i've increased the limit and then restarted agent and broker. status normalize, but then right now it went to "False" state again but still both having 2400 score. agent logs remains the same, with "ovirt-ha-agent dead but subsys locked" status. ha-broker logs below

Thanks,

ok, now it seems that broker runs fine, so I need the recent agent.log
to debug it more.

Hi Guys,
I need help with my ovirt Hosted-Engine HA setup. I am running on 2
ovirt hosts and 2 gluster nodes with replicated volumes. i already have

restarting ha-broker and ha-agent normalizes the status but eventually
it would become "false" and then return to the result above. hope you
guys could help me with this.
Hi Jaicel,
please attach agent.log and broker.log from the host where you trying to
run hosted-engine --vm-status. I have a feeling that you ran into a
known problem on gluster - stalled file descriptor, in that case the
only known solution at this time is to restart the broker & agent as you
have already found out.
Adding Niels and gluster-devel to troubleshoot from Gluster NFS perspective.
I'd welcome any details on this "stalled file descriptor" problem. Is
there a bug filed with some details like logs, sysrq-t and maybe even
tcpdumps? If there is an easy way to reproduce this behaviour, I can
surely look into it and hopefully come up with some advise or fix.
Thanks,
Niels
