Timestamp offset in engine.log
by Ian Fraser 09 Mar '19

09 Mar '19

Hello, I am trying to follow the instructions for installing the metrics store and a prerequisite is ensuring the timestamps in /var/log/ovirt- engine/engine.log include a UTC offset (at bottom of this page: https://www.ovirt.org/documentation/metrics-install-guide/Introduction.html ). Mine currently do not (i.e. they look like "2019-03-07 14:14:23,223Z"). "timedatectl | grep -i 'time zone'" shows "Time zone: Europe/London (GMT, +0000)" Can anyone please tell me how to change this timestamp format to statisfy this prerequisite?

You can change the MTU in the network config in oVirt engine. The management portal. Go to clusters then networks or something like that. You can then modify the MTU. MTU can also be set manually in network scripts on the host but you need to define this in the engine. At least this is how I got Infiniband working. I can send screenshots on Monday.

Install OS, Install OFED, Create Bond for ib0 and ib1 - bond0 Set IP to bond0, and MTU to 65520. Add Host to oVirt Cluster At this moment of time everything is Fine. Next step. Assign New network to bond0, oVirt set MTU to 1500, and ... That is all. No storage, No IP. I can't change MTU to 2044 or 65520 and can't assign IP to IB interface. From system perspective i do understand why. oVirt Creates new bridge using brctl - and brctl didn't support IPoIB, but how can i change it back to original config? _______________________________________________ Users mailing list -- users(a)ovirt.org<mailto:users@ovirt.org> To unsubscribe send an email to users-leave(a)ovirt.org<mailto:users-leave@ovirt.org> Privacy Statement: https://urldefense.proofpoint.com/v2/url?u=https-3A__www.ovirt.org_site_pri… oVirt Code of Conduct: https://urldefense.proofpoint.com/v2/url?u=https-3A__www.ovirt.org_communit… List Archives: https://urldefense.proofpoint.com/v2/url?u=https-3A__lists.ovirt.org_archiv…

oVirt 4.3 and AMD Opteron G3 CPU
by Jiří Sléžka 08 Mar '19

08 Mar '19

Hi, I know, old AMD Opterons G3 are unsupported in oVirt 4.3 but anyway, is there a way to switch cluster to 4.3 mode with these old CPUs? On the other hand 4.2 mode is no problem, I just would like to test new stuff (on legacy hw ;-) Cheers, Jiri Slezka

Re: oVirt Performance (Horrific)
by Strahil 08 Mar '19

Hi Drew, During my tests on gluster v3, using 'disable.nfs: false' and using that as ovirt storage brought maximum performance for my 1 Gbit/s network. Can you try using NFS and if it works well, you can disable nfs and get NFS Ganesha up and running. It seems that FUSE in gluster v5 is performing way better, but still it is not the optimal solution. Best Regards, Strahil Nikolov

Re: error failed to execute stage 'misc configuration': failed to start service 'openvswitch'
by Strahil 08 Mar '19

This should work only for EL7 based systems. Find what provides it: yum whatprovides '*/openvswitch.service' Then check if it is installed: rpm -qa <replace with output of previous command> If not, install via 'yum install <replace with output of previous command>' Best Regards, Strahil Nikolov

LUN ID Change on Storage Domain
by Alan G 08 Mar '19

08 Mar '19

Hi, I made an error when provisioning a new FC storage domain and gave it LUN ID 0 by mistake. I now need to move it to another ID. Can I do this: - 1. Shutdown all VMs on the domain. 2. Put the domain in maintenance. 3. Change the LUN ID. 4. Force SCSI rescan on every host. 5. Bring the domain out of maintenance. Will oVIrt still recognise the domain on a different LUN ID? Thanks, Alan

When you create the new network, can't you set the MTU also? I know that UI allows changing MTU, but never checked if it can be set during definition. Best Regards, Strahil Nikolov
