Disable Scanning For Btrfs File Systems In Ubuntu

On Ubuntu 18.04 you can uninstall btrfs-support with
apt purge btrfs-progs
But that probably wouldn't save you much boot time. On my system the reason was, that I don't have a swap partition but on boot it is searched for such for about 30 seconds (while displaying the btrfs-scan).
remove the swap check
- open
/etc/initramfs-tools/conf.d/resume
- replace
RESUME=UUID=xxx
withRESUME=none
- issue
sudo update-initramfs -u
- reboot your system
(create the file if it does not exist and just add RESUME=none
in it)
The btrfs-tools
package adds an action to the initramfs to load the btrfs module. If you purge that package (sudo apt-get purge btrfs-tools
), followed by an update-initramfs -ukall
if the uninstallation doesn't do it already, that should go away (though I've not tested it). If it doesn't, you can always blacklist the brtfs
module in /etc/modprobe.d
.
Btrfs isn’t too much stable to be used as deafult file-system. Most Linux distributions, probable all, are still using ext4 as primary file-system. So, you can completely remove it from your computer. Try the given command:
sudo apt-get purge btrfs-tools
This command will remove btrfs-tools from your computer. You may need to wait some minutes to complete the process. Your initramfs should be updated automatically but if not happen, do it by this command:
sudo update-initramfs -ukall
Then make a grub update:
sudo update-grub
All is well. Now make a restart. Hope your Ubuntu will start successfully this time.
