| 11:20:27 | sean-k-mooney | ya in ireland all the fiber is own by eirgrid and they do direct connection to houses but then aggreate mutiple frequense over the same fiber link only after that | |
| 11:20:58 | artom_ | I thought DSLAM was for DSL | |
| 11:22:13 | sean-k-mooney | i belive there is an optical version of it too that | |
| 11:22:32 | bauzas | sean-k-mooney: sorry, I only know the french terms, but do you know whether the fibers are mixed between the ISP and your home or not ? | |
| 11:22:35 | sean-k-mooney | dslam is the acronmy for the copper dsl version | |
| 11:22:51 | bauzas | sorry, french terms here https://lafibre.info/gpon/comprendre-les-differences-entre-la-fibre-gpon-p2p-active-ethernet-fttla/ | |
| 11:23:02 | bauzas | gpon fiber vs. p2p fiber | |
| 11:23:42 | bauzas | ie. we don't have with p2p fiber some cabinets in the streets for mixing fibers | |
| 11:24:14 | sean-k-mooney | bauzas: all our fiber is manage seperatly form the isps and there is no mixing between me and then first level aggration site so my fiber link goes dirctly to a fiber switch | |
| 11:24:15 | bauzas | we have straight large optic cables that can take 800 lines each | |
| 11:24:27 | bauzas | sean-k-mooney: ok so like me | |
| 11:24:54 | bauzas | but yeah, here is the same | |
| 11:25:10 | sean-k-mooney | so as long as the uplinks to that switch are not messed with my neigbors can get fiber installed lighting up one of the dark strands without impact | |
| 11:25:14 | bauzas | one operator is responsable for managing a city network | |
| 11:25:20 | sean-k-mooney | if that switch dies we all get taken out | |
| 11:25:38 | bauzas | and then ISPs are only responsible for the connectivity to the last mile | |
| 11:26:21 | bauzas | oh wait, then you have active internet ftth | |
| 11:26:32 | bauzas | a local switch located in a street cabinet | |
| 11:26:49 | sean-k-mooney | its within 10km or so | |
| 11:27:14 | opendevreview | Lee Yarwood proposed openstack/nova master: Add two new hacking rules https://review.opendev.org/c/openstack/nova/+/805668 | |
| 11:27:32 | sean-k-mooney | but ya it depends on desity where i am its likely closer due to the population desity | |
| 11:27:54 | bauzas | very interesting | |
| 11:28:04 | bauzas | I'm afraid to only knowing french terminologies | |
| 11:28:21 | bauzas | but at least, I know my SPOFs | |
| 11:28:37 | sean-k-mooney | i did not see a fiber cabinet comming into where i live but there is likely one on the road within a km or so | |
| 11:29:11 | bauzas | that's something you should take interest | |
| 11:29:47 | bauzas | as for example, depending on the deployment technology, you could be limited with bandwitdh upgrades | |
| 11:30:00 | bauzas | ie. a GPON FTTH is limited because this is mixed | |
| 11:30:18 | bauzas | you can only adress 2.5 Gbps per client | |
| 11:31:07 | bauzas | while with P2P, changing the bandwidth is only an ISP question | |
| 11:31:17 | gibi | who needs more than 2.5 Gpbs? | |
| 11:32:02 | sean-k-mooney | bauzas: i think technially i can get 10G if i needed too although i might need to replace the optical terminator on my side | |
| 11:32:22 | bauzas | gibi: :D | |
| 11:32:30 | sean-k-mooney | they are currently only trilaing grater then 1G is some areas | |
| 11:32:35 | sean-k-mooney | i dont think mine is one of them | |
| 11:32:48 | bauzas | gibi: trust me, I'm sometimes exhausting my 1gbps connection | |
| 11:32:52 | gibi | I know the joke about 64Kb but honestly 2.5Gpb?! | |
| 11:33:12 | gibi | bauzas: do you download to /dev/null? :D | |
| 11:33:33 | bauzas | I'm tempted to choose another ISP that proposes 2.5Gbps on two NICs | |
| 11:33:41 | bauzas | so I could load-balance | |
| 11:34:08 | bauzas | gibi: heh, downloading is always greedy | |
| 11:34:28 | bauzas | gibi: but funnily enough, I discovered after 20 ans what IO-bound means | |
| 11:34:34 | bauzas | 20 years* | |
| 11:34:52 | bauzas | now, I'm limited by my clients, not by my bandwidth | |
| 11:35:13 | sean-k-mooney | i used to have semetriic 1gbps but they apparenly only did that for an intoductray trial and dropped my upload to 200mb. i have my home cloud offline for the last while but i was actully ortinnaly more interestedin getting native ipv6 which my current isp does not have an more upload so i could host a few things here | |
| 11:35:47 | bauzas | sean-k-mooney: yeah, I'm lazy with moving to v6 | |
| 11:35:55 | bauzas | while I should | |
| 11:36:12 | bauzas | my ISP is proposing it and I could manage it | |
| 11:36:28 | bauzas | but I'm still concerned by 6to4 | |
| 11:36:34 | sean-k-mooney | i used ot use hricane eltric to provide a tunnel for ipv6 but there latency has gone up recently so removed it about 2 months ago | |
| 11:36:57 | bauzas | that's the whole problem with v6 | |
| 11:37:15 | bauzas | until the whole internet has moved, you'll face problems with 6 :( | |
| 11:37:16 | sean-k-mooney | my isp recentl up there price so im going to move before the end of the year but native ipv6 is on my list of things to look for | |
| 11:37:32 | sean-k-mooney | bauzas: oh we have dual stack connectivity | |
| 11:37:43 | sean-k-mooney | there is no ipv6 only isp in ireland | |
| 11:37:43 | bauzas | hah | |
| 11:38:10 | sean-k-mooney | most are still ipv4 only some offer native ipv6 in addtion | |
| 11:38:16 | gibi | I can write to my m2 ssd with 290MB/s you 1Gpbs download means ~128MB/s writing so a 2.5 Gpbs download would be limited by the local disk receiving the write | |
| 11:38:33 | sean-k-mooney | one even give you native ipv4 and ipv6 without CGNAT on teh ipv4 side but they are $$$$ | |
| 11:39:04 | bauzas | sean-k-mooney: we have one provider that proposes ipv6 native | |
| 11:39:10 | bauzas | but this is an option | |
| 11:39:55 | bauzas | gibi: trust me, I know it ;) | |
| 11:40:11 | bauzas | a classic dd works | |
| 11:40:40 | bauzas | but when it's about collecting pieces from the internet and reassembling them on the fly, I'm | |
| 11:40:52 | bauzas | **really IO-bound, even with 1gbps :) | |
| 11:40:57 | gibi | yeah I can imagine | |
| 11:41:35 | bauzas | yeah, reading newsgroups takes time... :) | |
| 11:42:31 | bauzas | anyway, the dudes probably have stopped to work at the network room | |
| 11:42:32 | sean-k-mooney | god i havent done that in at least a decade. i did for a short while in collage but never found it a good way to consume info | |
| 11:42:47 | bauzas | looks like my gitches are gone | |

| 13:30:19 | gibi | sean-k-mooney: fyi just got reported from downstream https://bugs.launchpad.net/nova/+bug/1942329 | |
| 13:33:48 | sean-k-mooney | gibi: yep this is a know issue | |
| 13:34:12 | gibi | is it an older bug report open for it I should duplicate to? | |
| 13:34:17 | gibi | is there | |
| 13:34:43 | sean-k-mooney | good question tl;dr when drict physical supprot was added they did not add support for any move operations | |
| 13:35:28 | sean-k-mooney | so cold migration resize and shelve are all broken | |
| 13:35:45 | sean-k-mooney | i cant recall if i blocked it for live migration or if that is also affected | |
| 13:36:36 | sean-k-mooney | we have downstream bugs for this https://bugzilla.redhat.com/show_bug.cgi?id=1745842 | |
| 13:37:49 | sean-k-mooney | i dont see an upstream one linked so im not sure if we have an upstream bug but we have talked about it at the ptg before i think | |
| 13:38:58 | gibi | thanks | |
| 13:41:38 | sean-k-mooney | ah yes line 420 https://etherpad.opendev.org/p/nova-xena-ptg | |
| 13:42:08 | opendevreview | Merged openstack/nova stable/victoria: Reproducer unit test for bug 1860312 https://review.opendev.org/c/openstack/nova/+/802842 | |
| 13:42:15 | sean-k-mooney | no upstream links form ath either altough i did not include the downstreeam one so either but lets use your new one for now | |
| 13:44:58 | gibi | ohh cool, I have a very bad memory | |
| 13:45:54 | sean-k-mooney | this has been on my todo list to fix evenuatlly but it keep getting pushed off. artom started fixing some of the degecases and we have resolved other incidnetally. | |
| 13:46:15 | sean-k-mooney | for example live migration did not wrok because 1 the mac was not updated and 2 detach of PF was not implmented | |
| 13:46:29 | sean-k-mooney | gibi: you fixed detach when you added sriov attach/detach supprot | |
| 13:46:37 | gibi | yepp | |
