| verwilst | hello, i would like to test a small patch to the kernel that fixes a kernel oops: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1020207/comments/11 but my kernel doesnt seem to build with make-kpkg :( | 09:22 |
|---|---|---|
| ubot2` | Ubuntu bug 1020207 in linux "gfs2 kernel oops when deleting file as first action after mounting" [Medium,Confirmed] | 09:22 |
| verwilst | fsam7400.c:(.text+0x3b0): undefined reference to `populate_rootfs_wait' | 09:22 |
| verwilst | maybe somebody here feels like creating a new kernel deb with this patch that i can test? :) | 09:22 |
| apw | verwilst, i'll have a look in a minutre | 09:22 |
| verwilst | apw, awesome thanks! just gimme a yell | 09:23 |
| apw | verwilst, so is this against precise ? | 09:27 |
| verwilst | yip | 09:27 |
| verwilst | the 12.04 kernel oops'es as soon as you remove a file on gfs2 :) | 09:27 |
| verwilst | it's fixed in 3.3-rc6, which this mini patch is a backport of | 09:27 |
| verwilst | if i can test that this patch works, the redhat guy is willing to give his ACK for -stable inclusion mainline | 09:29 |
| apw | verwilst, whats in the bug is all mangled, and if you want a specific patch included so you can send in a Tested-by it might make sense to email me the patch so i can apply the exact patch | 09:36 |
| apw | verwilst, email in pm | 09:36 |
| apw | verwilst, if there isn't a patch i can make one out of that hunk .... let me know | 09:38 |
| verwilst | apw, well, i just pasted the thing i made :) | 09:39 |
| verwilst | i can mail the patch itself | 09:39 |
| apw | which ever you want | 09:39 |
| verwilst | it's the one in the comments, right? #11, the 4 lines | 09:39 |
| apw | i am assuming thats the one you wanted | 09:39 |
| apw | but it is you who is asking, so i derfer to you :) | 09:40 |
| verwilst | apw, you have mail :) | 09:42 |
| verwilst | it's done in fs/gfs2 btw | 09:43 |
| verwilst | maybe i should have done it from the root | 09:43 |
| apw | verwilst, i'll cope ... which commit in the upstream kernel is this a backport of? am just doing the commentary | 09:47 |
| apw | verwilst, and i am going to take the liberty of adding your signon | 09:47 |
| apw | signoff | 09:47 |
| verwilst | apw, http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=718b97bd6b03445be53098e3c8f896aeebc304aa | 09:48 |
| apw | verwilst, and we don't need the other hunk ? | 09:49 |
| verwilst | apw, normally no, since out_inodes doesnt exist in 3.2 | 09:50 |
| verwilst | apw, https://www.redhat.com/archives/linux-cluster/2012-August/msg00151.html | 09:51 |
| apw | ok. /me shoves it on a buildder | 09:51 |
| apw | verwilst, ok looking at this if we take a previous fixup patch we can take the patch you want unaltered | 10:00 |
| apw | verwilst, so that might be a better solution as the missing error case (which your version doesn't have to fix) looks like something we want to fix also | 10:00 |
| verwilst | the -EROFS? | 10:00 |
| verwilst | that would be VERY nice apw :) | 10:01 |
| verwilst | apw, this patch is actually part of a series with some more handy-looking patches: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=891003abb0db6bfffd61b76ad0ed39bb7c3db8e1 | 10:02 |
| apw | verwilst, ok i'll build a kernel with that as well | 10:02 |
| verwilst | apw, not sure about the possibility to get those in, just wanted to show you as it might make gfs2 a better experience on precise :) | 10:03 |
| apw | hmmm, a tricker proposition if people are not hitting the issue | 10:03 |
| verwilst | the one i pasted is (for now) the only showstopper for me | 10:03 |
| apw | from an SRU perspective | 10:04 |
| verwilst | yeah | 10:04 |
| verwilst | apw, it was just FYI :) | 10:04 |
| apw | verwilst, ok here is the first one: http://people.canonical.com/~apw/lp1020207-precise/ with just your one hunk | 10:13 |
| apw | verwilst, second one with the unaltered patch is building now | 10:14 |
| apw | verwilst, ok they are both there, the earlier timestamp is your patch, the later timestamp is the two cherry-picks ... test them if you could and let me know | 10:30 |
| * apw pokes verwilst | 10:40 | |
| verwilst | apw, i was out for f00d :) | 10:48 |
| verwilst | apw, should i test them both? | 10:49 |
| ogra_ | eat cake then ... | 10:49 |
| apw | verwilst, i would suggest testing the newer one, and if that works we can suggest that to dave woodhouse | 10:49 |
| verwilst | alright great | 10:51 |
| verwilst | so there are more gfs2-related fixes apw? | 10:51 |
| apw | verwilst, this contains just the foundation patch and the full cherrypick of the patch you were porting part of | 10:52 |
| apw | we might also suggest separatly that one at least of the other two you mentioned be pushed to stable, but that is a separate transaction me thinks | 10:52 |
| verwilst | yeah idd | 10:52 |
| verwilst | the gfs2_grow thing for example | 10:53 |
| verwilst | oh well, they all look like nice fixes :) | 10:53 |
| verwilst | apw, with that other patch included, backporting gfs2 fixes should be much more straightforward i guess in the future | 11:01 |

| apw | ppisati, i note they all have massive fans on them, not sure thats the idea :) | 11:27 |
| ogra_ | the v5 system is the management | 11:36 |
| apw | oh thats dumb, so you have to have a different distro on management, awsome | 11:40 |
| ppisati | but those could be candidates for the arm builders | 11:53 |
| verwilst | apw, well, it certainly boots in kvm.. :) | 12:08 |

| verwilst | apw, great success!! | 12:28 |
| apw | verwilst, good news | 12:31 |
| apw | verwilst, so i'll reply to that original thread with the two patches together | 12:31 |
| verwilst | yip | 12:31 |
| verwilst | apw, so, do you decide what goes into the new precise kernel? | 12:32 |
| apw | verwilst, not on my own no, but a bug with a fix is something which is SRUable | 12:32 |
| apw | verwilst, and if it goes into stable then it will hit precise without any action anyhow | 12:33 |
| verwilst | apw, i would certainly think so :) thanks a lot for the help btw! | 12:33 |
| apw | verwilst, np | 12:33 |
| verwilst | apw, will you push it towards stable? | 12:33 |
| apw | verwilst, i think the appropriate thing is for me to add your tested-by (if thats ok) to these two patches and email them as a set in reply to Steven | 12:35 |
| verwilst | okido | 12:35 |
| verwilst | apw, i kinda sent a mail to him as well though, but without the tested-by thing.. feel free to reply and take credit where needed :D | 12:35 |
| verwilst | in all my excitement.. :D | 12:35 |
| verwilst | ( linux cluster ML ) | 12:36 |
| apw | verwilst, heh just want him to know you tested it, so i'd add Tested-by: your email in the bottom | 12:36 |
| verwilst | well, i pointed him to the link you gave me, so if you add it to the patches there... :) | 12:37 |
| rtg | apw, are you guys working on overlayfs ? | 12:38 |
| apw | rtg, i am working on it yes, but not related to this discussion above; crashing heap of junk | 12:38 |
| rtg | apw, ah, bummer | 12:38 |
| verwilst | apw, i'm going to install your kernel on every node of my cluster | 12:39 |
| apw | verwilst, that is the *1111* one that you tested right ... | 12:40 |
| verwilst | Linux vm02-test 3.2.0-31-generic #48~lp1020207v201208221111 SMP Wed Aug 22 10:19:27 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux | 12:40 |
| apw | rtg, i have an id patch accepted, an NFS fix pending, and another i am investigating | 12:40 |
| apw | verwilst, ok i have cleaned up that directory then so only the relevant files are in there, and added the tested-by:, if you want to check its the email you don't mind being in the public record, and if not tell me in PM what you want :) | 12:41 |
| verwilst | it's fine apw :) | 12:42 |
| verwilst | nothing my dspam can't handle ;) | 12:43 |
| apw | verwilst, heh good, as i am not subscribed to that list, i'll let you keep an eye and poke me if i need to do something with those patches, i am hoping Steve will pass them on, if not then i should | 12:50 |
| verwilst | he usually replies pretty quickly | 12:51 |
| verwilst | precise is really starting to get somewhere imo | 12:51 |
| verwilst | 2 months ago i was on the brink of switching everything to centos :) | 12:51 |
| verwilst | because it felt more enterprisy | 12:51 |
| verwilst | every step of the way to a working cluster was riddled with bugs :) | 12:52 |
| verwilst | but now i chased enough people to fix my last hurdle, it's started to look very nice :) | 12:52 |
| verwilst | my faith has been restored | 12:52 |
| verwilst | ;) | 12:52 |
| verwilst | well, 1 hurdle left in lvm2, but hey | 12:53 |
| xnox | verwilst: clvm? | 12:54 |
| verwilst | yip | 12:54 |
| verwilst | the no-monitoring patch thing xnox :) | 12:55 |
| xnox | verwilst: yes. indeed. Do you think we should not have it? TBH I don't know what that monitoring does. | 12:55 |
| verwilst | it works for me now because i manually removed the patch from the deb and recompiled, but hey, it will be a warm fuzzy feeling when it will be really fixed | 12:55 |
| verwilst | xnox, it's only used to build udeb's iirc | 12:56 |
| xnox | verwilst: also in quantal we had clvm init script borked for a little while. Now fixed. | 12:56 |
| verwilst | xnox, because dmeventd isnt running or something similar i think | 12:56 |
| verwilst | xnox, it's the same in debian though | 12:56 |
| verwilst | xnox, ah, is the init script something backportable to precise? | 12:56 |
| xnox | verwilst: it should be applied the whole time, it's just in the running system you can specify monitor=1 or whatever the option is. | 12:57 |
| xnox | verwilst: precise has it. quantal dropped it for couple of months. So if you recompiled from quantal, beware ;-) | 12:57 |
| verwilst | xnox, yeah, but that's the part that's broken :) monitor=xx isnt read anymore | 12:57 |
| xnox | verwilst: ah =) interesting. | 12:57 |
| verwilst | xnox, i think i took it from debian | 12:58 |
| verwilst | the .95 | 12:58 |
| xnox | verwilst: well quantal now has .95 merge with bug-fixes on top of debian. there are a few things different on debian. | 12:58 |
| verwilst | xnox, https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/833368 | 12:58 |
| ubot2` | Ubuntu bug 833368 in resource-agents "clustered lvm commands fail with "activation/monitoring=0 is incompatible with clustered Volume Group" error" [Undecided,In progress] | 12:58 |
| verwilst | xnox, well, it's currently a test setup, i hope to reinstall them once i go production with all the 'native' precise packages :) | 12:59 |
| verwilst | except like libvirt 0.9.13 etc ;) | 12:59 |
| xnox | verwilst: well precise has old lvm2 (missed the feature freeze), so you might have to backport lvm2 from quantal. | 13:00 |
| xnox | verwilst: but I probably should hunt that patch from .96 and apply it in quantal, possibly precise as well. | 13:00 |
| verwilst | xnox, is there a .96? | 13:00 |
| verwilst | ah | 13:01 |
| verwilst | in the bug you mean | 13:01 |
| xnox | yeah. | 13:01 |
| verwilst | bugreport* | 13:01 |
| xnox | from upstream *gasp* | 13:01 |
| verwilst | that would be awesome idd, my coding foo surely isnt strong enough :) | 13:01 |
| verwilst | but for the rest, it's working very well | 13:01 |
| verwilst | now that the gfs2 thing is solved | 13:02 |
| verwilst | i lost many evenings on that problem :P | 13:02 |
| xnox | well, we are here to help ;-) | 13:02 |
| verwilst | xnox, 2.02.95-4ppa1 is my version | 13:02 |
| verwilst | 2.02.95-4 simply recompiled | 13:03 |
| verwilst | what did you 'fix' in the init script? | 13:03 |
| xnox | verwilst: init stayed the same. But for example the debian version is broke some symbols & the multiarch was done fully. Fixed those. | 13:04 |
| xnox | also applied the usual ubuntu patches. | 13:04 |
| xnox | I would recomend you to use $ backportpackage to rebuild quantal's lvm2 for precise into your ppa | 13:04 |
| verwilst | backportpackage? | 13:04 |
| verwilst | ubuntu-dev-tools.. xnox, am i missing out on some good stuff here? :) | 13:05 |
| verwilst | i always do apt-get source, dch -v ... debuild -S -sa; dput | 13:05 |
| verwilst | :) | 13:05 |
| xnox | verwilst: well it does that... automated... and it can also upload it into the ppa for you or build locally =) | 13:06 |
| xnox | verwilst: also it has the handy $ pull-lp-source and $ pull-debian source | 13:07 |
| xnox | verwilst: it takes these arguments: pkgname [exact-package-version | $distro-series] | 13:07 |
| xnox | by default grab latest ;-) | 13:07 |
| verwilst | where has that been all my life! :) | 13:08 |

| * cking notes that clamp looks like it has some powerful grip, ideal for keeping the kids under control ;-) | 17:05 | |
| sconklin | cking: it doesn't actually make contact with the wire under test - it measures the sum of the current passing through the clamp loop. | 17:06 |

| rtg | apw, ^^ | 18:09 |
| jdstrand | smb`: I updated to 3.2.0-30.47-generic in the guest and am running 3.5.0-10.10-generic on the host | 18:09 |
| jdstrand | hmm | 18:09 |
| * apw looks | 18:10 | |
| apw | jdstrand, that was being fixed indeed, i don't think i have seen final resolution on the right fix from upstream | 18:10 |
| jdstrand | apw: I see. so my quantal host doesn't have the necessary bits either? | 18:11 |
| apw | well your precise guest is playing host | 18:11 |
| apw | jdstrand, so i am not 100% sure if that would tickle the same issue or not | 18:12 |
| jdstrand | apw: this is where it gets confusing-- so, I am running an i7 quantal host (my laptop). I start a precise openstack vm. in the precise vm, loading kvm_intel fails | 18:12 |
| jdstrand | $ sudo modprobe kvm_intel | 18:13 |
| jdstrand | FATAL: Error inserting kvm_intel (/lib/modules/3.2.0-30-generic/kernel/arch/x86/kvm/kvm-intel.ko): Operation not supported | 18:13 |
| apw | is there anything at the bottom of dmesg from that invocation ? | 18:14 |
| jdstrand | [ 550.189256] kvm: no hardware support | 18:14 |
| jdstrand | the kvm module is loaded | 18:14 |
| apw | this fix was slated to fix he opposite combination so i am not sure if he would have tested the other way round | 18:15 |
| jdstrand | right | 18:16 |
| apw | so your test isn't going to test the verification requested there | 18:16 |
| apw | though being a valid combination we'd expect it to do something | 18:16 |
| jdstrand | it just happens to be that I upgraded in the meantime and am trying to test an openstack CVE on precise :) | 18:16 |
| jdstrand | apw: the bit I was concerned about was that the linux task was marked "Won't Fix", but this seems very related | 18:17 |
| jdstrand | apw: I'm happy to file another bug, or to comment in the existing one | 18:17 |
| apw | linux should be invalid as in theory invalid as that bug is specific to the other combination | 18:18 |
| apw | i think we should file a new one, as its as likely to be unrelated as not | 18:18 |
| apw | in cause if not symptoms, but do put the new bug number in the old bug | 18:18 |
| jdstrand | apw: interesting. If I do: sudo rmmod kvm_intel ; sudo modprobe kvm_intel nested=1 I get this in dmesg: | 18:19 |
| jdstrand | [ 972.774373] kvm: VM_EXIT_LOAD_IA32_PERF_GLOBAL_CTRL does not work properly. Using workaround | 18:19 |
| apw | jdstrand, you were loading it without nested=1 ? isn't that required ? | 18:19 |
| apw | for your use combination? | 18:20 |
| jdstrand | apw: I was trusting /etc/init/qemu-kvm.conf to dtrt since /etc/default/qemu-kvm has KVM_NESTED=" nested=1" | 18:21 |
| jdstrand | (the default) | 18:21 |
| jdstrand | I just wanted to be *sure* nested=1 was set | 18:21 |
| apw | jdstrand, hmmm ... so i guess can we test nested=1 and see if it makes things work for starters | 18:21 |
| apw | as yeah indeed what you said should be true, but perhaps is not | 18:21 |
| jdstrand | ha! | 18:22 |
| jdstrand | that was it | 18:22 |
| jdstrand | the upstart job isn't working right | 18:22 |
