svenl | hi guys ... | 05:48 |
svenl | is it true that you guys dropped the mkvmlinuz support for the dapper linux-image kernel ? | 05:49 |
svenl | i heard a report claiming it was because "nobody uses oldworld machines anymore", which seems likevery clueless ... | 05:49 |
=== mroth [n=mroth@unaffiliated/mroth] has joined #ubuntu-kernel | ||
mjg59 | We've never supported oldworld machines | 05:55 |
mkrufky | what is 'oldworld' ? | 05:55 |
mjg59 | mkrufky: Pre-imac and blue and white G3s | 05:55 |
mjg59 | When those were introduced, Apple went to a new Open Firmware version | 05:58 |
mjg59 | So the ended up being called "old world" and "new world" macs | 05:58 |
svenl | mjg59: yeah, but the mkvmlinuz support patch was not there for oldworld, but for chrp machines, including IBM chrp and genesis's pegasos machine. | 05:58 |
mkrufky | ah, okay | 05:58 |
svenl | mjg59: and genesis was just added recently as a ubuntu partner, so i doubt that sabotaging the pegasos support this way is the right thing to do. | 05:59 |
mjg59 | svenl: If you are going to describe it as "sabotaging", then this conversation is over | 05:59 |
svenl | mjg59: well. | 05:59 |

svenl | mjg59: oh well, i will let my hierarchy handle this with the ubuntu hierarchy, but this is a repeat of what happened for the breezy release, so i am not overly sympathetic, especially since the ubuntu kernel guys are making noises about unification of the ubuntu kernel with the debian kernel on public forums and such. | 06:01 |

fabbione | uh?= | 06:16 |
fabbione | what noise? | 06:16 |
fabbione | when? | 06:16 |
fabbione | wth is he talking about? | 06:17 |
mjg59 | No idea | 06:18 |
fabbione | neither do i | 06:18 |
dilinger | sorry guys, that was probably my fault | 06:20 |
mjg59 | I don't think Sven can ever be anyone else's fault | 06:20 |
dilinger | the fact that he's re-evaluating ubuntu-kernel, that is | 06:21 |
dilinger | heh | 06:21 |
mjg59 | Have you kicked him off debian-kernel yet? | 06:21 |
dilinger | no, i just angered him. i intend to get him ejected from the project completely. | 06:22 |
fabbione | dilinger: LOL | 06:22 |
dilinger | fabbione: btw, you have any pointers to architecture/design of ocfs2? | 06:27 |
fabbione | dilinger: the code? | 06:27 |
fabbione | it's the "usual" clustered FS | 06:28 |
fabbione | all transactions needs to go trough the DLM | 06:28 |
fabbione | it's journaled like ext3 (same backend) | 06:28 |
dilinger | fabbione: a coworker's evaluating cluster filesystems (pvfs2, gfs, ocfs2, etc).. i had was hoping for something to pass along for him to read | 06:29 |
dilinger | since he can't seem to find details about ocfs2 | 06:29 |
fabbione | dilinger: you can check on oss.oracle.com | 06:29 |
fabbione | the project is hosted there | 06:29 |
fabbione | but the concept behind each clusterFS is the same | 06:29 |
fabbione | and that's where the real power of FS comes frok | 06:30 |
fabbione | from | 06:30 |
fabbione | the Distributed Lock Manager | 06:30 |
fabbione | performance of the FS are highly dependent on that | 06:30 |
fabbione | also.. ocfs2 is the simplest one around.. at least that i have seen | 06:31 |
fabbione | it's really basic clustering | 06:31 |
fabbione | a more complete suite is the GFS/RH cluster | 06:31 |
dilinger | fabbione: simplest in terms of implementation? features? | 06:33 |
fabbione | features | 06:34 |
fabbione | in my experience: | 06:35 |
fabbione | - ocfs2 is faster, but needs more manual tuning to handle the timeouts between nodes properly. It does "only" cluster FS | 06:35 |
fabbione | - gfs/rh cluster suire is generally slower, no need of manual tuning, it offers a complete suite for clustering, from shared IP, switching services, etc. | 06:36 |
dilinger | ok, thanks | 06:49 |
BenC | damn, I missed sven and his FUD | 06:53 |

torkel | dilinger: Lustre might be interesting for him to take a look at too; http://www.clusterfs.com/ | 08:10 |
dilinger | yep | 08:12 |
dilinger | i've been following lustre development ever since the clusterfs people abandonded intermezzo | 08:12 |
torkel | would be nice to see it in Ubuntu :-) | 08:13 |
dilinger | yea | 08:13 |
dilinger | i was going to package it for debian ages ago | 08:13 |
dilinger | but decided not to based on their release policy | 08:13 |
dilinger | they've changed it since, but i haven't had time to look at it again | 08:14 |
dilinger | i may still package it | 08:14 |
dilinger | i think mrvn took over my ITP | 08:14 |
torkel | a co-worker did a quick-a-dirty package of it last week | 08:14 |
torkel | not sure how far he got though | 08:14 |
dilinger | i'd be interested in seeing it | 08:15 |
dilinger | like i said, my coworker's evaluating different cluster filesystems; if we decide to go w/ lustre, i'll probably end up maintaining packages | 08:15 |
dilinger | quick-and-dirty packages makes it that much easier for him to try out | 08:15 |
torkel | he is on vacation this week, but if you send me a mail (otherwise I will forget it) I can ask him to get in touch with you | 08:17 |

jbailey | BenC: Are you packaging newer kernels at all for testing? | 08:39 |
jbailey | I thought I saw some reports of some threading stuff fixed in newer kernels. If you've already got a set built, I might poke my head into them. | 08:40 |
jbailey | threading and signals. | 08:40 |
BenC | jbailey: haven't had a chance to start merging to newer kernels yet | 08:40 |
jbailey | No worries. I'll try to remember how to build one myself for the test. | 08:40 |
jbailey | None of it's a regression from previous, but on some arches there are weird nptl responses and such. | 08:41 |
fabbione | jbailey: jumping from .15 to .16 is a big step due to all the mutex changes | 08:41 |
fabbione | merging back is difficul | 08:42 |
fabbione | +t | 08:42 |
jbailey | fabbione: Right, I'm not expecting to backport anything, more just curious if these are the problems refered to. | 08:42 |
jbailey | fabbione: I'm trying to figure out what the path to actually getting clean glibc results is. | 08:42 |
