susundberg | uhh, my 3.8.X kernels do not boot, instead they give me kernel panic | 07:25 |
---|---|---|
susundberg | or no panic but stackdump + no boot | 07:25 |
susundberg | Any hints how to get the text that i see on the screen to a file so i can search the issue? | 07:26 |

susundberg | Hi | 12:19 |
susundberg | BluesKaj: can you spare me a moment? My 13.04 kernel 3.8.X is segfaulting on every boot but 3.5.X works fine, i should check what is wrong but taking photo from the display sounds stupid, any suggestions? I have checked kernel.log but its not there (as it hapens on the boot i guess .. ) | 12:24 |
k1l | susundberg: since 13.04 is released you should ask in #ubuntu | 12:25 |
BluesKaj | susundberg, if it's segfaulting then it's difficult to know what's breaking , best to purge the 3.8 kernel and use the 3.5 | 12:28 |
susundberg | k1l: yeah i guess, but the question how to get kernel dump to a text file is not really release related anyhow .. | 12:28 |
susundberg | BluesKaj: thanks | 12:28 |
susundberg | I kind of though to file report but i am not going to take photos of the screen ;) | 12:29 |
k1l | susundberg: so you should prefere the main channel. yes. | 12:29 |
=== ChanServ changed the topic of #ubuntu+1 to: Welcome to #ubuntu+1, the channel for discussion of pre-release versions of Ubuntu. | 13.04 has been released!! http://www.ubuntu.com/getubuntu/releasenotes | https://wiki.ubuntu.com/SaucySalamander/ReleaseSchedule | ||
johnjohn101 | have saucy installed as vmware machine. kernel 3.9 very nice | 15:49 |
johnjohn101 | do you think .10 or .11 will be the released kernel? | 15:56 |
Anca-Emanuel | johnjohn101: 3.10.x look at https://wiki.ubuntu.com/SaucySalamander/ReleaseSchedule Aug 15: 12.04.3 | 16:09 |
lordievader | Good evening. | 18:04 |
bekks | Anca-Emanuel: Where do you see 3.10.x there? | 18:13 |
bekks | The kernel freeze happens on October, 3rd | 18:13 |
Anca-Emanuel | bekks: kernel 3.10 will take at least 60 days to develop. That will be july. | 18:22 |
Anca-Emanuel | bekks: then they need something to deliver for the hardware enablement stack for LTS 12.04.3 | 18:24 |
johnjohn101 | so will 12.04.03 have the 3.10 kernel? | 18:26 |
bekks | Anca-Emanuel: And? 60 days after end of July we will be at 3.11 possible - end of september :) | 18:27 |
alankila | hmm... They aren't supposed to update the kernel version in the stable series? | 18:27 |
bekks | Anca-Emanuel: So its not that clear which kernel version will be used, isnt it? | 18:27 |
alankila | Ah, I see a precise-updates option for a newer kernel than 3.2 | 18:28 |
Anca-Emanuel | johnjojn101: 12.04.1 have 3.5 kernel; 12.04.2 have 3.8 kernel from raring... guess | 18:28 |
johnjohn101 | i have the 3.5 kernel on 12.04.whatever now | 18:28 |
lordievader | Anca-Emanuel: 12.04.2 is already release, should have the 3.5 kernel. | 18:29 |
BluesKaj | for a simple quick check of system activity, ctrl+esc | 18:51 |
johnjohn101 | are we getting gcc 4.8? | 19:09 |
jtaylor | its already in | 19:11 |
johnjohn101 | woot, was going to try to slam it into 12.04 but didn't get around to it, now i have a chance to test!! | 19:13 |
alankila | is there a metapackage for getting all the updated packages at once? | 19:14 |
alankila | for instance the kernel won't update by default, apparently | 19:14 |
vibhav | gcc 4.8 is in | 19:19 |
johnjohn101 | is it bad that when ever i share folders between two ubuntu machines, i use samba to do it? | 19:21 |
alankila | no, I'd use samba in every case. It seems to be the most productized solution. | 19:22 |
alankila | meaning you can basically right click on a folder icon and get it to work, maybe, without having to puzzle out anything much | 19:22 |
alankila | just like windows I guess | 19:22 |
johnjohn101 | yeah, windows solution for ubuntu | 19:22 |
alankila | though some people seem to dislike it when something ordinarily complex becomes rather easy. | 19:23 |
johnjohn101 | doesn't seem right. yeah, i click share on one folder and then use connect to server on another machine and voila, ez file transfer | 19:23 |
johnjohn101 | well it's from the windows world and not the linux world. | 19:24 |
alankila | I had more trouble getting file sharing to work on windows today... mostly because it's a locked down windows machine and the GUI didn't work, but "net use t: \\blahblah\blaa /permsistent:yes /user:blaa" did | 19:24 |
johnjohn101 | i still use net use and my coworkers say i'm too old fashioned | 19:25 |
yofel | alankila: kernel should update automatically as long as you have linux-image-generic installed | 19:27 |
* yofel runs 3.9.0-0 | 19:27 | |
alankila | yofel: it doesn't acquire the precise-update, only new kernels from precise I think... | 19:28 |
yofel | oh, you were talking about precise... | 19:28 |
alankila | Anyway it doesn't actually matter to me in practice | 19:29 |
johnjohn101 | kernel updates seems really only necessary for hardware | 19:31 |
alankila | yeah these are virtual systems | 19:32 |
alankila | I'm keen on getting new kernel versions because I run btrfs. Risky as hell though I haven't lost data yet and I have terabytes on it. but I'm about to start using it on a server with customer data, which means I'm going to do backups extra carefully. | 19:32 |
bjsnider | alankila, as long as you do snapshots and have some unused space and whatnot you're ok | 19:38 |
alankila | yeh that's what I think | 19:39 |
alankila | though I do wonder about my sanity. Still, the experience with btrfs has been positive so far and I've used it on a backups volume due to the snapshot capability for long time | 19:40 |
johnjohn101 | you should post your findings somewhere and share the knowledge | 19:45 |
alankila | long being over a year, but still there's generally some 10 GB of new stuff going in every day and snapshots are kept from days to 1 month with roughly exponential backoff in how the old snapshots get deleted | 19:46 |
alankila | I think you could easily torture btrfs for a few days for similar level of exercise of the filesystem, so my accumulated experience is not very valuable | 19:47 |
alankila | plus properly constructed test would be able to validate that the filesystem has kept the data correctly. | 19:50 |
alankila | the fact I have a backup volume that appears to hold files but which I basically never need means it's not exactly a convincing demonstration of the filesystem's stability. But it has run actual virtual machines for months too and without any issues | 19:51 |
alankila | these virtual machines would crash on data corruption pretty soon | 19:51 |
johnjohn101 | yeah, good luck with all that | 20:02 |
alankila | though only 3.8 kernel provided reasonable performance for VM disk images | 20:02 |
alankila | btrfs is attractive in many ways in that it provides atomic snapshots that allow continued writing ... just such a pain in the ass with the risk that it might crash or corrupt itself somehow | 20:03 |
alankila | the feature set is not bad, and it's right in the kernel, and works with everything. | 20:03 |
alankila | like grub. Better than xfs even. You are always playing with fire if your /boot is on XFS for instance. If you reboot too quick after a new kernel, there's stuff in journal which grub isn't capable of reading | 20:04 |
alankila | and I dare not even try ZFS for the time being | 20:04 |
johnjohn101 | i would love to see an article about zfs on ubuntu | 20:05 |
alankila | The reason why I mention XFS is that it's another serious contender for a VM host because it has supported a version of hole punch ioctl for a long time. It used to be completely XFS-specific but it allows fstrim on guest to free image range on the host side | 20:05 |
johnjohn101 | not even sure what that means. | 20:05 |
alankila | it means VM disk images can be say 100 GB large but only consume like 1 GB of space. If you do a lot of stuff like touch a lot of disk blocks, they grow, even if the real data contained on the guest FS is still 1 GB | 20:07 |
alankila | with support for fstrim and filesystem capable of hole-punching, that space can be freed. | 20:07 |
johnjohn101 | only used when its used | 20:08 |
alankila | I went from 10 GB disk images to 2 GB disk images when I trimmed them | 20:08 |
alankila | for instance loop mount can be performed on the raw disk image and fstrim can be performed on the loop mount nowadays | 20:08 |
alankila | it will be translated by the kernel's loopback mount driver to hole punch ioctls | 20:09 |
alankila | qemu 1.4 users can enjoy ata trim support on the IDE driver | 20:09 |
alankila | enabling the trim was difficult though, because it requires passing a parameter discard_granularity=512 to the IDE device description and libvirt doesn't currently support this parameter, so passing it was difficult. I ended up writing a shell wrapper that notices the -device argument and appends it when ide-disk is being defined | 20:12 |
alankila | it wasn't pretty but whatever | 20:12 |
alankila | annoyingly, the libvirt people even validate that the paramters used in the domain xml specifications can be interpreted correctly by the invoked qemu so they forbid using a comma as value inside. I tried many hacks. For once, someone had engineered this competently. | 20:13 |
alankila | I almost quit using libvirt that day and I keep on thinking maybe I should have thrown it to the river. All it really does is start my VMs at boot and stop them at shutdown. That's not a whole lot of useful work, but I hate writing init.d scripts | 20:14 |
hachre | who is running saucy yet ;D | 20:15 |
johnjohn101 | i have it | 20:17 |
hachre | is it useable? | 20:17 |
hachre | im installing it right now | 20:17 |
johnjohn101 | so far so good. doesn't look like much has changed since 13.04. 3.9 kernel/ gcc 4.8 is all i know about | 20:18 |
Anca-Emanuel | There is any Ubuntu developers here ? Do you plan to support f2fs ? http://ubuntuforums.org/showthread.php?t=2137837&page=2 | 20:18 |
hachre | ya thought so | 20:18 |
johnjohn101 | don't worry, they'll figure out how to break something! | 20:19 |
hachre | Anca-Emanuel: usually if its in debian its gonna be in ubuntu | 20:19 |
hachre | Anca-Emanuel: if you want something in ubuntu the best way is to get it into debian | 20:20 |
johnjohn101 | what file system is that for? | 20:21 |
hachre | new filesystem for smartphone flash the way it looks to me | 20:21 |
johnjohn101 | right for samsung fones | 20:23 |
johnjohn101 | wondering if perl 5.16 will be the default perl | 20:24 |
Anca-Emanuel | johnjohn101: f2fs is for flash based memory devices. Early benchmarks: http://www.phoronix.com/scan.php?page=article&item=linux_f2fs_usb3&num=1 | 20:26 |
jtaylor | isn't that in the kernel? | 20:28 |
jtaylor | or not yet? | 20:28 |
johnjohn101 | http://www.phoronix.com/scan.php?page=news_item&px=MTMxMTU | 20:29 |
johnjohn101 | looks like 3.9 kernel | 20:30 |
jtaylor | then itll be in saucy | 20:30 |
jtaylor | maybe already is | 20:30 |
johnjohn101 | or you have to update kernel in raring | 20:30 |
Anca-Emanuel | jtaylor: what ? f2fs ? yes it is included in kernel, you can read the docs here: https://github.com/torvalds/linux/blob/master/Documentation/filesystems/f2fs.txt | 20:34 |
Anca-Emanuel | hachre: http://cards.linaro.org/browse/CARD-277 sent mail to linaro-dev and Wook Wookey (debian bootstrap expert for arm64) | 21:27 |
