Description of problem:
Openstack on rhel 7.0 VM box
rhos 5.0 version .
After creating instance , we try to attach volume to it .
The volume created by tempest code :
def test_attach_detach_volume_to_instance(self):
# Volume is attached and detached successfully from an instance
mountpoint = '/dev/vdc'
_, body = self.client.attach_volume(self.volume['id'],
self.server['id'],
mountpoint)
After volume has been created , we are attaching it to instance .
The result of this action is that cinder shows that the volume attached to
instance .
But in nova - instace we do not see the volume in lsblk output .
We get error from logs :
/var/log/nova/nova-compute.log:136:2014-09-08 02:59:39.573 31416 DEBUG
nova.virt.disk.api [req-c0039d74-1c31-4e19-8719-bf3fb8eca505

/var/lib/nova/instances/5531d5a9-cefd-4873-bbca-bdd4336ca5a8/disk with
libguestfs (mount_options: /dev/sda on / (options: ''): mount: /dev/sda is
write-protected, mounting read-only
I attached another volume with auto mount point .
When we delete the instacne the cinder is binded to deleted instance and we can
not delete the volume.
Version-Release number of selected component (if applicable):
How reproducible:
#1 Create instance
#2 create volume with tempest code based on :
def test_attach_detach_volume_to_instance(self):
# Volume is attached and detached successfully from an instance
mountpoint = '/dev/vdc'
_, body = self.client.attach_volume(self.volume['id'],
self.server['id'],
mountpoint)
#2 the volume is attached , but we dont see it in instance (cirros image)
#3 attach another volume with auto mount point to instance
#4 delete the instance
#5 at this point cinder attachment is to "not existing" instance and we are not
able to delete the volume.
