[13:05] utlemmin`, Odd_Bloke: do you look after the Docker image that ends up being fetched as "ubuntu:trusty" by users? [13:05] See bug 1505164 [13:05] bug 1505164 in python3.4 (Ubuntu) "python3.4 3.4.3 prevents installation of libapache2-mod-wsgi-py3" [Undecided,Invalid] https://launchpad.net/bugs/1505164 === utlemmin` is now known as utlemming_sprint [13:21] rbasak: looking [13:22] rbasak: this looks concerning [13:24] utlemming_sprint: I'm pretty baffled as to how that could happen by accident. [13:25] rbasak: well, the bug is wrong...because I can't repo it [13:25] rbasak: the versions are there but apache installs correctly [13:25] utlemming_sprint: yes, apache does install correclty [13:25] utlemming_sprint: a subseqent install of libapache2-mod-wsgi-py3 fails though as described [13:25] rbasak: I think that the likely story is out of date apt cache [13:25] utlemming_sprint: it's not that the apt cache is out of date [13:26] utlemming_sprint: it is that the docker image ships a package from trusty-proposed without trusty-proposed in sources.list. [13:26] utlemming_sprint: (and it shouldn't have a package from trusty-proposed anyway) [13:26] rbasak: I'm checking how docker does their builds [13:27] utlemming_sprint: is it something you deliver? Or not in our (Ubuntu) hands? [13:27] rbasak: we deliver the base image and then they do somethings to it [13:27] I see, OK [13:27] rbasak: they as in docker [13:28] So I guess the question is whether the base image includes Python from trusty-proposed or trusty-proposed in sources.list. [13:28] rbasak: so the image that we delivered to Docker has 3.4.0-2ubuntu1.1 [13:28] utlemming_sprint: OK, so it sounds like they're doing something broken [13:28] utlemming_sprint: I'll ask kirkland to pass to Docker upstream. [13:28] utlemming_sprint: thanks [13:29] rbasak: that is my $0.02. the cloud image team does have relationships with the docker guys [13:29] rbasak: I had lunch with them on Thursday last, incidently. [13:39] rbasak: utlemming_sprint: I think this is caused by the Python 3.4.3 release to and subsequent removal from the trusty archive. [13:39] rbasak: utlemming_sprint: So this isn't to do with -proposed ending up on the image, it's just the image being created in that window of failure. [13:39] Odd_Bloke: you're right [13:40] So I'll orchestrate getting a new image out, but we know the root cause. :) [13:40] Odd_Bloke: See https://partner-images.canonical.com/core/trusty/20151001/ubuntu-trusty-core-cloudimg-amd64.manifest (which matches the docker image) and https://partner-images.canonical.com/core/trusty/20151009/ubuntu-trusty-core-cloudimg-amd64.manifest which is the latest [13:42] Odd_Bloke: whoa. We did that? I'm surprised it was pulled in that way instead of putting a reverted higher version in trusty-updates. Thanks. [13:42] Odd_Bloke: do you have a bug number handy? [13:42] https://bugs.launchpad.net/ubuntu/+source/python3.4/+bug/1500768 is the regression bug [13:42] Launchpad bug 1500768 in python3.4 (Ubuntu Trusty) "python3.4.3 SRU break requests" [High,Triaged] === rattking_ is now known as rattking [14:58] i need always type: sudo route add default gw 192.168.0.1 but wich fileneed modify for make it permanently? [15:00] jak2000: I guess this is for a static ip? Add it to /etc/network/interfaces. [15:01] lordievader: http://pastie.org/10476820 [15:02] jak2000: Exactly, there is no gateway defined. [15:03] yes [15:03] how to define? [15:03] gateway 192.x.x.x [15:03] ? [15:05] done [15:06] after 2,3 minutes my ubuntu server sleep, how to fix it? i dont want sleep, any advice? [15:36] lordievader? [15:38] jak2000: gateway 192.168.0.1 perhaps [15:39] done [15:40] RoyK i have installed ubuntu 14.04 basic, no gui installed but why sleep after 2-3 minutes i think is a full sleep bbecause not answer hte ping [15:40] no idea - try a reboot to see if the gateway is right [15:43] ok === markthomas|away is now known as markthomas === Lcawte|Away is now known as Lcawte [17:12] jak2000: You could easily find this out yourself: https://help.ubuntu.com/lts/serverguide/network-configuration.html#ip-addressing [17:26] how to connect USB Modem to enable internet on ubuntu 14.04 server?

Many helpers are in more than one channel and it's not fair to them or the other people seeking support. [17:51] teward, I didn't really want to. I am using well community supported ubuntu with big hope from community [17:55] linocisco: you still shouldn't crosspost. [17:57] teward, I will use centos .bye ubuntu server [17:58] I guess that is one way to deal with your problems... [17:58] my guess from them in #ubuntu they're already using centos === adam_g` is now known as adam_g === ksx4system is now known as Guest67778 [19:21] good evening everyone [19:21] I am havining a little delima with rsyslog, would i be able to get assistance here?

If anyone knows the answer they will most likely reply. :-) See also !patience === quantic is now known as Guest66928 === quantic_ is now known as quantic === Guest67778 is now known as ksx4system [19:28] ok, i am trying to use rsyslog from my cisco device (192.168.1.49) and my rsyslog (192.168.1.46). I followed this tut: http://tinyurl.com/npgx6r8. I don't see anything being recorded inside my log file /var/log/cisco/cisco.log. however, i see traffic generated from my cisco device using tcpdump, and it is getting to the right port as well! http://pastebin.com/kxacY5Fk. What am i missing or doing [19:28] wrong. TIA [19:48] jamespage, neutron 7.0.0~rc2-0ubuntu2 uploaded [19:49] jamespage, that should fix some dep 8 issues [19:55] nm i figured out what was my problem . thank you all [20:42] dannf: ok, i put a first merge attempt of debian's 2.4 qemu to https://launchpad.net/~serge-hallyn/+archive/ubuntu/qemu-vgicv3 . i have not yet added your patch, will do that tonight or in the morning if htis merge doesn't bom [20:42] bomb [20:42] which i somewhat expect it will [20:43] for now, i've worked more tha the half day i was planning, so /me out [20:43] hallyn: fair enough - thanks! [21:46] smoser, utlemming_sprint : if two bootable volumes are presented to a kvm (openstack) vm, shouldn't the instance still boot from vda (instead of vdb)? And I'm guessing cloud-init isn't remotely involved in this, so not sure why I"m asking you two. More of a kvm or nova issue. [21:46] * med_ was clearly thinking out loud ^ === Lcawte is now known as Lcawte|Away [23:19] hi there :) [23:21] i've running 14.04.3 lts on a 64gb emmc. Server purpose would be a webserver for a groupware installation for 5-10 users (apache2, mysql, php, postfix, dovecot) and i've also was planning to add a nagios instance sometime later... any purposes concerning the partitioning scheme? [23:23] i thought to add at least separate partitions for /home /mail /var /tmp but im quite unsure 'bout the sizes [23:26] also thought about to move the /var and /mail partitions to an external usb3 hdd to avoid the wearing of the emmc but i've no experiences concerning the performance [23:27] /tmp should probably be a tmpfs (which is the default IIRC) [23:28] yeah it's default [23:29] not surewhy you need /mail [23:30] or even why you need partitions :) [23:31] or at least, why you need multiple "user partitions " [23:31] just put everything on /home or /srv [23:33] primary for security reasons and to avoid a total system crash if for example a deamon is running mad and fill up the partition with trash [23:34] IPU: System shouldn't crash, that's what the reserved blocks are for [23:35] jpds_: well, unless daemons run as root, I guess ;) [23:36] but, I think logs & mysql databases would be the only likely culprits for that [23:37] and it's possible to put user databases and user logs in their respective (virtual) home directories [23:37] i've often seen systems getting unaccsesible cause the entire diskspace is eaten up during malfunction or let's say during an attack [23:38] IPU: Just reading the first paragraph of http://www.howtogeek.com/196541/emmc-vs.-ssd-not-all-solid-state-storage-is-equal/ would make me not put that on a server [23:39] jpds_: you probably also wouldn't use a USB3 HDD on a server :) [23:39] JanC: I wouldn't, no [23:42] IPU: Also, I wouldn't cramp so much stuff on the same box but that could just be me [23:42] jpds_: For example, the SSD controller spreads read and write operations over all the memory chips in the solid-state drive [23:42] erm [23:42] you don't spread reads - only writes [23:43] so, it would be be useful to know if this is a company thing or some family/student thing :) [23:44] RoyK: some expensive SSD might do internal RAID where spreading READs would be useful, but yeah :) [23:44] jpds: uhm... i don't know what kind of emmc's you know but in my system i made with a class 10 sd 'bout 8,5MB/s write and 18,9Mb/s read... my emmc makes 39.3mb/s write and 140mb/s read [23:45] some *very* expensive SSDs [23:45] IPU: My SSD does 550MB/s read, 500MB/s write [23:46] eMMCs could be nice for tiering, though [23:46] if there was an open source tiering solution out there [23:47] Like, bcache? [23:47] no, like btier [23:47] tiering isn't caching [23:47] jpds_: i would also take a ssd instead if i would have the appropriate interfaces for it ^^ [23:48] so, this really sounds like a home thing, right? [23:48] jpds_: but the hardware on which i plan this server has only sd and emmc ;-) [23:48] it's more like a test for a very small and low power consuming system [23:49] http://www.hardkernel.com/main/main.php [23:49] tiering is keeping cold data on slow storage - caching is just keeping hot data temporarily duplicated on fast storage, it's not moving things around according to use [23:49] for those who know [23:51] RoyK: what's the benefits? [23:52] JanC: well, if you have, say, 10TB of data, usually 10% or perhaps 20% of the data is "hot", so you want to store that on fast storage, like a raid-1+0 on fast disks or SSDs and the rest on slower storage, say 7k2 drives in raid-6 [23:52] JanC: with multiple tiers, that can be very beneficial [23:53] JanC: uio.no has 10PiB or so ranging from SSDs for the hottest part to tape (40%) for anything not used the last 6 months or so [23:53] but what's the benefit over caching? [23:54] caching won't last over a reboot [23:54] tiering is in the storage itself [23:54] that depends on how you cache [23:54] and caching is just duplicating things, not moving the data to faster tiers [23:54] lots of caches persist over reboot [23:55] caching is caching, it's not tierd storage [23:55] well, you copy them to faster tiers [23:55] instead of moving [23:55] wich should be faster actually ;) [23:56] but then, say, you have a tier 1, ssd on pcie, tier 2, ssd on sata, tier 3, 10k sas drives, tier 4, 7k2 drives, tier 5, tape [23:56] hitachi makes those things [23:56] and they really work well [23:56] cern is also using a tiering system [23:56] costs a lot, but then, if you need a bunch of petas, that costs a bit [23:57] IPU: any idea what sort of storage system they use? [23:57] IPU: CERN's "tiering system" is a caching system [23:58] they don't delete data from their tapes when they copy them to HDD or SSD [23:59] I'm pretty sure Hitachi's "tiering" system actually is a caching system [23:59] http://home.web.cern.ch/about/computing/grid-system-tiers [23:59] JanC: deleting data from tape takes a while and if the data isn't modified on the upper tier, it makes no sense to remove it from tape [23:59] it would be silly to do otherwise [23:59] RoyK: so then they just "cache" [23:59] mostly [23:59] JanC: but it makes sense to *move* data from lower tiers like 7k2 drives to 10k/15k to ssds
