Title:
Can't attach a Volume to a VM with NetApp NFS Direct Driver
Status in OpenStack Compute (Nova):
Invalid
Bug description:
OS : Debian Wheezy
Nova version : 2.11.1.30.g8ac304f
OpenStack installed with DevStack.
I'm using a NetApp system for storing Volumes provided by NFS and
expose volumes to VMs with NFS too.
=== Scenario
cinder.conf :
(...)
nfs_shares_config = /etc/cinder/shares.conf
nfs_mount_point_base = /etc/cinder/volumes
volume_driver = cinder.volume.drivers.netapp.nfs.NetAppDirectCmodeNfsDriver
netapp_server_hostname = 10.X.X.X
netapp_server_port = 80
netapp_login = admin
netapp_password = secrete
netapp_transport_type = http
netapp_vserver = vs0
1) I can start cinder-volume and see that it mounts my NFS share (hosted on
NetApp) :
mount :
10.X.X.X:/voltest on /etc/cinder/volumes/44a3ed2e30a8aaf14a2ba926457f5666
type nfs4
(rw,relatime,vers=4,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.X.X.X,minorversion=0,local_lock=none,addr=10.X.X.X)
2) I can create a volume :
+--------------------------------------+-----------+--------------+------+-------------+----------+-------------+
| ID | Status | Display Name | Size |
Volume Type | Bootable | Attached to |
+--------------------------------------+-----------+--------------+------+-------------+----------+-------------+
| f2aae196-e6e4-4906-9f3f-153909c52f95 | available | None | 1 |
None | false | |
+--------------------------------------+-----------+--------------+------+-------------+----------+-------------+
3) Now I want to attach the volume to my VM and it fails.
Here is my nova-compute.log TRACE :
http://paste.openstack.org/show/5Xuo2ECF4O9cZt5unDOR/
It fails.
4) I want to attach the volume manually with virsh tool :
attach-volume instance-001 --source XXXX --target vdb
And it works ! I can manage the volume from the VM and put some
files.
=== Investigation
After investigation, I can see that the bug appears in Nova, here :
https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py#L888-912
My question : is it normal that we don't have a connector for NFS ? I only
see iSCSI & FC.
How is performed the mount ?
Other interesting point, it works with standard NFS driver. I can
create and attach volumes to VMs.
Let me know if you need more informations, I would like to know if
it's a bug or if I miss something on my configuration.
