Hi everyone,I setup a ceph cluster and I use the RBD driver for nova-volume. I can create volumes and snapshots but currently I can't attach them to an instance. Apparently the volume is detected as busy but it's not, no matter which name I choose. I tried from horizon and the command line, same issue. $ nova --debug volume-attach de3743be-69be-4ec3-8de3-fc7df6903a97 12 /dev/vdc connect: (localhost, 5000) send: 'POST /v2.0/tokens HTTP/1.1\r\nHost: localhost:5000\r\nContent-Length: 100\r\ncontent-type: application/json\r\naccept-encoding: gzip, deflate\r\naccept: application/json\r\nuser-agent: python-novaclient\r\n\r\n{"auth": {"tenantName": "admin", "passwordCredentials": {"username": "admin", "password": "admin"}}}' reply: 'HTTP/1.1 200 OK\r\n' header: Content-Type: application/json header: Vary: X-Auth-Token header: Date: Fri, 25 May 2012 08:29:46 GMT header: Transfer-Encoding: chunked connect: (172.17.1.6, 8774) send: u'GET /v2/d1f5d27ccf594cdbb034c8a4123494e9/servers/de3743be-69be-4ec3-8de3-fc7df6903a97 HTTP/1.1\r\nHost: 172.17.1.6:8774 <http://172.17.1.6:8774>\r\nx-auth-project-id: admin\r\nx-auth-token: 37ff6354b9114178889128175494c666\r\naccept-encoding: gzip, deflate\r\naccept: application/json\r\nuser-agent: python-novaclient\r\n\r\n' reply: 'HTTP/1.1 200 OK\r\n' header: X-Compute-Request-Id: req-fc7686dd-7dff-4ea2-b2dd-be584dadb7c1 header: Content-Type: application/json header: Content-Length: 1371 header: Date: Fri, 25 May 2012 08:29:46 GMT send: u'POST /v2/d1f5d27ccf594cdbb034c8a4123494e9/servers/de3743be-69be-4ec3-8de3-fc7df6903a97/os-volume_attachments HTTP/1.1\r\nHost: 172.17.1.6:8774 <http://172.17.1.6:8774>\r\nContent-Length: 60\r\nx-auth-project-id: admin\r\naccept-encoding: gzip, deflate\r\naccept: application/json\r\nx-auth-token: 37ff6354b9114178889128175494c666\r\nuser-agent: python-novaclient\r\ncontent-type: application/json\r\n\r\n{"volumeAttachment": {"device": "/dev/vdc", "volumeId": 12}}' reply: 'HTTP/1.1 200 OK\r\n' header: X-Compute-Request-Id: req-4a22f603-4aad-4ae9-99a2-6a7bcacf974f header: Content-Type: application/json header: Content-Length: 48 header: Date: Fri, 25 May 2012 08:29:46 GMT $ echo $? 0 See the logs here: http://paste.openstack.org/show/18163/
Hi Seb, It looks like the DeviceIsBusy exception is raised when libvirt returns failure for any reason when attaching a volume. Try turning on debug logging for libvirt and attaching again, and posting the logs from libvirt. You might need to upgrade libvirt - the version in Ubuntu 12.04 should work, or upstream libvirt 0.9.12. Josh
If you need more information let me know :) Thank you in advance. Cheers. ~Seb
