| nandersson | Hi, I saw the recording of Thomas Bushnell, Google on UDS. He made a strange remark. He said a reboot cost Google 1M USD - because they are tens of thousands of users and a reboot could take 15 min. This sounds strange. Does anybody know if they run their machines from NFS or something like that on Google??? | 11:33 |
| zyga | nandersson, maybe it means that it takes 15 minutes to reboot to a state you were in before | 11:35 |
| nandersson | zyga, I dont know. He also said "A logout is only half of that". It seemed to me that everyone was connected to the same server via NFS or something like that. | 11:39 |
| zyga | nandersson, again, perhaps that's the cost of going back to the all the open applications you are looking at | 11:39 |
| PatrickDK | a reboot of what? | 11:40 |
| PatrickDK | if a server, could be nfs, or http server, or many other things | 11:40 |
| PatrickDK | but that sounds like you don't have a failover server setup, otherwise it would be a max, of a min, not 15 | 11:40 |
| nandersson | PatrickDK, reboot of the users operating system (Goobuntu). Yeah, 15 min seems like a very long time. That is why I thought they might boot their machines from NFS or something. | 11:41 |
| PatrickDK | still doesn't matter, that is what failover is for | 11:42 |
| PatrickDK | I do iscsi boot, no local disks, and let that failover if I reboot the server | 11:42 |
| nandersson | PatrickDK, Yeah, it could be that Zyga is right. He might refer to boot back to a former state. | 11:43 |
| PatrickDK | sounds just completely nuts, if it costs you 1million to reboot, why not have a hot standby? that has got to be cheaper than 1million, for it's life | 11:43 |
| zyga | PatrickDK, hot standby on my current desktop state? | 11:43 |
| PatrickDK | yes, but if your booting back to a former state, and another server is handling the load | 11:43 |
| PatrickDK | how exactly could that add up to 1million? | 11:43 |
| zyga | and especially | 11:43 |
| zyga | I don't believe they meant servers | 11:44 |
| PatrickDK | oh for a user desktop? | 11:44 |
| zyga | the talk was about the desktop | 11:44 |
| PatrickDK | how does that affect thousands of users? | 11:44 |
| nandersson | Yeah, it didnt make any sense to me either. The talk was very interesting though. http://www.youtube.com/watch?feature=player_embedded&v=fu3pT_9nb8o#! | 11:44 |
| nandersson | Yeah, it was about the desktop | 11:44 |
| nandersson | In the same talk Thomas Busnell made a lot of remarks on Ubuntu Automated Testing, but I wonder - does it make sense for Google to test to compile the source code at all times to see if it breaks, dependencies fail, or what is that purpose? I guess Google would mainly be interested in seeing that the binaries work, and doesnt break any dependencies, that upgrades works, etcetera. Are those functions incorporated in Ubuntu Automated Testing? | 11:57 |

| patdk-wk | oh | 12:45 |
| patdk-wk | he is talking total | 12:45 |
| patdk-wk | 15min per user * thousands of desktops = 1Million cost | 12:46 |
| patdk-wk | not 1million per desktop | 12:46 |
| patdk-wk | or per reboot | 12:46 |

| stgraber | please ignore the new desktop images, they were just a mistake. 20120604.2 is still the one that needs testing | 18:45 |
| balloons | stgraber, whew.. :-) I was wondering | 19:07 |
| stgraber | balloons: yeah, both slangasek and I were building the same images ;) | 19:07 |
| balloons | stgraber, ohh, btw.. i guess we normally kill the dailies off during milestones, but now I can't get my reporting info for last week :-( Guess I need that db access | 19:08 |
| stgraber | balloons: I can mark them as "released" if you want, so they show up but are read-only | 19:08 |
| balloons | well, I mean, the results are hidden from me and everyone else.. it's an interesting conundrum. I don't want to confuse people | 19:09 |
| balloons | i've added it to my notes stgraber.. we'll discuss post-alpha 1 | 19:14 |
| stgraber | balloons: actually, can you pastebin that script (I don't seem to have it around anymore), I think it should be easy to have it look a the archived milestones too | 19:15 |
| balloons | stgraber, d'oh! i'm too scatterbrained today.. lololololol | 19:17 |
| balloons | I was thinking it WASN'T in the archived runs | 19:17 |
| balloons | hence, my issues with not being able to get at stuff | 19:18 |
| balloons | I can pastebin the script anyways, if you'd like.. i started modifying it a bit, and then as we spoke about, decided it would be better to expend efforts towards getting a report into the interface itself | 19:19 |
