| lifeless | cjwatson: So I have a puzzler; grub2 (quantal), 3TB drives, GPT, ef02 + mdraid 1.2 metadata, lvm on that - grub2 doesn't seem to see the md volume (ls doesn't show anything other than (hd*,gpt*) items. | 02:15 |
|---|---|---|
| lifeless | cjwatson: AFAICT it *should* all work, the raid is raid6 left symmetric, the diskfilter,mdraid1x,raid6rec drivers are in the core image. | 02:16 |
| lifeless | cjwatson: I would appreciate some pointers on how to pinpoint why its not working; I don't know if its PEBKAC or a bug - should I file a bug ? | 02:16 |
| Dimensional | hmm | 02:24 |
| Bluefoxicy | I guess Chromium was destroying my drive. | 02:24 |
| Bluefoxicy | iotop said "[jbd2/sdb1-8] was eating 80% of whatever it's measuring | 02:25 |
| Bluefoxicy | while my drive is cranking and cranking loudly by itself | 02:25 |
| Bluefoxicy | so I started killing things until it stopped. | 02:25 |
| Bluefoxicy | This happens sometimes. The system just decides to do something that hammers a spinning drive, with no explanation. :| Don't know if that's a bug or not. | 02:26 |
| lifeless | blktrace will let you track more details about it down | 02:26 |
| Bluefoxicy | ah ok | 02:30 |

| psusi | lifeless, your bios is limited to 32 bit lbas? what does ls -l show the size to be at the grub prompt? | 02:48 |
| lifeless | psusi: BIOS shows 3TB in its config, will check ls -l and report back. | 03:22 |
| === yofel_ is now known as yofel | ||
| lifeless | psusi: 1565563759 sectors | 05:54 |
| lifeless | psusi: at 512 byte sectors I make that to be 746G which is very bogus, and at 4K (the native size), 6TB, which would also be wrong. | 05:56 |
| cjwatson | lifeless: perhaps if you can manage to dump enough bits of the disk that I could reconstruct it in a test environment, then a bug would be handy | 10:09 |
| lifeless | cjwatson: I'll try and trigger it in qemu then | 10:10 |
| cjwatson | you're right that in principle that assembly should work | 10:11 |
| cjwatson | debugging this sort of thing by teleoperation takes eons though :) | 10:13 |
| cjwatson | ideally grub-probe/grub-fstest would reproduce it somehow; if not it would involve an image built with --debug-image=all (or less verbose) and then staring at the output for a while ... | 10:13 |
| lifeless | cjwatson: psusi suggests that the BIOS may be failing to honour > 2TB LBA BIOS int13h (or whatever the interface is these days) calls | 10:15 |
| lifeless | cjwatson: ls -l in a grub image on a usb stick does return an odd sector count - doesn't match disk size for either 512 or 4K sector sizes | 10:16 |
| lifeless | cjwatson: anyhow, I'll fiddle round a few times and see if I can make a reproducable emulated setup | 10:16 |
| lifeless | cjwatson: how does one use grub-fstest | 10:17 |
| cjwatson | it's possible, but the 1.2 mdadm metadata lives at the start of the device ... | 10:18 |
| cjwatson | start with grub-probe, grub-fstest is less interesting most of the time | 10:18 |
| cjwatson | and I can never remember its interface :) | 10:19 |
| lifeless | heh :) | 10:26 |
| lifeless | so grub-probe returns the (AFAIK) correct list of modules - mdraid1x, raid6rec, ext2, diskfilter, part_gpt | 10:26 |
| lifeless | I think it returns lvm too, I can double check | 10:27 |
| lifeless | sudo grub-probe -t abstraction /boot/grub/ | 10:28 |
| lifeless | diskfilter mdraid1x raid6rec lvm | 10:28 |
| lifeless | ext2 from the fs probe | 10:28 |
| cjwatson | which indeed suggests that it's understood the device well enough to parse the fs | 10:30 |
| lifeless | while the array was rebuiling that would fail | 10:30 |
| lifeless | I saw a bug report in debian about that though | 10:30 |
| cjwatson | anyway, sorry, I have to go and do family stuff - like I say if you want me to debug it it's probably better done asynchronously by way of dumps of disk metadata | 10:30 |
| lifeless | yeah | 10:30 |
| lifeless | I'm not sure what disk data you want though. | 10:31 |
| lifeless | e.g. first <x bytes> of the drive + each partition ? | 10:31 |
| cjwatson | where x is say 2^20, yeah | 10:31 |
| cjwatson | that's usually enough | 10:31 |
| lifeless | ok, I'll file a bug and arrange that | 10:31 |
| cjwatson | ta | 10:32 |
| lifeless | hmm, that may pickup some user data too | 10:32 |
| lifeless | I'll make it a private bug i think, though I will eyeball it for personal stuff. | 10:32 |
| cjwatson | well, the md data's fairly close to the start. 64KB is probably enough | 10:32 |
| lifeless | ok; if you need more I can add that later | 10:33 |
| lifeless | I will probably file it tomorrow - thanks for the chat. | 10:34 |
| jtaylor | is it intentional that phonon-backend-gstreamer and libphonon-dev are not coinstallable? | 14:37 |
| jtaylor | seems somewhat weird | 14:37 |
| jtaylor | ok seems intentional phonon-backend-null has Conflicts: phonon-backend | 14:40 |
| jtaylor | weird | 14:40 |
| jtaylor | so how to fix pyside now | 14:40 |
| hyperair | when should an arch: all package be marked as m-a: allowed rather than foreign? | 17:56 |
| JanC | slangasek / wookey / lool : ^^^ sounds like a question one of you can best answer (as you were involved in creating the multiarch spec :) ) | 18:19 |
| shadeslayer | is there a channel for ubuntu touch development? | 19:27 |
| shadeslayer | I keep getting : http://paste.ubuntu.com/5559201/ | 19:30 |
| JanC | shadeslayer: there is #ubuntu-touch & #ubuntu-phone | 19:33 |
| shadeslayer | ack | 19:35 |
| slangasek | hyperair, JanC: when it's a package like 'python', which exists as an abstraction over python2.x which itself provides both architecture-dependent (extensions) and architecture-independent (interpreter) interfaces | 19:51 |
| jbicha | I believe uploads are broken, I mentioned it on #launchpad but it's the weekend and SCALE and everything https://answers.launchpad.net/launchpad/+question/222660 | 22:28 |
| tumbleweed | uploads are overrated :) | 22:29 |
| elmo | jbicha: try now, please? | 22:34 |
| jbicha | elmo: sftp uploads don't seem any different but I think ftp uploads are working now | 22:40 |
