New issue 951 by [email protected]: gnt-node evacuate on a downed, offline
node is behaving oddly
https://code.google.com/p/ganeti/issues/detail?id=951
gnt-cluster (ganeti v2.11.5) 2.11.5
Software version: 2.11.5
Internode protocol: 2110000
Configuration format: 2110000
OS api version: 20
Export interface: 0
VCS version: (ganeti) version v2.11.5
hspace (ganeti) version v2.11.5
compiled with ghc 7.4
running on linux x86_64
Debian 7.4
Problem:
3 node cluster, (c0,c1,c2).There is 1 active DRBD primary instance on c1
Then c1 is shutdown:
root@c0:~# gnt-node list
Node DTotal DFree MTotal MNode MFree Pinst Sinst
c0.ws.nsrc.org 30.0G 27.9G 1.5G 238M 1.3G 0 1
c1.ws.nsrc.org ? ? ? ? ? 1 0
c2.ws.nsrc.org 30.0G 30.0G 1.5G 87M 1.4G 0 0
I offline c1:
root@c0:~# gnt-node modify --offline=yes c1

Modified node c1
- master_candidate -> False
- offline -> True
I then attempt a "gnt-node evacuate -p c1":
root@c0:~/gnt-node-evacuate# gnt-node evacuate -p c1
Relocate instance(s) wordpressx from node(s) c1?
y/[n]/?: y
Thu Sep 18 20:13:09 2014 - INFO: Evacuating instances from
node 'c1.ws.nsrc.org': wordpressx
Thu Sep 18 20:13:09 2014 - WARNING: Unable to evacuate instances
wordpressx (FailDisk)
Failure: command execution error:
Unable to evacuate instances wordpressx (FailDisk)
What is the expected output? What do you see instead?
Was expecting to be told that the node cannot be evacuated because it's
down.
Arguably, I should be using gnt-node failover, but the response (FailDisk)
leads me to believe something
is not right.
