[ovirt-users] Re: oVirt 4.2.5.1-1.el7 JSON-RPC statistics error

I think the upgrade may not have affected the mom package, because no new mom rpm version was released for a few months. I'm not sure why the import fails even if the file is there. As a workaround, mom can be configured to use the older (deprecated) json rpc interface to communicate with vdsm. T

I upgraded my test cluster to 4.2.5.2-1 last night (hosts rebooted after update) and I've started to see the error again. As before it seems to be limited to the one host, I've checked that /usr/lib/python2.7/site-packages/mom/HypervisorInterfaces/vdsmjsonrpcclientInterface.py exists, which it

Yes, copying it from another host with mom version 0.5.12 is enough. I'm not sure why it was not installed. The file is in the rpm. On Wed, 18 Jul 2018 at 16:38, Maton, Brett wrote: > Bingo > > How could that file not be installed/deployed ? > > > Should I simply copy it from one of the other h

Bingo How could that file not be installed/deployed ? Should I simply copy it from one of the other hosts to make the message go away ? On 18 July 2018 at 15:30, Andrej Krejcir wrote: > Maybe the python module is missing. Can you check if this file exists? > > /usr/lib/python2.7/site-packages

Maybe the python module is missing. Can you check if this file exists? /usr/lib/python2.7/site-packages/mom/HypervisorInterfaces/vdsmjsonrpcclientInterface.py Andrej On Wed, 18 Jul 2018 at 16:04, Maton, Brett wrote: > I just checked the mom version, it's already at 0.5.12 > > # rpm -qa mom >

I just checked the mom version, it's already at 0.5.12 # rpm -qa mom mom-0.5.12-1.el7.centos.noarch All the physical hosts are fully updated /patched. Regards, Brett On 18 July 2018 at 14:08, Andrej Krejcir wrote: > Hi, > > Looking at MOM logs, the problem seems to be that MOM is configured t

[ovirt-users] Re: oVirt 4.2.5.1-1.el7 JSON-RPC statistics error

Hi, Looking at MOM logs, the problem seems to be that MOM is configured to use 'vdsmjsonrpcclient' module to communicate with vdsm, but it cannot find this module, probably because it is an older version. Updating MOM to version 0.5.12 should fix it. Regards, Andrej On Wed, 18 Jul 2018 at 14:4
