I tried your 'Try restore old certificates and simply run again engine-setup' but
the validation fails with:
---------------------------------------------------------------------------------------------------------------------------------------------------------
[ ERROR ] It seems that you are running your engine inside of the hosted-engine VM and are
not in "Global Maint
enance" mode.
In that case you should put the system into the "Global Maintenance"
mode before running engine-setup,
or the hosted-engine HA agent might kill the machine, which might
corrupt your data.
[ ERROR ] Failed to execute stage 'Setup validation': Hosted Engine setup
detected, but Global Maintenance is n
ot set.
---------------------------------------------------------------------------------------------------------------------------------------------------------
even though I have placed it into Global Maintenance mode.
The problem is that all 3 hosts are currently 'Non Responsive'
FYI - In another environment where the vdsm certificates had expired on one of 2 clusters,
copying the certs from a host in the other cluster allowed the hosts to become responsive
so I could 'Enroll certificates'.
