Any idea how I can get a link to a motherboard manual from superuser.com/questions/649674/… ?

allquixotic

you can always set it up in your web browser

no need to run it on a server

Hennes

If I go to the pages, click on support and manuals it gives me a list to downloas from.

Every one of them works, yet the link point to javascript:void()

So I tried Firebug and webscarab but the best I can do is some submitted XML to the webserver at asus.com, but I fail to find a direct download link

allquixotic

@Hennes there may not be a direct download link

you have to submit a POST request

Hennes

Could be. Or I just missed how to get at it (which was half the fun)

allquixotic

you could of course write some JS that does the same thing and host it on raw github

Hennes

18:22

Might be a tad overkill for a question which already got an answer while I searched for my link to include in an answer.

Also, the manual does not have the information on how to use the motherboard with multiple monitors.

allquixotic

if it's not useful then don't make me get interested in it, darn it D:

@Hennes Hover mouse cursor on link and your browser will extend it.

allquixotic

18:27

or even http://dlcdnet.asus.com/pub/ASUS/mb/socketAM3/M4A78LT-M/E5232_M4A78LT-M_manual.‌zip

Hennes

Aye, and then you move the mouse to the bottom of the screen and it disappears again. So manual copying it now

Bob

@all well, I need to set up enough to run the node build

allquixotic

right-click copy link location...?

Bob

I suppose I could just concat all the files? dunno

allquixotic

@Bob the minify step will fail, but just having node.exe is enough to run the build to master.js

Hennes

18:28

Ah, that works.

I always took the 'solution' of writing [URL](URL) when in chat

allquixotic

also if you run the nodejs installer you can run npm install uglify-js2 on cmd.exe to get that part installed also

Bob

why will the min fail?

oh

allquixotic

@Bob it depends on uglify-js2 which isn't installed out of the box

if you download the standalone node.exe, npm won't work, but if you do the full installer, it'll put it on your PATH

so the build prep instructions on windows are literally 2 things: run the nodejs installer package, then cmd.exe, then npm install uglify-js2

then node build.js

then open master.min.js in FF and it'll run you a bot

Bob

hmm...I have distinct memories of running a bot from my Linux netbook

forgot how I built that one

allquixotic

i wonder if you could ask the bot to eval the contents of... a nested bot :D

that would be funny

Hello all. Almost done with my migration of the root file system and boot process from HDD to SSD, but hit a little bit of a snag. Does anyone in here feel up to helping me troubleshoot a little (Linux and possibly GRUB 2)?

allquixotic

@MichaelKjörling under other circumstances, yes, but I'm working from home atm on a Saturday

@allquixotic Aw drat :( U&L chat seems pretty dead... last post 13 hours ago.

@OliverSalzburg are you kidding? I check root access more often when I'm actually sitting at my desk at work

the only reason I'm not procrastinating for hours on end is that I have a very short time limit for this

Oliver Salzburg

Michael Kjörling

How about you @OliverSalzburg?

allquixotic

totally got my hands dirty atm

Michael Kjörling

Well, I'll recite the problem and if anyone feels up to helping me figure out what to do about it, I'd really appreciate it.

allquixotic

@MichaelKjörling lol, they are always there, you might catch terdon or slm ;).

Michael Kjörling

20:17

I'll give it a try there too and see where I get help the fastest ;)

allquixotic

aside from that, chat is asynchronous, so even if you ask a question now, someone could provide a good response many minutes or hours later if they see it

and often faster than what you'd get on the main site by asking a Q (although your question may be OT due to specificity and "troubleshooting" nature -- that might be OK on U&L, but not on SU)

Michael Kjörling

Yes, the troubleshooting part is why I thought chat would be more appropriate. I don't mind posting a Q&A with the findings though.

Braiam

mm... to access a ipv6 using the browser I just type the address (I want to hit a specific ip)?

ohhh

yeah, firefox can't find the ip...

Michael Kjörling

20:20

With IPv6 you have to put literal IP addresses within square brackets; the colons mess it up otherwise.

Don't have IPv6 connectivity unfortunately so can't really offer any assistance. And I'm not even sure if my local Apache is configured to listen on v6.

Anyway. Situation: boot process migrated from HDD to SSD, HDD now physically removed from system. Root file system migrated from plain ext3 to ext4 on RAID 1 MD (currently with only a single device out of two, but that's unrelated). GRUB command list points the Linux kernel at "root=/dev/md0 ro" with a search --set=root preceding naming the UUID of the root ext4 file system.

Updated fstab to name /dev/md0 for the root fs. On boot, the root file system check fails with "/dev/md0 mounted" and asks for root password for maintenance; if I hit Ctrl+D to abort that, then the boot completes successfully. Why is e2fsck complaining that md0 is mounted? (Well, it is mounted, but no more than any other root fs on boot...)

Braiam

hack, the aiccu client was dead...

Hennes

It seems similar to old slackware (2.4) complaining about / being mounted. (No RAID stuff, old ext2, sw 2, kernel 1.2.13.) But that was complaining about it being mounted RW and you have the RO option. Are you sure that that RO option is recognised?

Braiam

@MichaelKjörling nah, found the problem, stupid tunnel was down

Michael Kjörling

@Hennes I haven't confirmed, but can't see any reason why it suddenly shouldn't be recognized? I used rsync -avxHAXS to transfer the root file system, then cp -av in Busybox (Debian Wheezy install CD in rescue mode) to transfer the contents of the old /boot partition into /boot on the new root file system.

No errors were reported during the copying.

Braiam

@MichaelKjörling did you reinstalled grub? sometimes grub is sloopy

Michael Kjörling

20:25

Yes, I did. It wouldn't work otherwise, with the disk it used to be on gone :)

Hennes

If I knew a hard/good reason I would have stated it.
However it just reminds me of the same problem.

Michael Kjörling

Let me check dmesg.

Braiam

wait, the thing boots?

Michael Kjörling

Yes, absolutely.

allquixotic

if you're sure it's e2fsck and you want it to STFU, you could put an interposer in there in place of it, either /bin/true or re-write its command line args, or something like that

Michael Kjörling

20:26

I'm using it now (though am not getting the full performance benefit from the SSD yet as /usr is on spinning rust)

allquixotic

could be instructive to at least log to a file whatever its args are

Michael Kjörling

I'd rather it checks my root file system when needed :)

Anyway, here's what dmesg has to say about the kernel command line: Command line: BOOT_IMAGE=/boot/vmlinuz-3.2.0-4-amd64 root=/dev/md0 ro quiet pci=nomsi

allquixotic

yeah but you aren't going to be able to fix it until e2fsck is happy, and to know why it's sad, you need to get its args

then you can manually execute e2fsck with the same args and interpret the args and figure out if it's wrong

maybe e2fsck thinks it's still an ext3 volume but it has extents which throws it for a loop

Michael Kjörling

e2fsck -n /dev/md0 while running says the file system is clean.

It does print out a couple of warnings relating to the -n and running part, but nothing bad aside from that.

allquixotic

I forgot that e2fsck is ridiculously strict about online checking

.
Note that in general it is not safe to run e2fsck on mounted filesystems. The only exception is if the -n option is specified, and -c, -l, or -L options are not specified. However, even if it is safe to do so, the results printed by e2fsck are not valid if the filesystem is mounted. If e2fsck asks whether or not you should check a filesystem which is mounted, the only correct answer is ''no''. Only experts who really know what they are doing should consider answering this question in any other way.

Michael Kjörling

20:30

I prefer zpool scrub, but root on ZFS is a little... tricky on Linux, not to mention potentially fragile.

Yes, I know it isn't safe to e2fsck a mounted file system, that's why I told e2fsck -n "Make no changes to the filesystem". :)

allquixotic

it seems like what might be happening is that your fs is mounted before e2fsck is run, which is probably the wrong order, because a proper e2fsck (proper == both reliable at detecting errors and fixing them) will happen before it's mounted

so, something in your init scripts maybe

I doubt it's grub

Michael Kjörling

It seems to me that at the point e2fsck is run on the root file system, the fs should still be mounted according to the kernel command line which means it should be mounted read-only. Once the check completes it gets remounted read-write.

Yeah, I'm pretty sure it isn't GRUB either; it could have had something to do with passing kernel command line parameters, but I doubt it.

allquixotic

I don't think that it's supposed to be mounted at all when you do a potentially modifying e2fsck

not even RO

Michael Kjörling

I'm not sure when exactly Debian's boot scripts do the pivot-root, but I sort of doubt it's that late...

Looking at the actual boot script now that does the file system check.

It looks pretty much like the check is done while the root file system is explicitly mounted read-only. One comment even says as much: Ensure that root is quiescent and read-only before fsck'ing.

OK, this is rather funny. Here's an actual log from the most recent boot (uptime reports the system has been running since 21:07)...

Log of fsck -C -a -t ext4 /dev/md0
Sat Dec 7 21:06:34 2013

fsck from util-linux 2.20.1
/dev/md0: clean, 402340/2621440 files, 2780854/10485488 blocks

Sat Dec 7 21:06:34 2013

And then there is...

Log of fsck -C -R -A -a
Sat Dec 7 21:06:34 2013

fsck from util-linux 2.20.1
/dev/md0 is mounted.
e2fsck: Cannot continue, aborting.

fsck died with exit status 8

Sat Dec 7 21:06:34 2013

It definitely looks like the latter one applies.

Going to give putting the root fs by UUID in fstab a try, and see what happens. Back soon.

Boris_yo

20:51

@allquixotic No ADHD? Multitasking is okay?

Michael Kjörling

Putting the root fs UUID instead of /dev/md0 as the device in fstab didn't change anything, but I did get to have a look at the actual mount state at the time of the reported failure. /dev/md0 on / type ext4 (rw,relatime,errors=remount-ro,user_xattr,barrier=1,data=ordered). rw Where the h- does that come from? It would definitely seem to explain my problem.

Hennes

Yup.

Michael Kjörling

21:07

This is actually proper question material by now IMO. There's a clear problem here: the file system is mounted rw at a point when it is expected to be mounted ro. What's causing that? That's answerable.

Hennes

Sanity check for /etc/fstab. IS there one entry for / ?

Or two (one by device ID, one by UUID thingy ?

Michael Kjörling

Let me double-check, but there should only be one that isn't commented out.

Ohhhhhhhhh, I think you're on to something @Hennes. There's my old /mnt/new-root mount. Argh! Just let me try pulling that one out and see what happens on reboot.

Hennes

Something good came from my old Linux experience (moved to BSDs a decade ago).

Michael Kjörling

21:22

@Hennes Definitely. Sometimes it's an extra pair of eyes to see a problem from a fresh angle that's needed. That's why rubber duck troubleshooting helps, though it didn't in my case because my rubber duck hasn't been properly trained yet. :)

Clearly Debian's boot script got confused seeing two file systems for the same device where one was the root file system. I can't really blame it.
