New issue 923 by [email protected]: running replace-disks on instance
with new installed secondary node failes
https://code.google.com/p/ganeti/issues/detail?id=923
What software version are you running? Please provide the output of "gnt-
cluster --version", "gnt-cluster version", and "hspace --version".
gnt-cluster version
Software version: 2.11.3
Internode protocol: 2110000
Configuration format: 2110000
OS api version: 20
Export interface: 0
VCS version: (ganeti) version v2.11.3
What distribution are you using?
ubuntu 14.04
What steps will reproduce the problem?
if i restore a node which was secondary for some instances and try to
run "gnt-instance replace-disks -a instance1" ganeti say i should run
activate-disks:
root@vserver12:~# gnt-instance replace-disks -a instance1
Thu Aug 21 12:48:47 2014 - INFO: Checking disk/0 on vserver12
Thu Aug 21 12:48:47 2014 - INFO: Checking disk/0 on vserver6
Failure: prerequisites not met for this operation:
error type: wrong_state, error details:
Please run activate-disks on instance instance1 first
but this failes because the restored node does not have the needed lvs for
the instance:
root@vserver12:~# gnt-instance activate-disks instance1

i've tried this on an older two node cluster with ganeti 2.10.1 and it
works.
1. i've created a new drbd test instance with --no-start
2. i've manually removed all instance lvs on the secondary node
3. i've started the instance with -f
4. i run the replace-disks -a command
the same steps on the ganeti 2.11.3 cluster do not work like described
above.
