| brendand | infinity, is it just me or are a lot of the kernels seriously overshooting their verification phase? | 08:57 |

| brendand | apw, smb ^ (or anyone in this timezone that knows what is going on)? | 08:59 |
| infinity | brendand: I think Brad's been chasing people down to get the last few bugs verified. | 09:00 |
| infinity | brendand: You can check progress at http://status.qa.ubuntu.com/reports/kernel-bugs/reports/sru-report.html | 09:01 |
| brendand | infinity, am :) | 09:01 |
| apw | brendand, heh no sorry, been on vacation for a couple of days :) | 09:03 |
| infinity | brendand: I don't think it'll hurt anyone's feelings if you start doing cert testing on them before the bot has flipped the tasks. | 09:04 |
| * infinity goes to find a bed. | 09:05 | |
| apw | arges, yo ... how is the crash testing going ... | 09:07 |
| hallyn_ | apw: hey, so if I do mkdir a; subvolume create a/b; echo c > a/b/c; rsync -va --one-file-system a b | 12:34 |
| hallyn_ | apw: then b/b is empty. I.e. a subvolume is treated as a separate filesystem | 12:34 |
| hallyn_ | apw: is that the expected behavior? | 12:35 |
| apw | what the heck is a subvolume | 12:35 |
| apw | subvolume | 12:35 |
| apw | subvolume: command not found | 12:35 |
| apw | i don't even get an offer of one | 12:35 |
| hallyn_ | apw: make that 'btrfs subvolume' | 12:35 |
| apw | i think i would expect a subvolume to be a mount, does it appear as a mount ? | 12:36 |
| hallyn_ | no | 12:36 |
| apw | in /proc/mounts i mean | 12:36 |
| hallyn_ | it only shows up in 'btrfs subvolume list' | 12:36 |
| apw | hallyn_, so rsync figures it out from the stat 'st_dev' field for the file | 12:38 |
| apw | hallyn_, so if files in a subvolume have a different st_dev then it will think they are a filesystem | 12:38 |
| * henrix -> lunch | 12:41 | |
| hallyn_ | apw: i'm surprised it has a different st_dev. will ahve to think about what to do about that... | 12:42 |
| apw | hallyn_, don't subvolumes represent things like snapshots, i would think they would have to have a different st_dev to avoid being the same actual file in rsync's mind | 12:43 |
| === mdeslaur_ is now known as mdeslaur | ||
| hallyn_ | apw: yeah they can represent snapshots. but the first one you create (which you can then snapshot) also shows up a different fs. which in one way makes sense, but otoh if it doesn't show up in /proc/mounts i'm not sure how a backup script shoudl know whether to separately rsync /var/lib/lxc/$container/rootfs, which may or may not be a subvolume | 12:50 |
| hallyn_ | i mean, yeah, i can call out to btrfs subvolume, but if i have to do separate tricks for each fs, that's kind of pathetic | 12:51 |
| apw | yeah doesn't make much sense does it | 12:51 |
| hallyn_ | apw: but anyway, thanks - so that's an answer for lifeless_ at least :) it *is* a different fs, you just have to do it separately | 12:52 |
| apw | at least in rsync's mind indeed | 12:52 |
| hallyn_ | thanks | 12:53 |

| bjf | brendand, feel free to start testing i have no reason to believe there will be a respin of any kernels at this point (hopfully i didn't just jinx myself) | 14:17 |
| brendand | bjf, that's what i was wondering | 14:18 |
| brendand | bjf, it's not a huge problem if there is - but better to know that it's unlikely | 14:18 |
| brendand | bjf, i noted though that there is no lucid kernel. have they stopped completely now? | 14:19 |
| bjf | brendand, no, just no patches this cycle | 14:19 |
| brendand | bjf, ok | 14:19 |
| bjf | brendand, though we expect fewer and fewer at this point | 14:19 |
| rtg | kees, I'm repackaging rng-tools for v4 'cause debian is way behind and the maintainer is unresponsive. You added TPM cruft in 2009. Is it still necessary ? See kernel.ubuntu.com/~rtg/rng-tools-4 for the new source package. | 14:23 |

| rtg | apw, why is kernel promotion getting held up by an eglibc autopackage test ? what is it doing ? | 15:21 |
| jdstrand | apw: hey, I think bug #1204005 may be fixed in 3.11 | 15:25 |
| ubot2` | Launchpad bug 1204005 in linux (Ubuntu Saucy) "[saucy] kvm host hangs of guest boot with 3.10.0-5" [Critical,Triaged] https://launchpad.net/bugs/1204005 | 15:25 |
| jdstrand | apw: I was able to boot saucy and raring vms, both with vmvga, login to a unity session, launch a browser, etc | 15:27 |
| apw | jdstrand, yay thank $deity for that, that was my percieved experience as well | 15:36 |
| apw | rtg, i believe it is a functionality test, and all 'depends' packages have their tests run | 15:36 |
| apw | rtg, so in this case eglibc needs kernel headers so it is tied to the kernel | 15:36 |
| apw | rtg, howerver i think the eglibs tests generally are not very good and run out of space | 15:37 |
| rtg | apw, wll its pissing me off. IOError: [Errno 28] No space left on device: '/home/ubuntu/adt-log//dsc0-build-xerr' | 15:37 |
| apw | rtg, yeah that sucks, so i bring those up on #ubuntu-release and whine | 15:37 |
| ogra_ | ship a usb key in your source package :) | 15:37 |
| rtg | apw, already did, but I think most everyone is at debconf | 15:37 |
| apw | ahh no so good, i think jibel is responsible for that puppy | 15:38 |
| rtg | apw, http://kernel.ubuntu.com/~rtg/rng-tools-4 | 15:44 |
| apw | rtg, so i think if the upstream version is '4' this should be versioned as 4-0ub | 15:49 |
| apw | rtg, so i think if the upstream version is '4' this should be versioned as 4-0ubuntu1 | 15:49 |
| apw | as logically the first debian version would be 4-1 | 15:49 |
| rtg | apw, I thought about that, but none of Jeff's versions in the past have had a minor number | 15:49 |
| apw | 42-unofficial-mt.14-1ubuntu1 | 15:49 |
| apw | rtg, that is *-1ubuntu1 | 15:50 |
| apw | rng-tools (2-unofficial-mt.14-1) unstable; urgency=low | 15:50 |
| apw | was the debian version there | 15:50 |
| rtg | apw, ok, I'll add the minor number | 15:50 |
| apw | rtg, that is *-1ubuntu1 unclear how 4-unoffical-m...1 would sort relative to 4-0u1 | 15:50 |
| rtg | apw, seems like the other version cruft is just BS | 15:51 |
| apw | rtg, and with it there sorting is all a bit of a lottery anyhow | 15:52 |
| apw | rtg, but i think 4-0ubuntu1 seems appropriate | 15:57 |
| * apw idly wonders who maintains it in debian, as it clearly has not been maintained for some time | 15:58 | |
| rtg | apw, ok, updated the version. I'm inclined to just upload it. | 16:11 |
| apw | rtg, yeah the binaries look similar to the previous version | 16:12 |
| apw | rtg, there are some very minor lintian errors, nothing to hold you up | 16:12 |
| rtg | apw, right. the big difference is that I ripped out some TPM cruft from kees. we can always add it back if need be | 16:12 |
| rtg | apw, I might drop this on the c-k-t PPA first to make sure armhf builds | 16:13 |
| apw | rtg, good plan, my amrhf builder isn't booting right now ... grrr | 16:14 |
| bjf | brendand, seems i might have jinx'd myself .. looking like we may have to respin Q and R (still investigating) | 16:14 |
| rtg | apw, I don't have an armhf sbuilder right now either | 16:14 |
| * apw goes and tries again | 16:15 | |
| brendand | bjf, lol - i don't think we've started testing anyway :) | 16:15 |
| bjf | brendand, indeed, it looks like i'm respinning. you should have new kernels tomorrow. if we have to delay the start of the next cycle, that's just how it goes. | 16:26 |
| kees | rtg: hrm, I added TPM cruft? | 16:33 |
| kees | rtg: oh, the rng-tools? hey, don't rip that out, I use it! | 16:33 |
| rtg | kees, maybe you could get garzik to add it to his upstream repo ? | 16:34 |
| kees | it's been semi-abandoned by debian, though. :( | 16:34 |
| kees | yeah, I'll ping him | 16:34 |
| kees | oh, hm, there's a note about doing this in the kernel... | 16:35 |
| kees | hmm 578b016fdc91464c08c096f0c5952cae549fdb8f | 16:36 |
| rtg | kees, otp, I'll be back i a bit | 16:37 |
| kees | went into 3.7, so I guess I'll just switch what I'm doing. | 16:37 |
| kees | $ grep HW_RANDOM_TPM /boot/config-3.8.0-27-generic | 16:38 |

| kees | ogra_: what? | 16:43 |
| ogra_ | then you wont need theft protection ;) | 16:43 |
| ogra_ | (isnt that what TPM is ?) | 16:43 |
| kees | is that what "tpm" means to you? :P | 16:43 |

| === fmasi is now known as fmasi_afk | ||
| === lifeless_ is now known as lifeless | ||
| lifeless | hallyn_: so this comes back to my question; can we disable the lxc btrfs integration ? | 19:53 |
| hallyn_ | lifeless: yes, we can. question is only how shoudl we? | 19:55 |
| hallyn_ | lifeless: i think in the past i required /var/lib/lxc to be its own btrfs mount to do the integration. but i don't think that's compelling. | 19:56 |
| hallyn_ | lifeless: are you sure you'll never wnat to lxc-clone? is updating the backup scripts more palatable by any chance? | 19:57 |
| lifeless | hallyn_: how about a flag on lxc-create and lxc-clone | 19:58 |
| hallyn_ | lemme try something | 19:58 |
| lifeless | hallyn_: to disable both lvm and btfs special behaviours | 19:58 |
| hallyn_ | lifeless: what is the lvm special behavior? | 20:00 |
| hallyn_ | lifeless: if you do 'lxc-create <...> -B dir', does it then not create a subvolume? (was going to test myself, but my box is busy installing a bunch of fresh containers so i'm stuck on a lock) | 20:00 |
| lifeless | hallyn_: man lxc-clone says When the original container's | 20:04 |
| lifeless | rootfs is an LVM block device or is on a btrfs filesystem, then a snapshotted clone can be created, | 20:04 |
| lifeless | taking up very little initial disk space. | 20:04 |
| hallyn_ | yes | 20:09 |
| hallyn_ | but you have to ask for an lvm backed container to get one. it's a separate block device. not really analogous to the btrfs case | 20:09 |
| lifeless | hallyn_: sure | 20:22 |
| lifeless | hallyn_: so I guess I'm saying | 20:22 |
| lifeless | hallyn_: lets make lxc behaviour predictable. Ask for LVM -> Ask for btrfs. | 20:22 |
| hallyn_ | lifeless: iiii... still prefer to default to a subvolume, but i might be wrong. | 20:27 |
| hallyn_ | still waiting to be able to test lxc-create -B dir in btrfs | 20:27 |
| lifeless | hallyn_: so -B means I'd need to put in /var/lib/lxc/foo/rootfs for each invocation? I presume you just want to test the code paths ? | 20:28 |
| lifeless | hallyn_: So if btrfs is on by default, I'd be happy if there is an option to turn it off for both create & clone | 20:29 |
| hallyn_ | lifeless: no, -B would just mean | 20:29 |
| hallyn_ | lxc-create -t ubuntu -B dir -n x1 | 20:30 |
| lifeless | oh, -B none - gotchya | 20:30 |
| lifeless | blah, dir. I see. | 20:30 |
