[ovirt-users] Re: GlusterFS Monitoring/Alerting

[marcel d'heureuse]

Please be carefull. We have used a prometheus plug in and it has requested 
every minute the gluster status. And we habe 50 vm running over three servers. 
In case that the system is on load the answer require more than one minute.

After three weeks the glusterfs was overloaded and all vms was quite slow. 

Try to reduce your request in an half hour base procedure if you want to see 
all relevant  data.

[ovirt-users] Re: Time Drift Issues

[Marcos Sungaila]

Hi Nur,

ntpd has a 300sec limit for synchronization. If you want a more flexible NTP 
client, use chronyd.
If you prefer to use ntpd, you should have ntpdate as a boot client and ntpd as 
a runtime client.
When the server boots, the ntpdate client will sync time no matter the 
difference. As a boot client, it runs only once and exits. Then the ntpd 
service starts, and keep your server clock in sync with an external source.
On distributions like CentOS and similar, ntpdate reads the external time 
sources configuration from ntpd.conf. You should need booth packages and 
services installed and enabled:
I prefer chronyd since it does not need any extra service or procedure to keep 
clock synchronization.

Regards,
Marcos

Subject: [External] : [ovirt-users] Time Drift Issues

Hi All,

Recently I got an warning in our cluster about time drift :
Host x has time-drift of 672 seconds while maximum configured value is 300 
seconds.

What should I do to address this issue ? Should I reconfigure / configure ntp 
client on all host ?

Thanks before.

Nur Imam Febrianto

[ovirt-users] mom-vdsm doesn't restart after upgrade

[Nathanaël Blanchet]

Hello,

I performed a host upgrade from 4.4.5  to 4.4.8, and vdsmd failed to 
launch with this log:


Sep 07 16:16:52 kamen systemd[1]: mom-vdsm.service: Job 
mom-vdsm.service/start failed with result 'dependency'.
Sep 07 16:16:54 kamen systemd[1]: Dependency failed for MOM instance 
configured for VDSM purposes.


Following this ticket 
https://bugzilla.redhat.com/show_bug.cgi?id=1557735, I managed to launch 
mom-vdsm and so vdsmd doing:


vdsm-tool configure

[ovirt-users] Re: Upgrading Node that use Local Storage Domain

[Roman Bednar]

Hello,

it's always better to share logs showing the error message, that way we can
look at what exactly went wrong. But in general there is a guide [1] on
upgrading from 4.3 when using local storage.

If that's not the case there's also a chance your local storage domain is
not placed correctly [2].

If neither of those two help you resolve the issue please share the logs
with us and we'll look further.

I am using Zabbix and this simple plugin

there are probably more sophisticated solutions but this one serves me well

[ovirt-users] Re: Time Drift Issues

[Strahil Nikolov via Users]

I had similar issues where the battery of the motherboard was running out of 
'juice' and the hardware cloxk was just going crazy. NTP couldn't fix it , so a 
replacement of the battery was the only option.
