Re: [Openstack] Nova Volume and provisionning on iSCSI SAN

2012-08-02 Thread Thomas, Duncan
I guess you might need to port one of the other iSCSI-based drivers (e.g. lefthand) to use whatever creation/deletion/access control mechanisms your Dell SAN uses... This does not look to be a significant amount of work, but such commands aren't generally standardized so would need to be done

2012-07-12 Thread Thomas, Duncan
We've got volumes in production, and while I'd be more comfortable with option 2 for the reasons you list below, plus the fact that cinder is fundamentally new code with totally new HA and reliability work needing to be done (particularly for the API endpoint), it sounds like the majority is

Re: [Openstack] Deleting a volume stuck in attaching state?

2012-06-20 Thread Thomas, Duncan
nova-manage volume delete on a nova host works for this, though if the attach operation is still underway then this might cause some weirdness. If the attach cast to nova compute has timeouted out or been lost / errored then nova-manage volume delete should do the job. -- Duncan Thomas HP

Re: [Openstack] Invoking Nova commands remotely

2012-06-08 Thread Thomas, Duncan
nova list and other nova * commands work by making http (or https) connections to your api node. Any node that has network access to it can make calls just fine as long as you've got the right environment variables set, which include: NOVA_URL, NOVA_PROJECT_ID, NOVA_USERNAME etc. nova-manage

Re: [Openstack] [nova][glance] making nova api more asynchronous

2012-06-08 Thread Thomas, Duncan
The weakness of all of our current async calls (e.g. nova boot) is that there is no route to get the details of what failed... when my sever comes up in 'error', I'd really like to know why... is it a system error? Broken image? Temporary glitch? There doesn't seem to be a channel for this kind
