Comment #2 on issue 861 by [email protected]: hspace incorrectly reports no
instance can be allocated when one node group is not N+1 happy
http://code.google.com/p/ganeti/issues/detail?id=861
Technically, this is a feature request. The specification of hspace says
"...while maintaining N+1 status" which can be interpreted as not allocating
any instances if the cluster is not N+1 happy in the first place.
Nevertheless, there is the need to correctly estimate the capacity of a
cluster
even if one group is not N+1 happy. So I will add two new options to hspace
- one allowing to consider the groups independently, i.e., if a node group
contains at least one not N+1 happy node, no instances are allocated in
this group, but other groups are allocated as usual. This should be the
most useful way of calling hspace in practise
- another one allowing to extreme and consider all allocations that do not
cause any new N+1 violations (and do not allocate on not N+1 happy nodes);
this might overestimate the cluster capacity in completely unbalanced
clusters.
