Hello,
I have a 4.4.8 host that results as nonresponsive.
The DC is FC based
Tried to restart some daemons without effect (vdsmd, mom-vdsmd wdmd)
Then I executed a ssh host reboot but it seems it continues this way after
rebooting
From storage and network point of view it seems all ok on the host.
In vdsm.log of the host I see every 5 seconds:

I would like to try to put into maintenance the host and then activate, or
reinstall, but there is a power action still in place since 1 hour ago
(when I executed ssh host reboot attempt that got host rebooted but not
connected apparently) that prevents it... what is its timeout?
WHat can I check to understand the source of these supposed communication
problems?
Thanks,

Try restarting libvirtd. It will also restart vdsmd, sometimes that fixes things for me
when there has been a storage hiccup.
If it’s a HA Engine host, I’ve also had to restart the ha-agent/ha-broker combo is some
situations as well.

Thanks for the suggestion, but with the "ssh host restart" action actually
the server has restarted completely, so I doubt it can be that
If it’s a HA Engine host, I’ve also had to restart the
ha-agent/ha-broker
combo is some situations as well.
No, it's an external engine
On the host:
[root@ov300 vdsm]# nodectl check
Status: OK
Bootloader ... OK
Layer boot entries ... OK
Valid boot entries ... OK
Mount points ... OK
Separate /var ... OK
Discard is used ... OK
Basic storage ... OK
Initialized VG ... OK
Initialized Thin Pool ... OK
Initialized LVs ... OK
Thin storage ... OK
Checking available space in thinpool ... OK
Checking thinpool auto-extend ... OK
vdsmd ... OK
[root@rhvh300 vdsm]#
I already had the idea to try restarting the engine server, and then I
found this similar bugzilla (even if for an older release):
https://access.redhat.com/solutions/4222911
RHV host in "not responding" state until ovirt-engine service restarted
I rebooted the engine server (that is a VM inside a vSphere environment)
and all came back good with the host set as up, together with the other
ones.....
