| arossDOTme | I thought a prev sdcard was formatted with ext4 with disable journalling and my NN could read it. Reforted a new sd card as ext4, no journal. NN won't mount it and e2fsck on the nano note complains about the super block. What do I need to do differently? | 00:22 |
|---|---|---|
| wpwrak | arossDOTme: a general check: is ext4 in /proc/filesystems (on your ben) | 01:07 |
| pabs3 | wpwrak: Mali is only semi-open due to reverse engineering: http://limadriver.org/ | 01:23 |
| arossDOTme | oh and /proc/filesystems didn't exist | 01:26 |
| wpwrak | pabs3: what enabled lima to do successful reverse-engineering while that didn't happen with, say, powervr ? developer interest/skills ? corporate non-hostility ? luck ? | 01:30 |
| pabs3 | theres a reversing project for powervr too: http://powervr.gnu.org.ve/ | 01:31 |
| whitequark | wpwrak: my guess is that lima is a pretty straightforward arch | 01:32 |
| wpwrak | arossDOTme: odd. hmm .. all my bens that are in a runnable state run jlime, so in can't check if openwrt really doesn't have /proc/filesystems. is /proc mounted at all ? | 01:32 |
| whitequark | *mali | 01:32 |
| pabs3 | powervr re is making some progress too, not as much as lima though: http://listas.gnu.org.ve/pipermail/powervr-devel/2012-October/000054.html | 01:33 |
| whitequark | the company behind mali was even bought by arm, and they do tend to have affection for cores of very good quality | 01:33 |
| whitequark | and afaik powervr was designed by monkeys high on lsd | 01:33 |
| pabs3 | anyway, mali/etc is a bit offtopic here :) | 01:33 |
| whitequark | or something close to that | 01:33 |
| wpwrak | well, it's always good to know how gfx support is coming along, considering it's still such a pain | 01:35 |
| whitequark | folks on #lima are quite responsive | 01:35 |
| arossDOTme | /proc/filesystems exists with my 2GB ext2 card. | 01:44 |
| arossDOTme | but not with the reformated ext4 32GB one | 01:44 |
| arossDOTme | wpwrak:^ | 01:45 |
| wpwrak | arossDOTme: hmm. so your root file system is on SD, not in NAND ? i.e., you're running quite different systems, depending on the card | 01:50 |
| arossDOTme | no no. Just things like music on the sd card | 01:51 |
| arossDOTme | wpwrak: hmm. perhaps its my stupid brain. umount 2GB card and inserted 32gb. /proc/filesystems still exists. | 01:53 |
| wpwrak | good :) | 01:54 |
| wpwrak | and ext4 is listed in /proc/filesystems ? | 01:54 |
| wpwrak | (cat /proc/filesystems) | 01:55 |
| wpwrak | (it's just a list of the file system drivers available in your kernel) | 01:55 |
| arossDOTme | on the NN: e2fsck says: superblock invaid. trying backups. back magic number in super block while trying to open ...blar blar balr | 01:56 |
| arossDOTme | no ext4 in /proc/filesystems does have the sd card (mmcb1k0p1) | 01:58 |
| arossDOTme | remmber reading about /proc/filesystems but I forgets... | 01:58 |
| arossDOTme | and mount just fails: invalid argument | 01:59 |
| arossDOTme | oh and it mounts fine on my Trisquel pc install | 02:02 |
| wpwrak | maybe ext4 is simply not enabled on the system running on your ben. you're using openwrt ? | 02:03 |
| arossDOTme | yep | 02:03 |
| wpwrak | xiangfu tends to show up around this time. he'll know what is in there and what isn't. (and there's probably a package that would add whatever is missing ;-) | 02:05 |
| arossDOTme | But what I don't get is I thought I had used ext4 in the past no problems. maybe it's my fooled brain. Planing to try new NN img vir a bootable sd card. I guess I see what happens then?... | 02:05 |
| arossDOTme | hmm also need to got to bed | 02:06 |
| arossDOTme | opgk install kmod-fs-ext4? | 02:08 |
| wpwrak | that module sounds useful, yes | 02:15 |
| wpwrak | not sure what you need to do to get e2fsck with ext4 | 02:15 |
| arossDOTme | dependency fail | 02:15 |
| wpwrak | always fun :) | 02:16 |
| arossDOTme | ...:kennel | 02:16 |
| arossDOTme | just line on puppy (gnu?/linux) | 02:16 |
| arossDOTme | line = like | 02:16 |
| arossDOTme | e2fsck supports ext4 | 02:19 |
| arossDOTme | on ubuntu that is | 02:19 |
| wpwrak | yeah, but the one on your ben apparently doesn't | 02:20 |
| arossDOTme | :| | 02:20 |
| arossDOTme | would a file system in a file do for a test? | 02:21 |
| wpwrak | now we have to wait for someone to show up who knows how this can be remedied. could of course be that ext4 is just disabled in e2fsck on openwrt. | 02:21 |
| wpwrak | to test what ? | 02:21 |
| wpwrak | hah, speak of the devil ;-) | 02:22 |
| arossDOTme | so a file sonsiting of ext4 fs on working ext2 2gb sdcard and e2fsck the ext4 fs file. | 02:22 |
| wpwrak | xiangfu: arossDOTme is trying to use an ext4 file system on his ben. he ran into two problems: 1) no ext4 in the kernel (and kmod-fs-ext4 has some dependency issue). 2) e2fsck doesn't seem to support ext4. | 02:23 |
| arossDOTme | xiangfu: could you please look in the logs :) thanks | 02:23 |
| arossDOTme | that was quick | 02:23 |
| wpwrak | xiangfu: things he hasn't told us yet: 1) which version of openwrt exactly he is running; 2) what exactly the dependency issue was (i.e., a complaint from opkg, from insmod, ...) | 02:24 |
| arossDOTme | I have kenal | 02:25 |
| arossDOTme | version num looks the same though | 02:25 |
| arossDOTme | :/ | 02:25 |
| wpwrak | arossDOTme: (fs in file) naw, i think for now we can assume your sd card is healthy. | 02:25 |
| wpwrak | maybe put the dependency error message in a pastebin | 02:26 |
| arossDOTme | hag on | 02:26 |
| wpwrak | wife interrupt ? (-:C | 02:26 |
| arossDOTme | nope just getting to over load of things to do. 3 things in my mem and thats it. | 02:27 |
| arossDOTme | its also 2:27am | 02:28 |
| arossDOTme | no wife. only age 17, 18 in dec | 02:28 |
| xiangfu | arossDOTme, we have ext4 in latest kernel. | 02:30 |
| arossDOTme | Image_2012-04-09 | 02:30 |
| xiangfu | as wpwrak said. which version of openwrt (check by cat /etc/VERSION), | 02:30 |
| arossDOTme | ^ | 02:31 |
| xiangfu | arossDOTme, Image_2012-04-09, it also have ext4 support. (http://downloads.qi-hardware.com/software/images/NanoNote/Ben/2012-04-09/kernel.config). | 02:31 |
| xiangfu | arossDOTme, what is the 'dmesg' output when you plug-in the memcard. | 02:31 |
| arossDOTme | now I cant mount the flippng 2gb card. | 02:36 |
| arossDOTme | dmsg comming up | 02:36 |
| arossDOTme | rebooted now I can mount the 2gb card again. | 02:38 |
| arossDOTme | btw I see "libpng: read error " on shutdown. don't remmber getting this a few weeks ago. Could it be my os fs is corrupt? can't find doc on fsck / | 02:43 |
| wpwrak | the 2 gb card is also ext4 ? | 02:49 |
| wpwrak | (you can also check this in /proc/mounts. somewhat hard to read, but it has lots of useful information.) | 02:49 |
| arossDOTme | no ext2 | 02:50 |
| arossDOTme | that was it I remember reading about /proc/mounts not /proc/partitions | 02:52 |
| arossDOTme | 2gb ext2 dmsg: http://www.pastebay.net/1153457 | 02:53 |
| arossDOTme | 32gb ext4 dmsg: http://www.pastebay.net/1153458 | 02:54 |
| arossDOTme | xiangfu: ^ | 02:55 |
| arossDOTme | wpwrak: ^ | 02:55 |
| arossDOTme | thanks for bearing with me. | 02:55 |
| arossDOTme | oh dear 3:00 am | 02:56 |
| wpwrak | the most productive time of that day ;-) | 02:57 |
| wpwrak | s/that/the | 02:57 |
| arossDOTme | oh nice bot | 02:58 |
| arossDOTme | qi-bot: Who's a good bot? hay? :) | 02:58 |
| arossDOTme | *pats bot on head | 02:59 |
| arossDOTme | :) | 02:59 |
| xiangfu | arossDOTme, the dmesg shows it not mount 32gb card automatically. you can try run 'mkdir -p /mnt/mmcblk0p1; mount /dev/mmcblk0p1 /mnt/mmcblk0p1' | 03:02 |
| arossDOTme | already tried mounting manual | 03:03 |
| arossDOTme | I get fail: invalid argument | 03:04 |
| arossDOTme | xiangfu: | 03:04 |
| wpwrak | dmesg ? | 03:06 |
| arossDOTme | nothing | 03:07 |
| wpwrak | hmm | 03:11 |
| arossDOTme | could you post replys and I will have a look at the logs after sleep. please thanks btw when are you 2 online? | 03:13 |
| arossDOTme | xiangfu: ^ | 03:13 |
| wpwrak | in my case, highly variable :) | 03:16 |
| arossDOTme | arr | 03:17 |
| arossDOTme | any thing before i fall a sleep? | 03:18 |
| wpwrak | maybe the solution will come to you in your dreams :) | 03:18 |
| xiangfu | arossDOTme, no clue. I guess you can try ext4 on your 2GB cards. when you get up. :) | 03:19 |
| arossDOTme | so the file system in a file test then... | 03:19 |
| arossDOTme | don't have to reformat my sd card then he he he | 03:19 |
| arossDOTme | so how to file system check nand? | 03:20 |
| arossDOTme | then again might well reformat sd card anyway | 03:21 |
| arossDOTme | bye bye | 03:23 |

| arossDOTme | oh forgot to ask did the partition table matter? | 15:10 |
| arossDOTme | The 2gb sdcard formatted ext4 mounts! | 16:26 |
| arossDOTme | the working ext4 sd card have a msdos partition table. the 32gb card that does not work has a gpt partition table. | 16:42 |
| arossDOTme | wpwrak:^ | 16:43 |
| arossDOTme | xiangfu: ^ | 16:43 |
| kristianpaul | ah gpt, i had issues with that on my laptop... bios dint liked it i guess | 16:45 |
| arossDOTme | the sd card is fine on my pc | 16:46 |
| arossDOTme | you might what to see the wed 7 nov irc log for background info. | 16:47 |
| viric | there is a kernel setting for gpt partition tables iirc | 16:48 |
| arossDOTme | don't know. lacking knowage. be back in 30mins. doy needs a walk. | 16:49 |
| viric | hm now I think I'm wrong | 16:53 |
