment: Typology: 3 node cluster, replica 2, arbiter 1 (third node is metadata only). Version: Client and Servers both running 4.1.3, both on CentOS 7, kernel 4.18.x, (Xen) VMs with relatively fast networked SSD storage backing them, XFS. Client: Native Gluster FUSE client mounting via the kubernetes provider Problem: Seemingly randomly some clients will be blocked / are unable to write to what should be a highly available gluster volume. The client gluster logs show it failing to do new file operations across various volumes and all three nodes of the gluster. The server gluster (or OS) logs do not show any warnings or errors. The client recovers and is able to write to volumes again after the first node of the gluster cluster is rebooted. Until the first node of the gluster cluster is rebooted, the client fails to write to the volume that is (or should be) available on the second node (a replica) and third node (an arbiter only node). What 'fixes' the issue: Although the clients (kubernetes hosts) connect to all 3 nodes of the Gluster cluster - restarting the first gluster node always unblocks the IO and allows the client to continue writing. Stopping and starting the glusterd service on the gluster server is not enough to fix the issue, nor is restarting its networking. This suggests to me that the volume is unavailable for writing for some reason and restarting the first node in the cluster either clears some sort of TCP sessions between the client-server or between the server-server replication. Expected behaviour: If the first gluster node / server had failed or was blocked from performing operations for some reason (which it doesn't seem it is), I'd expect the clients to access data from the second gluster node and write metadata to the third gluster node as well as it's an arbiter / metadata only node. If for some reason the a gluster node was not able to serve connections to clients, I'd expect to see errors in the volume, glusterd or brick log files (there are none on the first gluster node). If the first gluster node was for some reason blocking IO on a volume, I'd expect that node either to show as unhealthy or unavailable in the gluster peer status or gluster volume status. Client gluster errors: staging_static in this example is a volume name. You can see the client trying to connect to the second and third nodes of the gluster cluster and failing (unsure as to why?) The server side logs on the first gluster node do not show any errors or problems, but the second / third node show errors in the glusterd.log when trying to 'unlock' the 0-management volume on the first node. On a gluster client (a kubernetes host using the kubernetes connector which uses the native fuse client) when its blocked from writing but the gluster appears healthy (other than the errors mentioned later): [2018-09-02 15:33:22.750874] E [rpc-clnt.c:184:call_bail] 0-staging_static-client-2: bailing out frame type(GlusterFS 4.x v1) op(INODELK(29)) xid = 0x1cce sent = 2018-09-02 15:03:22.417773.

Possible vdsmd issues - " WARN Worker blocked"
by Johnson, Tim 31 Aug '18

31 Aug '18

Hi all, We have had a bit of a strange issue with the starting of the self-hosted engine due to the vdsm and ovirt-ha processes having errors and not able to be started. Running Ovirt version 4.2 with Gluster mounts (not hyper converged) gluster 3.12.13 replicated volumes with arbiter brick. The mounts for the storage are mounted on all the Ovirt hosts and able to read/touch files on the mounts. Unfortunately we can not pin a specific timeframe when this started happening. Meaning we don’t know if it started after a specific update or any other event. The vdsmd is throwing errors (bottom – with version numbers) when trying to check the status of the self -hosted engine getting : # hosted-engine --vm-status The hosted engine configuration has not been retrieved from shared storage. Please ensure that ovirt-ha-agent is running and the storage server is reachable. Thanks for any assistance. systemctl status ovirt-ha-agent -l ● ovirt-ha-agent.service - oVirt Hosted Engine High Availability Monitoring Agent Loaded: loaded (/usr/lib/systemd/system/ovirt-ha-agent.service; enabled; vendor preset: disabled) Active: activating (auto-restart) (Result: exit-code) since Thu 2018-08-30 13:24:40 CDT; 2s ago Process: 17135 ExecStart=/usr/share/ovirt-hosted-engine-ha/ovirt-ha-agent (code=exited, status=157) Main PID: 17135 (code=exited, status=157) systemctl status ovirt-ha-broker -l ● ovirt-ha-broker.service - oVirt Hosted Engine High Availability Communications Broker Loaded: loaded (/usr/lib/systemd/system/ovirt-ha-broker.service; enabled; vendor preset: disabled) Active: active (running) since Thu 2018-08-30 13:10:35 CDT; 14min ago Main PID: 14863 (ovirt-ha-broker) Tasks: 4 CGroup: /system.slice/ovirt-ha-broker.service └─14863 /usr/bin/python /usr/share/ovirt-hosted-engine-ha/ovirt-ha-broker Aug 30 13:10:35 rrb-vmhost1.rrc.local systemd[1]: Started oVirt Hosted Engine High Availability Communications Broker.

Can anyone tell me if this can be done? I have read various articles and I'm not sure. http://blog.domb.net/?p=2141 https://www.ovirt.org/develop/release-management/features/integration/allin…<http://blog.domb.net/?p=2141> According to my google search results the ovirt article date is within the last year approximately but I says deprecated after version 3.6 yet the 1st article makes it seem it can be done. I know this goes against standard practice but there is a reason I'm trying to do it. If it is possible, can anyone point me to a guide or give me an overview of the steps needed? Thank you for your help!
