Hello,

I set the host to maintenance mode and tried to undeploy engine via GUI. The action in GUI doesn't show an error but afterwards it still shows only "Undeploy" on hosted-engine tab od the host.

Even removing the host from the cluster doesn't work because the GUI says "The hosts maekred with * still have hosted engine deployed on them. Hosted engine should be undeployed before they are removed"

Yes, sorry: it's now a two step process, you have first to undeploy hosted-engine from the host and only then you could remove the host.

 

Bye

Hello,

I have set up 3 hosts for engine, 2 of them are working correct. There is no other host even having broker/agent installed. Is it possible that the error occurs because the hosts are multihomed (Management IP, IP for storage) and can communicate with different IP's ?

Having multiple logical networks for storage, management and so on is a good practice and it's advised so I tend to exclude any issue there.
The point is why your microcloud27.sub.mydomain.de fails acquiring a lock as host 3.
Probably the simplest fix is just setting it in maintenance mode from the engine, removing it and deploying it from the engine as an hosted engine host again.
