Engine status : unknown stale-data on single node
by Wood, Randall 01 Apr '20

01 Apr '20

I have a three node Ovirt cluster where one node has stale-data for the hosted engine, but the other two nodes do not: Output of `hosted-engine --vm-status` on a good node: ``` !! Cluster is in GLOBAL MAINTENANCE mode !! --== Host ovirt2.low.mdds.tcs-sec.com (id: 1) status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : ovirt2.low.mdds.tcs-sec.com Host ID : 1 Engine status : {"health": "good", "vm": "up", "detail": "Up"} Score : 3400 stopped : False Local maintenance : False crc32 : f91f57e4 local_conf_timestamp : 9915242 Host timestamp : 9915241 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=9915241 (Fri Mar 27 14:38:14 2020) host-id=1 score=3400 vm_conf_refresh_time=9915242 (Fri Mar 27 14:38:14 2020) conf_on_shared_storage=True maintenance=False state=GlobalMaintenance stopped=False --== Host ovirt1.low.mdds.tcs-sec.com (id: 2) status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : ovirt1.low.mdds.tcs-sec.com Host ID : 2 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} Score : 3400 stopped : False Local maintenance : False crc32 : 48f9c0fc local_conf_timestamp : 9218845 Host timestamp : 9218845 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=9218845 (Fri Mar 27 14:38:22 2020) host-id=2 score=3400 vm_conf_refresh_time=9218845 (Fri Mar 27 14:38:22 2020) conf_on_shared_storage=True maintenance=False state=GlobalMaintenance stopped=False --== Host ovirt3.low.mdds.tcs-sec.com (id: 3) status ==-- conf_on_shared_storage : True Status up-to-date : False Hostname : ovirt3.low.mdds.tcs-sec.com Host ID : 3 Engine status : unknown stale-data Score : 3400 stopped : False Local maintenance : False crc32 : 620c8566 local_conf_timestamp : 1208310 Host timestamp : 1208310 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=1208310 (Mon Dec 16 21:14:24 2019) host-id=3 score=3400 vm_conf_refresh_time=1208310 (Mon Dec 16 21:14:24 2019) conf_on_shared_storage=True maintenance=False state=GlobalMaintenance stopped=False !!

Since it seems the agent depends on the broker, the broker logs includes this snippet, repeating roughly every 3 seconds: ``` MainThread::INFO::2020-03-27 15:01:06,584::broker::47::ovirt_hosted_engine_ha.broker.broker.Broker::(run) ovirt-hosted-engine-ha broker 2.3.6 started MainThread::INFO::2020-03-27 15:01:06,584::monitor::40::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Searching for submonitors in /usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/broker/submonitors MainThread::INFO::2020-03-27 15:01:06,585::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor engine-health MainThread::INFO::2020-03-27 15:01:06,585::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor storage-domain MainThread::INFO::2020-03-27 15:01:06,585::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor network MainThread::INFO::2020-03-27 15:01:06,587::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor cpu-load-no-engine MainThread::INFO::2020-03-27 15:01:06,587::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor mem-free MainThread::INFO::2020-03-27 15:01:06,587::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor network MainThread::INFO::2020-03-27 15:01:06,588::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor mgmt-bridge MainThread::INFO::2020-03-27 15:01:06,588::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor storage-domain MainThread::INFO::2020-03-27 15:01:06,589::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor cpu-load-no-engine MainThread::INFO::2020-03-27 15:01:06,589::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor engine-health MainThread::INFO::2020-03-27 15:01:06,589::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor mgmt-bridge MainThread::INFO::2020-03-27 15:01:06,589::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor cpu-load MainThread::INFO::2020-03-27 15:01:06,590::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor cpu-load MainThread::INFO::2020-03-27 15:01:06,590::monitor::49::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Loaded submonitor mem-free MainThread::INFO::2020-03-27 15:01:06,590::monitor::50::ovirt_hosted_engine_ha.broker.monitor.Monitor::(_discover_submonitors) Finished loading submonitors MainThread::INFO::2020-03-27 15:01:06,678::storage_backends::373::ovirt_hosted_engine_ha.lib.storage_backends::(connect) Connecting the storage MainThread::INFO::2020-03-27 15:01:06,678::storage_server::349::ovirt_hosted_engine_ha.lib.storage_server.StorageServer::(connect_storage_server) Connecting storage server MainThread::INFO::2020-03-27 15:01:06,717::storage_server::356::ovirt_hosted_engine_ha.lib.storage_server.StorageServer::(connect_storage_server) Connecting storage server MainThread::INFO::2020-03-27 15:01:06,732::storage_server::413::ovirt_hosted_engine_ha.lib.storage_server.StorageServer::(connect_storage_server) Refreshing the storage domain MainThread::WARNING::2020-03-27 15:01:08,940::storage_broker::97::ovirt_hosted_engine_ha.broker.storage_broker.StorageBroker::(__init__) Can't connect vdsm storage: [Errno 5] Input/output error: '/rhev/data-center/mnt/glusterSD/ovirt2:_engine/182a4a94-743f-4941-89c1-dc2008ae1cf5/ha_agent/hosted-engine.lockspace' ``` I restarted the stale node yesterday, but it still shows stale data from December of last year. What is the recommended way for me to try to recover from this? (This came to my attention when warnings concerning space on the /var/log partition began popping up.) Thank you, Randall

Hi to all. I'm trying to connect two vm, on the same "local storage" host, with an internal isolated network. My setup; VM A: * eth0 with an external ip * eth1, with 1922.168.1.1/24 VM B * eth0 with an external ip * eth1, with 1922.168.1.2/24 the eth1 interfaces are connetter by a network created on external provider ovirt-network-ovn , whithout a subnet defined. Now, the external ip works fine, but the two vm cannot connect through the local network ping: ko arping: ko any idea to what to check?

ovirt-guest-agent for CentOS 8
by Eduardo Mayoral 30 Mar '20

30 Mar '20

Hi, Just like many of you I am testing my first CentOS 8 VMs on top of ovirt. I am not finding the package ovirt-guest-agent.noarch . Closest I can find is qemu-guest-agent.x86_64 After installing and starting it, I do see information reported on the "Guest info" tab. Can anybody confirm if this is indeed the agent we should be using? Is there - or will there be - a more specific package for ovirt guests? Thanks! -- Eduardo Mayoral Jimeno Systems engineer, platform department. Arsys Internet. emayoral(a)arsys.es - +34 941 620 105 - ext 2153

Hello! Tell me, can I install oVirt on Fedora 31? I try to install "http://resources.ovirt.org/pub/yum-repo/ovirt-release42.rpm" but only "ovirt-4.2.repo" appears in "yum.repos.d". "ovirt-4.2-dependencies.repo" is missing. ok, I installed ovirt-release42.rpm on a virtual machine with centos7 and downloaded both files from it. but when I try to run "yum install ovirt-hosted-engine-setup" I get "Error: Failed to download metadata for repo 'ovirt-4.2': Cannot prepare internal mirrorlist: No URLs in mirrorlist" and "No match for argument: ovirt -hosted-engine-setup " sorry for my english, this is a translator :)

Debian guest Agent
by eevans＠digitaldatatechs.com 30 Mar '20

30 Mar '20

I am revisiting this as I have had no luck getting it resolved. I have 2 Debian servers, one is an email appliance and one is a virtual pbx. The guest agent works in the email appliance after following an article to get the agent to work properly, but the agent in the pbx has never worked. I have an exclamation point saying the guest agent needs to be installed. It is installed and running. I'm not sure why the agent is not checking in but any help would be appreciated. Thanks.
