Archlinux Startup - How can I speed it up?

abraham10 · 2010-05-30 18:58:50

How can I make it so that when I start up arch it doesn't check the file systems automatically.

This is what I mean:

Also, could someone explain to me what is happening here:

and is there anyway I could speed up the timeout in blue area.

I don't know if what I want to do is good practice but I just want to speed up my boot time... thanks in advance!

Google finds these:

Maybe they will help.

File system checking is always done at boot time, I don't know what you want to achieve by removing that. It's pretty vital after all... Unless you implement some substitute for it I'd keep my hands off it if I were you. Judging by your second question (which gives us a hint about what you do and don't know), I don't think you fully understand how essential it is. No offense .

fsck doesn't take a lot of time. If you use windows, chkdsk takes like an hour and forces you to reboot. Not fsck. Also, for your second question, that is when it mounts the filesystem and starts the init process, which basically is the part when it allows your data to be read. init starts the programs in you /etc/inittab, and basically spawns the processes for a usable system.

@ .:B:. That is why I'm asking and I would like my questions to be answered not criticized. Also if you would look at the area I'm in maybe that would tell you that I'm a newb... and damn proud of it !

1) it doesn't actually check. is just list some information nothing more. if it was checking, you should have a progress bar.
2) what to speed up if is nothing to speed up? in that blue area is just saying it could wait 10 second but actually doesn't since the device is already there.

in conclusion, nothing that was marked in there is an issue.

abraham10 · 2010-05-30 19:27:59

Yeah thanks for everyone that helped I know that what I'm posting is not really an issue but more of accommodation. I'm just looking for ways to speed up the start up process. I've seen on youtube where people have been successful in booting up fully under 5 seconds and I would like to achieve something close to that.

I am not criticising your endeavour; I am trying to understand why you want to do it (and I guess you just explained by mentioning the < 5s boot time). Explaining why you wanted it in the first place wouldn't have prompted me to ask that question - so excuse me for being curious.

You can disable the check in the init scripts I believe; you should also unset the flag on the file systems themselves that tell the mount utilities to fsck the partitions after X mounts.

Yeah... ok .

fsckd · 2010-05-30 19:49:10

You can get Arch to boot in 5 seconds with the possible loss of stability, etc. Search the forums, there was a big thread on this last year.

And if you don't want any more confusion, change the subject to something like "Arch Startup Issues - How do I gotz speed?"

Edit: And change the first post accordingly.

Edit2: Better yet, start a new thread.

Edit3: MOAR Edits required.

My personal favorite way to lose stability is to pacman -Syu the sucker.

EDIT: Oh, I forgot to mention the part where I throw my laptop at the wall...that was a crucial part to losing stability

wonder · 2010-05-30 20:27:35

you can mess around with quick-init http://aur.archlinux.org/packages.php?ID=25563

karol · 2010-05-30 21:16:17

If you choose ext3 as your fs, then fsck takes a bit time. It's *much* faster w/ ext4.

And plz change teh title.

It works well

I can haz 6 sekond boot

abraham10 · 2010-05-30 21:32:56

Yeah well I'll give a try @ quick-init thanks for the suggestion, but right now I have a 36 second startup and if I can cut down half the time I would be happy.

36??? that's a lot but i guess that virtualbox is the fault here. i found it very slow this days. seems that along with success comes degradations.

abraham10 · 2010-05-30 21:42:09

VB is just for my test OS. Once I have it fully configured the way I want I will implement it for real.

Is there a tutorial on the installation of quick-init I found the original page http://www.obliquo.net/?articles/quick-init.html and this http://bbs.archlinux.org/viewtopic.php?id=72156 if there is one there I can't find it. I also downloaded the tarball from here: http://aur.archlinux.org/packages.php?ID=25563

Read the wiki on how to use AUR .

Also, I don't know if you tried it yet but backgrounding daemons can speed things a lot, it's usually the first thing to try. If you're not sure what this is about post the daemons part of your /etc/rc.conf file and we'll try to help

andresp · 2010-05-30 22:13:20

Just hack at rc.sysinit and friends

#if /bin/grep -q " verbose" /proc/cmdline; then
read opts /proc/cmdline; case $opts in *verbose*)

#if [ -f /etc/crypttab -a -n "$(/bin/grep -v ^# /etc/crypttab | /bin/grep -v ^$)" ]; then
if [ -f /etc/crypttab ] && /bin/grep -vq '^$#\|$$' /etc/crypttab

# (
{
/sbin/modprobe -q dm-mod 2>/dev/null
/sbin/hwclock --adjust
/sbin/hwclock $HWCLOCK_PARAMS
# ) &
} &

etc... there are tons of lines like this

abraham10 · 2010-05-31 01:23:16

Here are my daemons from my rc.conf file:

Hm, I was wondering as well how to move the fsck check (granted, it only happens once a month...) from booting sequence to shutdown sequence - at least on my desktop. To disable it completely I'd change my fstab accordingly I suppose, but where does it get called on the bootup process? Hm, /scratches head and makes a mental note to read boot sequence wiki/...

Barrucadu · 2010-05-31 08:35:04

Grep /etc/rc.sysinit for fsck, then I suppose you could just move that whole block of code to /etc/rc.shutdown.
