[ovirt-users] New host HE 4.0 -> [ ERROR ] Failed to execute stage 'Environment customization': Specified gateway is not pingable

[Matt .]

Hi,

It was indeed NetApp, and as you say I can remember something like it
but I'm not 200% sure.

For some host that I wasn't able to remove I needed hosted-engine
--reinitialize-lockspace indeed, figured that out.

dd over the same went well, didn't see anyone complaining about that either.

Thanks Didi for upodating this post.
