relationship between sanlock and wdmd services
by Gianluca Cecchi 05 Jul '16

05 Jul '16

Hello, sometimes one could be in need to keep hypervisor up (CentOS 7.2 in my case) but with all ovirt releated services stopped. I see that sanlock and wdmd systemd units are bot part of sanlock rpm package. In these cases, having only one single host in a lab environment, I follow this comment by Joop http://lists.ovirt.org/pipermail/users/2016-June/040214.html So, I stop all a VMs, put env in global maintenance and then on host: systemctl stop ovirt-ha-agent systemctl stop ovirt-ha-broker shutdown engine vm On host again: systemctl stop vdsmd systemctl stop sanlock.service At this point sometimes I can work, sometimes after some minutes the host restarts itself, I presume due to wdmd In fact I see in messages: Jul 4 17:05:47 ractor wdmd[1258]: test failed rem 26 now 804 ping 760 close 770 renewal 697 expire 777 client 1285 sanlock_2025c2ea-6205-4bc1-b29d-745b47f8f806:1 Jul 4 17:05:48 ractor wdmd[1258]: test failed rem 25 now 805 ping 760 close 770 renewal 697 expire 777 client 1285 sanlock_2025c2ea-6205-4bc1-b29d-745b47f8f806:1 Jul 4 17:05:49 ractor wdmd[1258]: test failed rem 24 now 806 ping 760 close 770 renewal 697 expire 777 client 1285 sanlock_2025c2ea-6205-4bc1-b29d-745b47f8f806:1 Jul 4 17:05:50 ractor wdmd[1258]: test failed rem 23 now 807 ping 760 close 770 renewal 697 expire 777 client 1285 sanlock_2025c2ea-6205-4bc1-b29d-745b47f8f806:1 Jul 4 17:05:51 ractor wdmd[1258]: test failed rem 22 now 808 ping 760 close 770 renewal 697 expire 777 client 1285 sanlock_2025c2ea-6205-4bc1-b29d-745b47f8f806:1 Jul 4 17:05:51 ractor systemd[1]: wdmd.service stop-sigterm timed out. Killing. Jul 4 17:05:51 ractor systemd[1]: wdmd.service: main process exited, code=killed, status=9/KILL Jul 4 17:05:51 ractor systemd[1]: Stopped Watchdog Multiplexing Daemon. Jul 4 17:05:51 ractor systemd[1]: Unit wdmd.service entered failed state. Jul 4 17:05:51 ractor systemd[1]: wdmd.service failed. In systemd unit file for sanlock: [Unit] Description=Shared Storage Lease Manager After=syslog.target Wants=wdmd.service Nothing special instead for wdmd. I tried also to stop it but server still rebooted. Also, it seems to me that sometimes sanlock is ale to stop, someties exits with "failed". So the question is if wdmd is able to be stopped or if it is the same behavior of old watchdogd on Linux Thanks in advance, Gianluca

Cannot add Hosted Engine Host because of missing answersfile
by Matt . 05 Jul '16

05 Jul '16

Hi! Apperently there has been something gone wrong with the hosted engine install which I can perfectly start but cannot add any Host to the HA setup. I'm missing an answers.conf on my host where I did the installation. Has anyone an idea if I can fix this without a new full deploy ? I'm on 3.6.7 Some errorlog: --== STORAGE CONFIGURATION ==-- During customization use CTRL-D to abort. Please specify the storage you would like to use (glusterfs, iscsi, fc, nfs3, nfs4)[nfs3]: Please specify the full shared storage connection path to use (example: host:/path): filer-01.my-domain.tld:/vol/vol0/oVIRT_HE The specified storage location already contains a data domain. Is this an additional host setup (Yes, No)[Yes]? [ INFO ] Installing on additional host Please specify the Host ID [Must be integer, default: 2]: --== SYSTEM CONFIGURATION ==-- [WARNING] A configuration file must be supplied to deploy Hosted Engine on an additional host.

Re: [ovirt-users] [oVirt 4.0] Is it possible to access oVirt through a reverse proxy
by Martin Perina 05 Jul '16

05 Jul '16

Hi, In 4.0 you can access oVirt engine only with the same FQDN that was specified during engine-setup. If you have used different FQDN, you may change it using ovirt-engine-rename tool.

Ovirt Node NG 4.0.0 wants to bridge my infiniband link
by Giorgio Biacchi 04 Jul '16

04 Jul '16

Hi list, I'm trying a test installation of the new Ovirt Node Image and engine before upgrading my 3.6 installation. In my current environment every hypervisor access the NFS shared data domain via infiniband. With a couple of vdsm hooks I was able to set the infiniband link in connected mode and set a MTU of 65520. In my case the infiniband link is used as a common NIC, I don't use RDMA, only IP over infiniband to access the data domain. Now, when I attempt to setup host networking, the system try to bridge the connection "ibstorage" (defined in networks tab) with ib0 device. But a non ethernet device cannot be bridged that way and host networking setup fails. Any idea or suggestion? With 3.6 (node and engine) all was fine.

Unable to set up oVirt 4.0 HE using glusterfs storage
by Kevin Hung 04 Jul '16

04 Jul '16

Hello, I thought I would ask the list if anyone is aware of this issue (or if I am doing something obviously wrong) before I submit a bug report. It looks like I am not able to choose glusterfs as a storage option for deploying a Hosted Engine in oVirt 4.0 Node Next. I believe it is failing to execute the following command: /sbin/gluster --mode=script --xml volume info mgmttank --remote-host=storage1.nullaxiom.com When I run the command manually, I get a blank line as output and checking in /var/log/glusterfs/cli.log, it seems to be exiting with error code -2. I have tried disabling the firewall on both host and gluster server, but it did not make a difference. I am able to manually mount the gluster volume on the host, and I had a working oVirt 3.6 installation using the same exact gluster server. Console output below: [ INFO ] Stage: Initializing [ INFO ] Generating a temporary VNC password. [ INFO ] Stage: Environment setup During customization use CTRL-D to abort. Continuing will configure this host for serving as hypervisor and create a VM where you have to install the engine afterwards. Are you sure you want to continue? (Yes, No)[Yes]: It has been detected that this program is executed through an SSH connection without using screen. Continuing with the installation may lead to broken installation if the network connection fails. It is highly recommended to abort the installation and run it inside a screen session using command "screen". Do you want to continue anyway?

Hi, today I will migrate my backup tool [1] from oVirt version 3 to 4. Is there anywhere a documentation to the new SDK? I downloaded the source and read in the meantime through the code. It seems it will be a lot of work :-( cheers gregor [1] https://github.com/wefixit-AT/oVirtBackup

by Tadas 04 Jul '16

04 Jul '16

is there any documentation o oVirt guest agent commands? To be more precise: i need to pass commands to oVirt guest agent from hypervisor. Reading info works fine: socat /var/lib/libvirt/qemu/channel/target/domain-20- win7_32bit/com.redhat.serial.0 - {"applications": ["Python 2.7.12rc1", "SPICE Guest Tools", "Total Commander (Remove or Repair)", "Python 2.7 pywin32-216", "Microsoft .NET Framework 4.6.1", "Git version 2.9.0", "WinRAR 5.40 beta 2 (32- bit)", "Notepad++"], "__name__": "applications"} {"__name__": "host-name", "name": "WIN7_32BIT"} {"__name__": "os-version", "version": "Win 7"} I'm unable to find how to send command (lets say "shutdown") to agent?. echo "shutdown" | socat /var/lib/libvirt/qemu/channel/target/domain-20- win7_32bit/com.redhat.kvm-vdi.0 - Does not seem to work Thank you for your help.

Re: [ovirt-users] Change admin password: new password already used
by Martin Perina 03 Jul '16

03 Jul '16

Hi, Please take a look https://www.ovirt.org/develop/release-management/features/infra/aaa-jdbc/ where you can find more info about ovirt-aaa-jdbc-tool. By default we remember several previous passwords and check for them during password change. You can change that policy using 'ovirt-aaa-jdbc-tool settings' or you can use --force option during password change.
