[SOLVED] How to cancel systemd-fsck during reboot after power failure.

Hello

If power fails (or if I, for any reason, force a physical shutdown ) on my computer, it will display during boot :

systemd-fsck[171] : arch_data was not cleanly unmounted, check forced

And then hangs for a long time (10 minutes ) while checking arch_home partition, wich is a 1T ext4 partition.
then finish the boot.

Sometimes i want this behavior, but i may need to have my computer up and running as fast as possible, and i don't seem to be able to cancel this fsck.

Ctrl+C, or escape have no effect.

How to allow cancelation of system-fsck for this boot, postponing it for the next boot ?

my fstab :

# 
# /etc/fstab: static file system information
#
# <file system> <dir>   <type>  <options>   <dump>  <pass>
# UUID=cfdf8739-d512-4d99-9893-437a6a3c9bf4 LABEL=Arch root

IIRC you can't cancel a fsck in systemd.
Doesn't the fsck tool also fix things?

Usually it does, some "orphaned nodes" . However i don't think they are critical and forbid the system to boot.

Have you tried adding 'fsck.mode=skip' to the kernel command line?

"fsck.mode=skip" work indeed
I just edit the grub line during the boot, and no fsck are performed, next boot it will be done.
I had think only of cancel the fsck, not skip, so it's a nice work around for my problem and i consider it solved.

If you'd rather the filesystem not be fsck'd, why do you explicitly ask for it in /etc/fstab?

maybe you did not read my first message.
I do want it to be fsck'd when it is necessary, but sometimes i want to boot directly, even if systemd want to fsck.

Re: [SOLVED] How to cancel systemd-fsck during reboot after power failure.

I am a noob.  But what you are saying is like, I got in an accident, but only my front bumper is dented, and I can still run the truck.

I would think if you don't look at the dent, that it might cause more problems for you.
But then, maybe not.

However, good luck.

Re: [SOLVED] How to cancel systemd-fsck during reboot after power failure.

Maybe you can add a menu item to the grub boot menu so you can pick it from the menu instead of editing the grub line by hand?
I'm using syslinux, but I can have menu items that only differ in e.g. 'quiet' parameter:

APPEND root=/dev/sda3 rw init=/usr/lib/systemd/systemd quiet

APPEND root=/dev/sda3 rw init=/usr/lib/systemd/systemd

Everything else is the same.

@Kilzool  : Let's say i'm in a skype meeting with my boss, and i got a power failure. should i ask him to wait 10 minutes before i come online again ?

@karol : You're right, this is the right way to do it ! thank you very much !
