| Zinn | Bug 728371 in mythbuntu-live-autostart (Ubuntu) "MythTV setup failed with "Cannot login"" [Critical, Confirmed] http://www.launchpad.net/bugs/728371 | 03:06 |
| superm1 | i'm at a bit^D^D^Dmajor loss what's going on. the code for configuring a database hasn't changed in ages, but for some reason it doesn't seem to work anymore. mysql doesn't get spawned in a chroot properly | 03:06 |
| superm1 | all sorts of peculiar errors like non-accessible hardlink creation was attempted by: mysqld (fsuid 102) | 03:07 |
| superm1 | this is the code in particular that's being ran: http://bazaar.launchpad.net/~mythbuntu-dev/mythbuntu/mythbuntu-live-autostart/view/head:/ubiquity/plugins/myth-install-type.py#L147 | 03:08 |

| kees | superm1: sure, in a bit. something funny must be going on. hardlink restrictions were in maverick without this problem hmmm | 03:13 |
| kees | why do people insist on putting things in chroots? | 03:17 |
| kees | superm1: that reconfigure doesn't fail if run manually? | 03:18 |
| kees | oh that's the install chroot. got it | 03:19 |

| superm1 | kees, hmm. could this have something to do with upstart's plans to grow support for chroots in some fashion? | 05:32 |
| superm1 | i'm not sure if that eventually happened | 05:32 |

| kees | superm1: it's really strange regardless. what's the easiest way for me to reproduce the issue locally? | 05:52 |
| superm1 | kees, grab a3 mythbuntu and do an install is the easiest | 05:53 |
| superm1 | i think what's happening is that the upstart managed job from the chroot spits it's /var/run/mysqld/mysql.sock outside the chroot | 05:53 |
| superm1 | so stuff launchedi n the chroot doesn't know about it | 05:53 |
| superm1 | once you've got the install done, you can reproduce at will by running those 3 commands I linked to in succession from cmdline | 05:54 |
| kees | superm1: okay, cool; I'll try it in the morning | 05:59 |
| superm1 | kees, cool thanks. i *think* this diff will fix both problems: http://paste.ubuntu.com/575327/ . but it's probably better to figure out what's really happening that hardlinks are being attempted in the first place for the first problem | 06:04 |

| superm1 | kees, well that patch I proposed last night gets the install all the way through properly consistently, but i think that sysctl thing is a bit hacky, so if you figure out what's going on that the kernel is complaining, lemme know and i'll drop that part | 14:37 |

| Newbuntu81 | anyone have the HVR 2250 working in mythtv with Mythbuntu 10.10? | 17:01 |
| dewman | rhpot1991, I downloaded it from the mythtv wiki, just copied and pasted it into a txt editor. | 17:35 |
| rhpot1991 | dewman: thinking thats your issue, you got bad characters in there | 17:40 |
| rhpot1991 | dewman: use mythwikiscripts to get it | 17:47 |
| dewman | rhpot1991, got it....hehe.. the little things get you.... | 17:48 |
| dewman | rhpot1991, do you know anything about this 6200 script for firewire? | 17:58 |
| dewman | it seems to default to node 1 for what ever reason. | 17:58 |
| rhpot1991 | dewman: check the flags | 17:58 |
| rhpot1991 | you should do it by GUID | 17:58 |
| rhpot1991 | -g I think | 17:58 |

| kees | wowo, I haven't done a myth install in a really long time. the QR code thing is cool :) | 19:23 |
| === superm1` is now known as superm1 | ||
| kees | superm1: so... my install finished without errors. where would I normally see it? | 19:31 |
| superm1 | kees, so check /var/log/syslog | 19:31 |
| superm1 | or if you already rebooted, you'll see that you can't connect to the DB | 19:32 |
| superm1 | in which case, /var/log/installer/syslog is where you would look | 19:32 |
| kees | I haven't rebooted; it's just at the "Restart Now" problem. | 19:32 |
| * kees goes looking around in the install fs | 19:32 | |
| superm1 | you used a3 not today's daily right? | 19:33 |
| kees | ah yeah, there it is in dmesg | 19:33 |
| kees | yeah | 19:33 |
| superm1 | so i believe if you don't reboot, you can also reproduce at will now by just running sudo chroot /target dpkg-reconfigure mysql-server-5.1 or so | 19:33 |
| kees | okay, trying now... | 19:34 |
| kees | it prompts for the mysql root pw... shouldn't that already be preseeded? | 19:34 |
| superm1 | the debconf database is cleared of it at this point | 19:35 |
| superm1 | rerunning dpkg-reconfigure is setting up a "new" password for it | 19:36 |
| kees | this is really weird. | 19:38 |
| kees | in /var/log/syslog I see the rename errors | 19:38 |
| kees | but looking at the files... they're totally fine | 19:38 |
| kees | i.e. owned by mysql:mysql | 19:38 |
| kees | superm1: so, one thing I noticed is that mysqld is running outside the /target chroot | 19:42 |
| superm1 | well is it thougH? | 19:42 |
| kees | yeah /proc/../root points to / | 19:43 |
| superm1 | so how can that happen? | 19:43 |
| superm1 | something to do with upstart's chroot support? | 19:43 |
| * kees suspects upstart silliness | 19:43 | |
| kees | it *still* doesn't explain the hardlink restriction issue, though | 19:44 |
| === toorima_ is now known as toorima | ||
| kees | it's the readlink call that is failing.... wtf | 19:52 |
| kees | superm1: the root cause of the problem is that mysqld is running outside the chroot. does the a3 upstart actually handle chrooted services starting? | 19:56 |
| kees | superm1: because if I kill the running mysqld, dpkg-reconfigure explodes | 19:56 |
| superm1 | kees, yes it does, looks like it got uploaded 4 days ago | 19:56 |
| superm1 | i'm not sure if that's how upstart is supposed to do it, or if that's actually a bug | 19:57 |
| kees | it looks like it's wrong | 19:57 |
| kees | i.e. there is only 1 init running | 19:57 |
| kees | and from inside the chroot, it has no idea about the mysql server | 19:58 |
| kees | *service | 19:58 |
| superm1 | try sudo chroot /target status mysql | 19:58 |
| superm1 | and compare to status mysql (ie outside the chroot) | 19:58 |
| superm1 | upstart knows about the one in the chroot, but not the one outside | 19:58 |
| kees | status: Unknown job: mysql | 19:58 |
| kees | superm1: though this would technically explain the hardlink errors: it's treating the namespaces as separate. i.e. trying to do a link between the outside and inside of a chroot | 19:59 |
| kees | though I haven't proven that yet | 19:59 |
| superm1 | i swear it was the other way around yesterday, and that I could actually run status in the chroot... | 20:00 |
| kees | also, no, I must be wrong about the link errors still. man... I really can't tell where that's coming from. /me studies the strace again | 20:02 |
| kees | there's not a single EPERM in the entire strace. | 20:03 |
| kees | I wonder if it's the mysqld outside the chroot triggering those... | 20:04 |
| superm1 | well i suppose it's a matter of timing - are they showing up before start mysql gets called and it shows up outside the chroot? | 20:05 |
| superm1 | or during the mysqld bootstrap sequence that the postinst runs | 20:05 |
| kees | interesting... it's entirely during "service mysql start" outside the chroot | 20:06 |
| kees | my head is spinning | 20:07 |
| superm1 | glad i'm not the only crazy one here :) | 20:07 |
| kees | okay, so, it seems quite clear to me that upstart is not, actually, doing the right thing with the chroot | 20:08 |
| kees | while /etc/init/mysql.conf.disabled and /target/etc/init/mysql.conf seem to be set up right, mysqld gets started in / not /target | 20:08 |
| superm1 | it shouldn't even be parsing /etc/init/mysql.conf.disabled though should it ? | 20:09 |
| kees | that's why I'm confused. | 20:09 |
| kees | what tells upstart to read /target/etc/init ? | 20:09 |
| superm1 | just grepping the source briefly, i'm only seeing references to an additional stanza in upstart jobs for specifying chroots | 20:14 |
| kees | yeah | 20:29 |
| kees | have you verified that the daily actually ends up with the right password in the users table? | 20:29 |
| kees | I _still_ can't recreate the link error. I've found the place where it's failing (mysqld itself doing a rename) but I don't understand why it fails. doing those actions manually as mysql user succeeds *tear out hair* | 20:30 |
| kees | oh... reproduced it. | 20:33 |
| kees | still horribly confused. :) | 20:33 |
| kees | superm1: I think this might be an aufs bug. http://paste.ubuntu.com/575694/ | 20:48 |
| Zinn | [paste.ubuntu.com] Ubuntu Pastebin | 20:48 |
| superm1 | kees, cool! | 20:55 |
| superm1 | well i'm glad i threw this your way, this is far lower level than i was about to investigate | 20:55 |
| kees | superm1: yeah, now that I can reproduce it, I'll dig further. | 20:56 |
| kees | superm1: I worry that the yama-disable work-around just papers over the real problem: mysql is running in /var/lib/mysql instead of /target/var/lib/mysql. | 20:56 |
| kees | superm1: but I'll continue to work on this yama-vs-aufs bug | 20:57 |
| superm1 | at least for the purposes of setting up mysql in the chroot, it's actually an N/A | 20:57 |
| superm1 | because mysql just gets started at the "end" of the postinst so it's ready to go | 20:57 |
| superm1 | so it won't cause any problems on the end system (as long as it's manually respawned in the chroot) | 20:58 |
| kees | ah. I was worried that the preseeded passwords wouldn't make it into the final /target filesystem | 20:58 |
| superm1 | i *think* they will | 20:58 |
| superm1 | i'll double check | 20:58 |
| kees | let me open a bug in LP for the yama-vs-aufs, and can you add a link to it in the code where you disable yama during the install? should be easy to track for removal when it's fixed at some point. | 20:59 |
| superm1 | yes, that'd be great | 20:59 |
| kees | one, sec sec | 20:59 |
| kees | superm1: okay, it's bug 729338 | 21:06 |
