[SOLVED] Btrfs Scanning How do I stop it?

Sector11 · 2017-06-15 05:22:26

When I boot GRUB is scanning for any btrfs partitions/systems.

I don't have any that I know of.

So how can I tell GRUB so stop scanning it's not needed?

How do you know it's GRUB?

What *exactly* happens when you boot, please include as much detail as possible.

Well, whatever checks the file systems when one boots their machine.

It displays a message saying it is checking for btrfs, then continues checking the mounted partitions. ahhh ... then goes to GRUB for the menu ... so something before grub maybe.

Interesting, no idea why it's here.

Probably part of the default install. Applications like gparted need the btrfs-tools (xfs-tools etc ...) to create a btrfs file system when you patition the disk so it needs to be in the live system; or to create a btrfs file system post-install.

^ except:

Package: btrfs-tools
State: installed
Automatically installed: no

so it looks like I installed it but I don't recall doing so and I use: "--no-recommends"

No problem it's gone

Correct.

Packages installed with the system will not be marked "automatically installed" unless they were brought in by a dependency.

Now that I did not know. Time to look for it in the list.
It must be something added with the BL-D ISO than. Any idea what brought it in?

EDIT: Never mind #14 on the list.

I don't think it's any big deal really. It does a quick check and adds a line to the boot messages, but how many milliseconds does it add to the boot time? Did you notice any difference after removing it?

Sector11 · 2017-06-17 03:47:47

This was one of a few problems I am was having ... I'm eliminating things not needed, not wanted.

Even so, it was certainly not long, but why have it in the first place if I don't need it, same goes for all things; wireless and intel - no need: remove them. It only appeared with this install.

BIOS now set to fast boot, I basically see nothing: Push the Power button, 2-3, Username - Password, enter.

You can disable the unit file whilst keeping the package installed.

Use this command to show all of the unit files being launched by systemd:

systemd-analyze blame

Then find all the .services (or .sockets) that you don't want and use:

sudo systemctl disable foo.service # replace "foo" with the name of the .service

One of the irritating things about Debian is it's propensity to automatically enable .services upon installation, some may like this but I don't.

Intertesting, I'll open a new thread later because I have some questions.
