This is what we do. That said, I do agree with Kostiantyn though. Yes, clocks shouldn't drift, but it happens. If there is a known, reproduceable problem than negatively effects the cluster, it should be fixed.
Now, if this problem turns out to be complex and time consuming to fix, I do see an argument for it being filed as "low priority", but it should be in the "To Fix" queue. digimer On 28/08/15 05:31 AM, Vladislav Bogdanov wrote: > 28.08.2015 12:25, Kostiantyn Ponomarenko wrote: >> In my case the final solution will be shipped to different counties >> which means different time zones. > > Why not to keep all HW clocks in UTC? > >> And the replacement of one of the nodes in the working solution could >> happens. >> So the possibilities of the issue to happen is still there. >> >> Thank you, >> Kostya >> >> On Fri, Aug 28, 2015 at 10:02 AM, Andrew Beekhof <and...@beekhof.net >> <mailto:and...@beekhof.net>> wrote: >> >> >> > On 21 Aug 2015, at 11:06 pm, Kostiantyn Ponomarenko >> <konstantin.ponomare...@gmail.com >> <mailto:konstantin.ponomare...@gmail.com>> wrote: >> > >> > As I wrote in the previous email, it could happen when NTP >> servers are unreachable before Pacemaker's start, and then, after some >> time, NTP becomes reachable again. >> > So it is possible that time will be synchronized in any >> direction: 15 min or 23 min or 1 hour or 12 hours backward/forward. >> >> If your clock is drifting by hours during a reboot cycle, then I >> would suggest you have a hardware issue that needs attending to. >> >> > And in that case the bug will appear itself. >> > >> > Thank you, >> > Kostya >> > >> > On Mon, Aug 17, 2015 at 3:01 AM, Andrew Beekhof >> <and...@beekhof.net <mailto:and...@beekhof.net>> wrote: >> > >> > > On 8 Aug 2015, at 12:43 am, Kostiantyn Ponomarenko >> <konstantin.ponomare...@gmail.com >> <mailto:konstantin.ponomare...@gmail.com>> wrote: >> > > >> > > Hi Andrew, >> > > >> > > So the issue is: >> > > >> > > Having one node up and running, set time on the node backward >> to, say, 15 min (generally more than 10 min), then do "stop" for a >> resource. >> > > That leads to the next - the cluster fails the resource once, >> then shows it as "started", but the resource actually remains >> "stopped". >> > > >> > > Do you need more input from me on the issue? >> > >> > I think “why” :) >> > >> > I’m struggling to imagine why this would need to happen. >> > >> > > >> > > Thank you, >> > > Kostya >> > > >> > > On Wed, Aug 5, 2015 at 3:01 AM, Andrew Beekhof >> <and...@beekhof.net <mailto:and...@beekhof.net>> wrote: >> > > >> > > > On 4 Aug 2015, at 7:31 pm, Kostiantyn Ponomarenko >> <konstantin.ponomare...@gmail.com >> <mailto:konstantin.ponomare...@gmail.com>> wrote: >> > > > >> > > > >> > > > On Tue, Aug 4, 2015 at 3:57 AM, Andrew Beekhof >> <and...@beekhof.net <mailto:and...@beekhof.net>> wrote: >> > > > Github might be another. >> > > > >> > > > I am not able to open an issue/bug here >> https://github.com/ClusterLabs/pacemaker >> > > >> > > Oh, for pacemaker bugs see http://clusterlabs.org/help.html >> > > Can someone clearly state what the issue is?
