Some more trouble shooting on this (and still no progress) I see this when I reboot (or use targetcli which is below this log):

Hi all,

Im keeping on keeping on with this - now this error. Ive created volumes just fine on another node (block1):

[block1 etc]# cinder list


|                  ID                  |   Status  | Display Name | Size | Volume Type | Bootable | Attached to |


| 4c6e1b15-2c7e-4bca-aae4-925cc054db8d | available |   myVolume   |  1   |     None    |  false   |             |

| 5c19f39c-445f-4de3-8f79-266f16bc1f01 | available |    test2     |  5   |     None    |  false   |             |

But when I goto try and add to an existing instance it always fails with the same errors below. Ive been searching around to see if I could find anything to help but no luck. Anyone solve the same issue I would really appreciate the insight. Just an fyi, I believe everything is working in my stack except for name resolution (I cant nslookup from my instances so dont know if anything is incorrect with the networking still working on that as well) which I dont think is interfering with any of this.

From the lhe logs the things that standout the most: 2

are you trying to attach the volume before the instance is finished booting? I've run into timing issues around that. If you do a soft reboot of the instance does it then attach?

HI Bob thanks for helping. Yeah tried that and just to make sure tried it again (soft reboot) and made sure instance is up but same errors.

I had a different problem with iscsiadm port 3260 because cinder was not usin the neutron management network but instead a different external address for the cinder host causing firwall to block the port. I added my_ip=10.0.0.xx to /etc/cinder/cinder.conf and verified firewall allowed access.

Thanks rl - I have that defined as well and still same error. I defined the following to the block node ip:




Keep getting the same error! Very confusing.

One other thing not mentioned in the install guide that I needed to do to get cinder to work is add iscsi_helper=tgtadm to cinder.conf on the cinder hosts.
