I am running Cinder with my own iscsi based driver, the cinder-volume child process is re-trying again and again.

Here is the log of the cinder-volume:

Please, help ... :-)

Didn't you lost your iSCSI Connection?

From my iscsi driver perspective, my volume node won't start any iscsi services until create volume is done/called. BTW, whom do i have to connect to ?? iSCSI connection to which node ??

Oh wait, you're using your own Driver? I don't get it. So, here, I'll not be able to help you because I don't know what you develop how you did it etc, plus, I'm not so good in development on OpenStack.

yes i am using my own driver. Actually, i am developing my own volume service provider, where i will be providing volume from my node using iSCSI and via cinder i will expose my LUN. Please suggest where i would get help on this matter.

First of all, you probably should ask for a code review of your source on StackOverflow where Code Gurus stand and then, if everything is clean on your driver, you'll better go to the Openstack IRC Development channel.
