New issue 457 by [email protected]: gnt-cluster verify does not detect
StandAlone DRBD resources.
http://code.google.com/p/ganeti/issues/detail?id=457
What software version are you running? Please provide the output of "gnt-
cluster --version" and "gnt-cluster version".
# gnt-cluster --version
gnt-cluster (ganeti v2.7.0beta3) 2.7.0~beta3
# gnt-cluster version
Software version: 2.7.0~beta3
Internode protocol: 2070000
Configuration format: 2070000
OS api version: 20
Export interface: 0
What distribution are you using?
Debian Wheezy
What steps will reproduce the problem?
1. Intentionally put the cluster into a split-brain state.
2. Fix (to the extent possible) the split-brain issue.
3. Run 'gnt-cluster verify'
What is the expected output? What do you see instead?
gnt-cluster verify should complain about the StandAlone DRBD resources. And
in fact any attempt to migrate or failover instances does not work.
gnt-instance info also detects the situation. But gnt-cluster verify does
not complain. Neither does gnt-cluster verify-disks
Please provide any additional information below.
