Hi Johan, Can you please run something like this on the spm node? while true; do echo `date; ps ax | grep -i remotefilehandler | wc -l` >> /tmp/handler_num.txt; sleep 1; done
When it'll happen again, please stop the script, and write here the maximum number and the time that it happened. Also, please check if "process_pool_max_slots_per_domain" is defined in /etc/vdsm/vdsm.conf, and if so, what's the value? (if it's not defined there, the default is 10) Thanks! ----- Original Message ----- > From: "Johan Kooijman" <m...@johankooijman.com> > To: "Meital Bourvine" <mbour...@redhat.com> > Cc: "users" <users@ovirt.org> > Sent: Tuesday, February 18, 2014 2:55:11 PM > Subject: Re: [Users] Nodes lose storage at random > To follow up on this: The setup has only ~80 VM's active right now.
