It seems like I am hitting this issue from release 3.6.0:

If cluster is updated to compatibility version 3.6 while hosts that =
have not been
upgraded, i.e with emulated machine flags that do not =
match cluster compatibility version 3.6, you might end up with incorrect =
emulated machine flag on the cluster. As a result, you will not be able =
to run VMs. Possible workarounds would be to to reset the emulated =
machine on the cluster (requires putting all the hosts into maintenance) =
or disable the host-plug memory feature in the database.
the latter is not a correct solution and should not be encouraged.
I clicked "reset emulated machines" on the cluster, while
in =
maintenance mode. I checked vds_dynamic for the host, and found the =
columns supported_cluster_levels and supported_engine_levels to both be =
missing version 3.6.

Hi,

can anyone explain what this button does? I have looked in the =

I have a cluster version 3.6.2 that will not Activate the host because =
the
message "Host .. is compatible with versions =
(3.0,3.1,3.2,3.3,3.4,3.5) and cannot join Cluster...". The host was =
part of a 3.5 cluster until the upgrade to 3.6.2.

Thanks a million,
