Re: [ovirt-users] Ovirt backups lead to unresponsive VM

Hi Alex, Sorry for the mail's delay. From a brief look at your logs, I've noticed that the error you've got at the engine's log was logged at 2018-02-03 00:22:56, while your vdsm's log ends at 2018-02-03 00:01:01. Is there a way you can reproduce a fuller vdsm log? *Regards,* *Shani Leviim* On Sat, Feb 3, 2018 at 5:41 PM, Alex K <rightkicktech(a)gmail.com&gt; wrote: > Attaching vdm log from host that trigerred the error, where the Vm that > was being cloned was running at that time. > > thanx, > Alex > > On Sat, Feb 3, 2018 at 5:20 PM, Yaniv Kaul <ykaul(a)redhat.com&gt; wrote: > >> >> >> On Feb 3, 2018 3:24 PM, "Alex K" <rightkicktech(a)gmail.com&gt; wrote: >> >> Hi All, >> >> I have reproduced the backups failure.
