Comment #1 on issue 851 by [email protected]: gnt-cluster verify leaves out
one node on N+1 Memory redundancy
http://code.google.com/p/ganeti/issues/detail?id=851
Hi!
We need more information here.
Can you please provide how big the instances are that are running on the
cluster when this message gets created?
Please also provide the output of:
gnt-node list
gnt-instance list
I am also not entirely sure what you mean with 'leaves out one node'? When
you have only 2 nodes, the n+1 redundancy is tested under the assumption
that one of the instances running on the other node fails over. So it
checks for node1 "do I have enough ram in case instance X on node2 fails"
and vice versa (for all instances). If the nodes don't have enough memory
to accommodate the biggest instance of the other node, this message appears.
Thanks,
Helga
