You’re still only one power outage away from losing your state, but ideally a clean install and running the same scripts again could mostly recover. With that said most of what I’d been working on has a noop result if the same command is repeated multiple times (like “openstack role create”), so slowly appending to the script and just rerunning it in its entirety was a completely fine workflow. If you’re doing stuff where that’s not the case, this will not be a good solution.</div><div><br></div><div>Tim</div><div><br></div><span id="OLK_SRC_BODY_SECTION"><div style="font-family:Calibri; font-size:11pt; text-align:left; color:black; BORDER-BOTTOM: medium none; BORDER-LEFT: medium none; PADDING-BOTTOM: 0in; PADDING-LEFT: 0in; PADDING-RIGHT: 0in; BORDER-TOP: #b5c4df 1pt solid; BORDER-RIGHT: medium none; PADDING-TOP: 3pt"><span style="font-weight:bold">From: </span> Kevin Benton <<a href="mailto:kevin@benton.pub">kevin@benton.pub</a>><br><span style="font-weight:bold">Reply-To: </span> "OpenStack Development Mailing List (not for usage questions)" <<a href="mailto:openstack-dev@lists.openstack.org">openstack-dev@lists.openstack.org</a>><br><span style="font-weight:bold">Date: </span> Monday, May 2, 2016 at 3:10 PM<br><span style="font-weight:bold">To: </span> "<a href="mailto:openstack-dev@lists.openstack.org">openstack-dev@lists.openstack.org</a>" <<a href="mailto:openstack-dev@lists.openstack.org">openstack-dev@lists.openstack.org</a>><br><span style="font-weight:bold">Subject: </span> [openstack-dev] [devstack] - suggested development workflow without ./rejoin-stack.sh ?<br></div><div><br></div><div dir="ltr">This patch removed the ./rejoin-stack.sh script: <a href="https://review.openstack.org/#/c/291453/">https://review.openstack.org/#/c/291453/</a><div><br></div><div>I relied on this heavily in my development VM which sees lots of restarts because of various things (VM becomes unresponsive in load testing, my laptop has a kernel panic, etc).
