Title:
nova rescue fails if connection made before RESCUE state
Status in OpenStack Compute (Nova):
Expired
Bug description:
Issue reported by one of our users in our Trusty/Icehouse controller +
Precise/Havana compute + nova-network cloud:
---
If I put the instance into rescue mode:
$ nova rescue 598ec2ba-9d87-484d-ae3a-4661b4be3d91
And then *immediately* try to ssh in:
$ ssh [email protected] -i ~/.ssh/some_key.pem
I get no errors, but even if I get a connection refused message, the
instance does not go into rescue mode properly.
However, if I put the instance into rescue mode:
$ nova rescue 598ec2ba-9d87-484d-ae3a-4661b4be3d91
And then wait until Nova list tells me that the instance is in rescue mode:
$ nova list
+--------------------------------------+---------+--------+------------+-------------+-------------------+
| ID | Name | Status | Task State |
Power State | Networks |
+--------------------------------------+---------+--------+------------+-------------+-------------------+
| 598ec2ba-9d87-484d-ae3a-4661b4be3d91 | tester2 | RESCUE | - |
Running | public= |
+--------------------------------------+---------+--------+------------+-------------+-------------------+
& only then ssh in, everything is sweetness and light.
So to my untrained eye, it would appear that eagerly ssh'ing in to the
instance is affecting the rescue operation.
---
Console log for the instance shows:
An error occurred while mounting /mnt.
keys:Press S to skip mounting or M for manual recovery
Looks like it failed to mount the rescue disk partition at /dev/vda1
and instead mounts /dev/vdb1 as the root disk, which is the disk from
the original instance being rescued:
Filesystem Size Used Avail Use% Mounted on
/dev/vdb1 9.8G 833M 8.4G 9% /
I can mount /dev/vda1 to /mnt manually and it looks like an untouched
ubuntu image.
