New issue 615 by [email protected]: gnt-node evacuate -p fails if a node is
in state 'drained'
http://code.google.com/p/ganeti/issues/detail?id=615
What software version are you running? Please provide the output of "gnt-
cluster --version", "gnt-cluster version", and "hspace --version".
2.6.2
What distribution are you using?
Debian
What steps will reproduce the problem?
1. Set a node to 'drained' (e.g. gnt-node modify -D yes $NODE)
2. Run 'gnt-node evacuate -p $NODE'
3.
What is the expected output? What do you see instead?
I expected that the instances on the node would be evacuated, instead, I
see this:
[Unable to evacuate instances $instance1 (FailDisk), $instance2 (FailDisk),
instance3 (FailDisk)]
If I instead "undrain" the node and then retry the 'gnt-node evacuate -p'
command, it is successful.
It seems like Ganeti should allow these types of operational tasks to occur
for nodes that have been drained. The drain should not allow "new"
instances to be put on the node, but it should definitely allow
administrators to move stuff off of the node (i.e. all
evac/failover/migrate operations should work for a node in state 'drained').
