The host itself looks ok
downtimed in Icinga for an hour.. mgmt and server and all services on them.
first attempt the server came back just fine but mgmt was not fixed yet. we are trying a second time and leave it off longer.
@Jclark-ctr checked on this. (Thanks!) but this still needs to happen. One minute i could SSH to it just fine and 12 minutes later it was alerting in Icinga again. So it keeps being "from time to time" and Chris' comment " we will need to power off the host for 10-30secs." still stands.
I checked it was already repooled meanwhile by somebody and ACKed it in Icinga.
Agreed with Jclark we can do it next week when he is back onsite. It's not urgent.
