Re: [Rdo-list] [RDO-Manager] Solving "nova is locked" errors from Ironic

Hi all, So, Ironic task manager is attacking us again: https://bugzilla.redhat.com/show_bug.cgi?id=1233452 Previously we already had https://bugzilla.redhat.com/show_bug.cgi?id=1212134 I've implemented retries upstream in ironicclient and backported to our packages. Later I had to bump the retry timeout in instack-undercloud to 1 minute: https://github.com/rdo-management/instack-undercloud/blob/master/scripts/... Now we have the same problem in another place and I wonder how to fix it. I have 2 obvious idea: 1. Patch ironicclient to have longer default timeout (2 mins?) 2. Update stackrc to carry longer IRONIC_MAX_RETRIES and IRONIC_RETRY_INTERVAL I'd prefer the latter, as it does not touch ironicclient package, only undercloud installation tool. It can also be changed more easily in run time. WDYT? I wonder what the root cause is as well. I suspect some very slow BMC's take too much time to do power actions or power syncs. It's possible we'll make a wrong guess, and the problem will persist despite becoming rare.
