2012-11-07 00:22 <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?

2012-11-07 01:23 <pabs3> wpwrak: Mali is only semi-open due to reverse engineering: http://limadriver.org/
2012-11-07 01:26 <arossDOTme> oh and  /proc/filesystems didn't exist
2012-11-07 01:30 <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 ?
2012-11-07 01:31 <pabs3> theres a reversing project for powervr too: http://powervr.gnu.org.ve/
2012-11-07 01:32 <whitequark> wpwrak: my guess is that lima is a pretty straightforward arch
2012-11-07 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 ?
2012-11-07 01:32 <whitequark> *mali
2012-11-07 01:33 <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
2012-11-07 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
2012-11-07 01:33 <whitequark> and afaik powervr was designed by monkeys high on lsd
2012-11-07 01:33 <pabs3> anyway, mali/etc is a bit offtopic here :)
2012-11-07 01:33 <whitequark> or something close to that
2012-11-07 01:35 <wpwrak> well, it's always good to know how gfx support is coming along, considering it's still such a pain
2012-11-07 01:35 <whitequark> folks on #lima are quite responsive
2012-11-07 01:44 <arossDOTme>  /proc/filesystems exists with my 2GB ext2 card.
2012-11-07 01:44 <arossDOTme> but not with the reformated ext4 32GB one
2012-11-07 01:45 <arossDOTme> wpwrak:^
2012-11-07 01:50 <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
2012-11-07 01:50 emeb has quit [Quit: Leaving.]
2012-11-07 01:51 <arossDOTme> no no. Just things like music on the sd card
2012-11-07 01:53 <arossDOTme> wpwrak: hmm. perhaps its my stupid brain. umount 2GB card and inserted 32gb.  /proc/filesystems still exists.
2012-11-07 01:54 <wpwrak> good :)
2012-11-07 01:54 <wpwrak> and ext4 is listed in /proc/filesystems ?
2012-11-07 01:55 <wpwrak> (cat /proc/filesystems)
2012-11-07 01:55 <wpwrak> (it's just a list of the file system drivers available in your kernel)
2012-11-07 01:56 <arossDOTme> on the NN: e2fsck says: superblock invaid. trying backups. back magic number in super block while trying to open ...blar blar balr
2012-11-07 01:58 <arossDOTme> no ext4 in /proc/filesystems does have the sd card (mmcb1k0p1)
2012-11-07 01:58 <arossDOTme> remmber reading about /proc/filesystems but I forgets...
2012-11-07 01:59 <arossDOTme> and mount just fails: invalid argument
2012-11-07 02:02 <arossDOTme> oh and it mounts fine on my Trisquel pc install
2012-11-07 02:03 <wpwrak> maybe ext4 is simply not enabled on the system running on your ben. you're using openwrt ?
2012-11-07 02:03 <arossDOTme> yep
2012-11-07 02:05 <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 ;-)
2012-11-07 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?...
2012-11-07 02:06 <arossDOTme> hmm also need to got to bed
2012-11-07 02:08 <arossDOTme> opgk install kmod-fs-ext4?
2012-11-07 02:15 <wpwrak> that module sounds useful, yes
2012-11-07 02:15 <wpwrak> not sure what you need to do to get e2fsck with ext4
2012-11-07 02:15 <arossDOTme> dependency fail
2012-11-07 02:16 <wpwrak> always fun :)
2012-11-07 02:16 <arossDOTme> ...:kennel
2012-11-07 02:16 <arossDOTme> just line on puppy (gnu?/linux)
2012-11-07 02:16 <arossDOTme> line = like
2012-11-07 02:19 <arossDOTme> e2fsck supports ext4
2012-11-07 02:19 <arossDOTme> on ubuntu that is
2012-11-07 02:20 <wpwrak> yeah, but the one on your ben apparently doesn't
2012-11-07 02:20 <arossDOTme> :|
2012-11-07 02:21 <arossDOTme> would a file system in a file do for a test?
2012-11-07 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.
2012-11-07 02:21 <wpwrak> to test what ?
2012-11-07 02:22 xiangfu has joined #qi-hardware
2012-11-07 02:22 <wpwrak> hah, speak of the devil ;-)
2012-11-07 02:22 <arossDOTme> so a file sonsiting of ext4 fs on working ext2 2gb sdcard and e2fsck the ext4 fs file.
2012-11-07 02:23 <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.
2012-11-07 02:23 <arossDOTme> xiangfu: could you please look in the logs :) thanks
2012-11-07 02:23 <arossDOTme> that was quick
2012-11-07 02:24 <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, ...)
2012-11-07 02:25 <arossDOTme> I have kenal
2012-11-07 02:25 <arossDOTme> version num looks the same though
2012-11-07 02:25 <arossDOTme> :/
2012-11-07 02:25 <wpwrak> arossDOTme: (fs in file) naw, i think for now we can assume your sd card is healthy.
2012-11-07 02:26 <wpwrak> maybe put the dependency error message in a pastebin
2012-11-07 02:26 <arossDOTme> hag on
2012-11-07 02:26 <wpwrak> wife interrupt ? (-:C

2012-11-07 02:30 <xiangfu> arossDOTme, we have ext4 in latest kernel.
2012-11-07 02:30 <arossDOTme> Image_2012-04-09
2012-11-07 02:30 <xiangfu> as wpwrak said. which version of openwrt (check by cat /etc/VERSION),
2012-11-07 02:31 <arossDOTme> ^
2012-11-07 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).
2012-11-07 02:31 <xiangfu> arossDOTme, what is the 'dmesg' output when you plug-in the memcard.
2012-11-07 02:36 <arossDOTme> now I cant mount the flippng 2gb card.
2012-11-07 02:36 <arossDOTme> dmsg comming up
2012-11-07 02:38 <arossDOTme> rebooted now I can mount the 2gb card again.

2012-11-07 02:49 <wpwrak> the 2 gb card is also ext4 ?
2012-11-07 02:49 <wpwrak> (you can also check this in /proc/mounts. somewhat hard to read, but it has lots of useful information.)
2012-11-07 02:50 <arossDOTme> no ext2
2012-11-07 02:52 <arossDOTme> that was it I remember reading about /proc/mounts not /proc/partitions

2012-11-07 03:02 <xiangfu> arossDOTme, the dmesg shows it not mount 32gb card automatically. you can try run 'mkdir -p /mnt/mmcblk0p1; mount /dev/mmcblk0p1 /mnt/mmcblk0p1'
2012-11-07 03:03 <arossDOTme> already tried mounting manual

2012-11-07 03:13 <arossDOTme> could you post replys and I will have a look at the logs after sleep. please thanks btw when are you 2 online?
2012-11-07 03:13 <arossDOTme> xiangfu: ^
2012-11-07 03:16 <wpwrak> in my case, highly variable :)
2012-11-07 03:17 <arossDOTme> arr
2012-11-07 03:18 <arossDOTme> any thing before i fall a sleep?
2012-11-07 03:18 <wpwrak> maybe the solution will come to you in your dreams :)
2012-11-07 03:19 <xiangfu> arossDOTme, no clue. I guess you can try ext4 on your 2GB cards. when you get up. :)
2012-11-07 03:19 <arossDOTme> so the file system in a file test then...
2012-11-07 03:19 <arossDOTme> don't have to reformat my sd card then he he he
2012-11-07 03:20 <arossDOTme> so how to file system check nand?
2012-11-07 03:21 <arossDOTme> then again might well reformat sd card anyway
