no space left to upgrade hosted-engine
by Nathanaël Blanchet 04 Oct '18

04 Oct '18

I've deployed and hosted-engine with the hosted-engine provided appliance. When runing hosted-engine --upgrade-appliance on one host, it tells me "If your engine VM is already based on el7 you can also simply upgrade the engine there." So I launched a yum update on the hosted-engine, but it complains there is no space left on / [root@infra ~]# df -h Sys. de fichiers Taille Utilisé Dispo Uti% Monté sur /dev/vda3 6,2G 6,2G 20K 100% / devtmpfs 7,8G 0 7,8G 0% /dev tmpfs 7,8G 4,0K 7,8G 1% /dev/shm tmpfs 7,8G 9,0M 7,8G 1% /run tmpfs 7,8G 0 7,8G 0% /sys/fs/cgroup /dev/mapper/ovirt-home 1014M 33M 982M 4% /home /dev/mapper/ovirt-tmp 2,0G 33M 2,0G 2% /tmp /dev/vda1 1014M 162M 853M 16% /boot /dev/mapper/ovirt-var 20G 631M 20G 4% /var /dev/mapper/ovirt-log 10G 58M 10G 1% /var/log /dev/mapper/ovirt-audit 1014M 59M 956M 6% /var/log/audit tmpfs 1,6G 0 1,6G 0% /run/user/0 Is the only way is to deploy the new appliance? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 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 blanchet(a)abes.fr

ODL and Openstack issue
by Soujanya Bargavi 04 Oct '18

04 Oct '18

I am running one controller and one compute node. Controller node is running both ODL and OpenStack. I created tenants, underthem i created networks and launched instances on them. All is see on ODL web GUI is 3 swithces, and I guess those are br-int and br-ex of controller and br-int of compute and the links are missing too. Is there anyway where I can see my whole OpenStack https://goo.gl/6CgufL topology on ODL GUI with the links?

lost connection to hosted engine
by Artem Tambovskiy 04 Oct '18

04 Oct '18

Hi, Just run into the issue during cluster upgrade from 4.24 to 4.2.6.1. I'm running small cluster with 2 hosts and gluster storage. Once I upgraded one of the hosts to 4.2.6.1 something went wrong (looks like it tried to start HE instance) and I can't connect to hosted-engine any longer. As I can see HostedEngine is still running on the second host (and another yet 7 VM's) , but I can't stop it. ovirt-ha-agent and ovirt-ha-broker are failing to start. hosted-engine --vm-status gives nothing but error message "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." ps -ef shows plenty of vdsm processes in defunc state thats probably the reason why agent and brocker can't start. Just wondering that is the good way to start problem resolution here to minimize downtime for running VM's? Restart vdsm and try again restarting agent and broker or just reboot the whole host? Regards, Artem

ISCSI domain won't attach
by Vincent Royer 03 Oct '18

03 Oct '18

I setup an iscsi domain in hopes of moving away from NFS. I created a new logical network for this on a storage vlan. both hosts and storage server grabbed a good IP on this vlan. ISCSI Domain connected ok and I started moving disks over from the NFS domain. Transfers were completing so I let it do its thing. This morning, after the transfers completed, three things occurred in quick succession: 1. Affinity Rules Enforcement Manager started. 2. Invalid status on Data Center. Setting status to Non Responsive. 3. Storage Pool Manager runs on Host brian.xxx.net (Address: brian.xxx.net) Data Center. 4. Storage Domain domiscsi was deactivated by system because it's not visible by any of the hosts. Try to attach it again and it fails. Have another coffee and try to attach again to get logs, and this time it attaches just fine. domain disconnected vdsm log: https://pastebin.com/pfGerEE5 Successful attach operation vdsm log: https://pastebin.com/c0U07QXg host Brian can't seem to keep the storage domain https://pastebin.com/ySAqiqA3 both hosts seem to have connected sessions when looking from the storage server: [image: image.png] Seems like it might be one problematic host, because engine keeps trying to reboot it to get it to reconnect to the storage domain. Maybe after a few tries it just deems the domain is bad. Not sure! Any help is appreciated!

clean up a fc lun to reuse it
by Nathanaël Blanchet 03 Oct '18

03 Oct '18

Hi all, I tried to install the Hosted-Engine on a FC lun, and the first time, it failed at the end because of a sanlock issue. So I fixed it and the re-deoployed from scratch until this new issue [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Physical device initialization failed. Please check that the device is empty and accessible by the host.]". HTTP response code is 400. Before, I found that the lun [2] was used: [ INFO ] ok: [localhost] The following luns have been found on the requested target: [1] 36006016039a142001792ac5b1b9e513a 1024GiB DGC VRAID status: free, paths: 8 active [2] 36006016039a142006755b25b7505d26b 100GiB DGC VRAID status: used, paths: 8 active So it was the good explanation for the failure. Following the admin guide, I cleaned up the lun using |# dd if=/dev/zero of=/dev/mapper/||36006016039a142006755b25b7505d26b bs=1M count=200 oflag=direct| And re-deployed it until it complains the device was not empty despite of before. The script still reported that the status of the lun was "used" Finally, I rebooted the host, and that time the script considered the lun status as free. So there is somewhere a bit of code into the ansible script that keeps the old status of the lun before dd, until rebooting. Is there an other way to refresh the lun status after dd ?
