| cheddacheese | when will ext4 be in the kernel? | 00:22 |
|---|---|---|
| johanbr | cheddacheese: I don't know, but ext4 is still pretty experimental. I wouldn't use it on anything important. | 00:26 |
| cheddacheese | well its in the vanilla kernel. | 00:26 |
| cheddacheese | im using it right now, but its not in the ubuntu kernel | 00:26 |
| johanbr | If it's in the vanilla kernel, I'm sure it'll be synced in for Hardy+1. | 00:30 |
| mjg59 | cheddacheese: There's no guarantee that the on-disk format is stable yet | 00:50 |
| mjg59 | Hence ext4dev rather than ext4 | 00:50 |
| cheddacheese | cant it be included as an expermental option? the user has to add test_fs to there existing ext3 partitions in order to mount as ext4dev. | 00:51 |
| mjg59 | No. There's no reason to be running ext4 now unless you're developing it, and if you are then you'll need to be building new kernels anyway. | 00:52 |
| cheddacheese | o but ubuntu includes xfs which imo is not even stsble as ext4dev | 00:54 |
| mjg59 | xfs has a stable on-disk format | 00:55 |
| cheddacheese | d=the=then y does it corrupt easy then | 00:56 |
| crimsun | where are you getting metrics for "it corrupt[s] easy"? | 00:57 |
| cheddacheese | every hard poweroff corrupts it for me. | 00:57 |
| mjg59 | cheddacheese: That's not what stable on-disk format means | 00:58 |
| cheddacheese | duh | 00:58 |
| mjg59 | When the ext4 format has been stabalised, then it's likely it'll be enabled | 01:00 |
| mjg59 | Until then, it's not useful for it to be | 01:01 |
| cheddacheese | is there a way to enable it without compiling a kernel? | 01:01 |
| mjg59 | No. But, like I said, it's no use as a filesystem right now unless you're willing to back up and restore on every kernel upgrade. | 01:04 |
| mjg59 | So you should only be using it if you're developing the code | 01:04 |
| cheddacheese | im using ext4dev right now as a testfs for some stuff and it has survived more crashes than xfs. | 01:05 |
| cheddacheese | so yeah maybe xfs should be removed until it gets more stablised if it ever does | 01:07 |
| mjg59 | The xfs on-disk format is perfectly stable | 01:10 |
| cheddacheese | maybe for you but not for me | 01:10 |
| mjg59 | No. Really. You don't know what you're talking about. | 01:11 |
| mjg59 | The way in which data is arranged on the disk in xfs does not change with new kernel versions. As a result, new kernels can read partitions formatted with older kernels. | 01:11 |
| mjg59 | That is not currently guaranteed with ext4 | 01:12 |
| cheddacheese | i do know wat i am talking about | 01:15 |
| cheddacheese | when they devoled ext3 they did everything possible not to change the on disk layout to make it backwards compatiable | 01:15 |
| mjg59 | See http://lkml.org/lkml/2006/6/28/454 | 01:17 |
| mjg59 | Note the last paragraph | 01:17 |
| cheddacheese | i see that | 01:21 |
| mjg59 | So, until the on-disk format has been stabalised and will no longer change, it can be enabled in Ubuntu | 01:23 |
| cheddacheese | that wont happen for a long time as most of the stuff that will change the layout r in da mm kernel. | 01:28 |
| mjg59 | That's not a problem | 01:34 |
| cheddacheese | it is for ext3 users | 01:34 |
| mjg59 | Having to backup and restore their filesystems after a kernel upgrade would be more of a problem | 01:35 |
| cheddacheese | im sure you dont know the limitations of ext3 | 01:38 |
| mjg59 | Oddly enough, I do | 01:39 |
| cheddacheese | wat r they den | 01:40 |
| mjg59 | ... | 01:42 |
| cheddacheese | nm | 01:42 |
| mjg59 | (Even if I didn't know, it's hardly difficult to find the ext4 entry on Wikipedia) | 01:44 |
| cheddacheese | I know more about filesystems than any ubuntu kernel dev | 01:56 |
| ripps | I just installed the kernel 2.6.25 using kernelcheck in Ubuntu 8.04. How do I propertly get sound working in the custom kernel? Not having much help in #ubuntu and #alsa. | 04:19 |
| johanbr | ripps: That's hard to summarize in a few lines. You just have to make sure you have all the config options you need and then it should just work. | 04:23 |
| ripps | Do I install Alsa in Kernel, or reinstall the Alsa package? | 04:25 |
| johanbr | In the kernel probably, if you're building a kernel.org kernel. | 04:26 |
| ripps | Another question: Why are custom built kernels so much larger than distrubution kernels? The intrd image was about 45mb, while all the other intrd's were around 8mb | 04:29 |
| crimsun | they aren't stripped. | 04:30 |
| ripps | crimsum: what's that mean? | 04:31 |
| crimsun | and I would build alsa-driver separately unless you enabled all the config options, to which I presume johanbr referred, in your .config. | 04:31 |
| crimsun | ripps: you probably want to see strip(1) | 04:32 |
| ripps | I think the problems I was experiencing was because I accidently built both alsa and oss into the kernel. I'm rebuilding it without oss. | 04:32 |
| crimsun | be aware that 2.6.25 ships with 1.0.16rc2, which is older than what hardy ships in lum. | 04:35 |
| crimsun | (not to mention the various additions and quirks added in lum) | 04:35 |
| johanbr | ripps: Why are you compiling your own kernel anyway> | 04:43 |
| johanbr | ? | 04:43 |
| ripps | johanbr: Just want to play around. Why not? Linux is mostly just my mess around OS anyway. | 04:45 |
| johanbr | okay :) | 04:46 |
| ripps | My system was working TOO well... I didn't have anything to play around with. So I decided to install a new kernel. That would give me something to do. | 04:47 |
| ripps | That's why I'm going to install Intrepid Ibex when it comes to beta | 04:47 |
| johanbr | I thought it was the opposite - that something wasn't working. | 04:48 |
| dacresni | any talk here of porting ksplice to ppc? | 07:10 |
| holinx | hi | 11:22 |
| holinx | Linux 2.6.24-16-generic/i686 is alright for now? | 11:23 |
| holinx | anything i should keep in mind? | 11:23 |
| holinx | or any suggestions | 11:23 |

| tormod | Hi, in dmesg I have Clocksource tsc unstable (delta = -58695238058 ns). Is this bug #221351? There's half(?) minute delay while discovering the boot disk, can this be related? | 20:06 |
| ubotu | Launchpad bug 221351 in linux "TSC Clocksource can cause hangs and time jumps" [Medium,Fix committed] https://launchpad.net/bugs/221351 | 20:06 |
| mjg59 | tormod: No | 20:24 |
| tormod | mjg59: thanks. no on both questions? | 20:26 |
| mjg59 | tormod: No to the latter - it's possible that the message is related to 221351, but it's not causing your boot delay | 20:28 |
| tormod | is the boot delay a known issue? couldn't find a bug report so far. | 20:29 |
| tormod | seems like it's stuck between discovering the disk and discovering the parititions - unless the console messages are buffered - dmesg timestamps don't show much delay. | 20:30 |
| mjg59 | I've seen it, but don't know if a bug is filed | 20:30 |
| mjg59 | I suspect it's hanging during IDE probing | 20:37 |
| mjg59 | Some machines respond very slowly when that's going on | 20:37 |
| tormod | I reported it anyway in bug #223235 | 20:40 |
